1. How is decaf coffee made?

  • Coffee beans have been genetically engineered to grow caffeine-free.
  • Planters used artificial selection to eliminate caffeine producers in coffee plants.
  • Coffee beans are treated chemically to strip away the caffeine.
  • Decaf plants already existed in nature and did not require any intervention.

Coffee beans are treated chemically, usually by soaking them in ethyl acetate or methylene chloride (also an ingredient in paint remover). This harsh chemical bath strips out both the beans' caffeine and much of their flavor. U.K. company Tropic Biosciences is currently developing a coffee bean engineered to grow caffeine-free. CRISPR coffee promises a jitter-free cup of Joe, with all the roasty goodness of full-caf.

3. True or false: When you hold up the conch shell to your ear, the sound you hear is actually the ambient noise around you.

True. Conch shells are great at amplifying noise. Unfortunately, the conch's status as a tasty delicacy (not to mention its collectible shell) makes it at risk for overfishing, a fact compounded by the fine distinction between the thin-lipped juvenile (which should not be fished) and the thicker-lipped adult.

4. True or false: We will eventually need booster shots for COVID because immune responses to the vaccine decrease over time.

True. Ongoing research will tell us what that magic window is. Recently, a team of Israeli scientists published a seven months-long study of COVID-19 immunity in individuals who had received the Pfizer vaccine. They found that over that time, the patients' resistance to infection dropped from 95 percent to 39 percent. However, they also determined that vaccinated people remained more than 90 percent protected from severe disease.

False. The average size of new homes has been steadily shrinking since 2015, when a new single-family home averaged 2,740 square feet (255 square meters). The NAHB believes that the smaller overall sizes reflect a trend of builders adding more entry-level homes to the market.

2. A giant sacrificial object is burned every year during Santa Fe's Zozobra. What does this object resemble?

  • A scarecrow
  • A ghostly "boogeyman"
  • A heart
  • The Grim Reaper

3. True or false: Birds eat stones to help them digest food. These stones travel with the food through the digestive tract to help break food down during its journey.

False. Swallowed stones end up in the gizzard, which is a specialized, very muscular stomach attached to the "true stomach." These tiny stones help in the grinding of plant material — notoriously hard work, as the cellulose that makes up plant cells is tough and difficult to break down with stomach acids alone. After the gizzard has done its job, the food is passed back into the other stomach to be digested further. In the gizzard, gastroliths often eventually become rounded and smooth, and birds will sometimes regurgitate these, replacing them with sharper stones.

4. In the Victorian era, if a young lady saw a gentleman she knew out in public and recognized him, how must he then respond?

  • By touching the brim of his hat
  • By lifting his hat
  • By bowing in her direction
  • By giving a nod

If the young woman did see a gentleman friend and felt she couldn't ignore him, she would have to take the initiative and offer her hand. The gentleman had to wait for the lady to recognize him before lifting his hat (not simply touching the brim), and he had to use the hand farthest from her. If she offered her hand, the gentleman had to turn to walk with the lady instead of stopping. And above all else, the conversation itself had to be reserved: Cassell's dictates, "Strict reticence of speech and conduct should be observed in public," without "loud talking" or "animated discussions."

5. True or false: In the Victorian era, a widow was expected to don full mourning dress (deep black) for two years.

True. Mourning attire was a big deal in Victorian times. A widow was expected to wear deep black for two years; in the last six months, she could go into "half-mourning," which meant adding some white, gray or lavender colors alongside the black. Some widows, like Queen Victoria, wore mourning clothes for the rest of their lives.

3. Which of the following calendars is based off of the solar year, i.e., the time it takes for the Earth to revolve around the sun, rather than by the phases of the moon?

  • Traditional Chinese calendar
  • Western (Gregorian) Calendar
  • Islamic (Hijrī) Calendar
  • Jewish (Hebrew) Calendar

Much of the world today follows the Gregorian solar calendar, which has its origins in medieval Western Christianity. Conversely, the Islamic calendar or Hijrī, is a lunar calendar. There are 12 months in the Hijrī calendar, with each month being 29 or 30 days long. It would be over 32 to 33 years that the lunar calendar will completely cycle the solar calendar. That's why the Islamic fasting month of Ramadan can fall in October one year, and a few years later it would be in July. It also means that the Islamic New Year is never on the same date and would also depend on the sighting of the moon.

4. True or false: A systematic review of 237 studies on blood flow restriction training found that 78 percent reported a "significant" increase in muscle strength compared to a control group.

True. Once blood is allowed back into the muscles, your body will work extra hard to repair them, stimulating growth and strengthening. Essentially, this mimics the effects of very intense exercise using a much lower workload.

5. Who is most likely to be injured by turbulence on a commercial flight?

  • Pilots and co-pilots
  • Middle seat passengers
  • Aisle seat passengers
  • Flight attendants

Inflight turbulence is more than a mere nuisance. The FAA reports that 58 people are injured by turbulence on airplanes every year while not wearing their seat belts. And most aren't ticket-holding passengers, either. Of the 298 serious injuries from turbulence that the FAA recorded from 1980 to 2008, 184 involved flight attendants. Most of the turbulence happens at 30,000 feet or higher.

  • A species that has remained virtually unchanged superficially for millions of years.
  • A species that was thought to be extinct, only to be discovered at a later date.
  • A species that mimics the resemblance of other organisms or objects.

A species that appears to closely resemble their ancestors are often referred to as "living fossils" and species that take on the appearance of other organisms or objects are described as "mimetic."Lazarus species, on the other hand, refer to organisms thought to be extinct, or absent from the fossil record after showing up for several geologic periods. Lazarus is a reference from the Bible, who was raised from the dead by Jesus.

4. Myth or fact: Extremely spicy food can damage your taste buds.

Myth. Spicy foods do not physically damage your taste buds. When you're chowing down a spicy pepper, the chemical responsible for the hotness — capsaicin — sends a signal to your brain in the same way it would if there was an actual fire on your tongue. That's why the brain, which takes these things quite literally, sets off the body's sprinkler system. Your heart starts racing, firing up that "fight-or-flight" mechanism.

1. Myth or fact: Charging your cell phone overnight damages the battery, which reduces their total capacity.

In a survey of 350 people across the U.S., more than half of poll respondents believed that leaving their cell phones plugged in all night damaged or even ruined the device's battery. Fortunately, it's not true. Your smartphone is an advanced electronic device, one that's intelligent enough to prevent overcharging. However, your smartphone battery has a limited life no matter how you charge it. Current batteries might last for around 400 to 500 charging cycles; after that, you'll likely start noticing a reduction in your battery life throughout the day.

1. True or false: The 2.2 ton hardened mass that was found at Chernobyl's nuclear power plant, nicknamed the "Elephant's Foot," is an entirely harmless byproduct of the 1986 nuclear disaster.

False. The Elephant's Foot is extremely dangerous. At the time of the disaster, sensors told the emergency crews that the lava formation was so highly radioactive that it would take five minutes for a person to get a lethal amount of exposure. Furthermore scientists don't know how corium — a rare substance that composes the mass — might behave over the long term, like when it's stored in a nuclear waste repository. What we do know is that the mass is cooling down, but still remains highly radioactive.

5. How did Saipan, a lesser-known travel gem of the Mariana Islands, come into the possession of the United States?

  • The United States bought it from Germany.
  • They "won" the island during WWII.
  • The island was illegally annexed and taken by force.
  • They formed treaties with the local inhabitants and established an administration and police force to keep order.

Rule over the Mariana Islands jumped from country to country starting in the mid-1600s. It eventually fell under German control from 1899 to 1914, but then was taken by Japan during WWI, which saw it as a barrier to foreign invaders from the East. During WWII, the U.S. and Allied forces invaded, and the Japanese lost the nearly monthlong Battle of Saipan. The U.S. occupied the island and installed a military air base there, which became a turning point in WWII. Having a base so close to Japan meant the Allies could fly the U.S. Army's long-range B-29 Superfortress bombers to strike Japan directly.

6. True or false: Wasps, like bees, are powerful pollinators.

True. Wasps deserve more credit. What little we know about wasps is that they are excellent pollinators and, being apex predators, they are one of nature's most effective regulators of pest populations. Early research shows that wasps aren't picky about their prey, but will hunt down whatever insect is in abundance.

2. True or false: Due to its fast growing time, bamboo reaches maturity and can be harvested after three years.

True. Bamboo can grow as much as 3 feet (0.9 meters) per day and reaches harvest maturity in three years, while it can take trees 50 years or more. Bamboo harvested for bamboo toilet paper generates roughly 30 percent less greenhouse gas emissions compared to tree-based toilet paper. It requires no tending, irrigation or fertilization, and only needs to be harvested once a year.

3. True or false: Smoke from wildfires can become more toxic as it travels through the air and is exposed to the sun and chemicals.

True. How far the smoke travels from its origin affects the ability of smoke to "age," meaning to be acted upon by the sun and other chemicals in the air as it travels. Aging can make it more toxic. Importantly, large particles like what most people think of as ash do not typically travel that far from the fire, but small particles, or aerosols, can travel across continents.

4. True or false: Most cloth face masks protect against smoke particles.

False. Not all face masks protect against smoke particles. Most cloth masks will not capture small wood smoke particles.That requires an N95 mask in conjunction with fit testing for the mask and training in how to wear it. Without a proper fit, N95s do not work as well.

5. True or false: U.S. federal law forbids stealing someone else's WiFi.

False. There isn't a federal law against stealing someone's WiFi. The 1986 Computer Fraud and Abuse Act penalizes anyone who "intentionally accesses a computer without authorization or exceeds authorized access" but it was passed before WiFi was common. Some states have laws against stealing WiFi. In 2007, a court in Michigan let a man off on felony charges for stealing a WiFi signal from a coffee shop while parked in his car. The man had been checking his email and browsing the internet and said exactly that to a curious police officer. It was eventually determined the man had no idea what he was doing was illegal, let alone a felony. Nevertheless, he was fined $400 and 40 hours of community service.

Planets Quiz, July 17, 2021

1. What planet is so large that it creates an empty "barycenter" between itself and the sun, which they both orbit?

  • Uranus
  • Saturn
  • Neptune
  • Jupiter

The sun doesn't just exert gravity on Jupiter — Jupiter's so big that its own pull affects how the sun moves, too. The Sol-Jupiter barycenter sits 1.07 times the radius of the sun from the sun's center, or 7 percent the radius of the sun from the surface. The sun also orbits this spot; if you were to look at the planetary plane from above, you'd notice a slight wobble as the sun moves around the Milky Way.

2. True or false: Planets and stars are mostly spherical because their mass is so large that their body collapses onto itself.

True. Little items — like, say, a banana or a lug wrench — can resist this fate because their "self-gravity" is relatively weak, allowing them to retain non-spheroid shapes. However, in planets, suns and other truly massive bodies, the force is so strong that they can't avoid being distorted into spheroids.

3. What is gas giant Jupiter mostly composed of?

  • Hydrogen and helium
  • Oxygen and carbon dioxide
  • Methane and chlorine

5. True or false: Several moons in our solar system have active volcanoes.

True. The moons that have active volcanoes are Io, a moon of Jupiter; Triton, a moon of Neptune; and Enceladus, a moon of Saturn.

Related: Where did the moon come from?

6. True or false: Earth is the only planet in our solar system that has been confirmed to have tectonic plates.

True. Some scientists think the existence of plate tectonics could be a prerequisite for life. The plates tend to promote volcanic eruptions, which release carbon dioxide into the atmosphere. Such emissions help keep Earth's temperature nice and stable. And that's just one of the benefits they provide to organisms.

1. Roughly how many calories are burned by Tour de France cyclists who complete the race?

  • 20,000 calories, roughly 35 Big Macs
  • 60,000 calories, roughly 105 Big Macs
  • 120,000 calories, roughly 210 Big Macs
  • 240,000 calories, roughly 420 big macs

Top Tour de France cyclists who complete all 21 stages burn about 120,000 calories during the race — or an average of nearly 6,000 calories per stage. On some of the more difficult mountain stages — like this year's Stage 17 — racers will burn close to 8,000 calories. To make up for these huge energy losses, riders eat delectable treats such as jam rolls, energy bars and mouthwatering "jels" so they don't waste energy chewing.

4. Which is true about July 4?

  • Three U.S. presidents have died on July 4 and one was born.
  • One U.S. president has died on July 4 and three were born.
  • Two U.S. presidents have died on July 4 and two were born.

Incredibly, both Thomas Jefferson and his fellow Founding Father John Adams died on the very same day: July 4, 1826. Even more insane, that year was the 50th anniversary of the adoption of the Declaration of Independence. In 1831, just five years later, James Monroe became the third U.S. president to die on the Fourth of July. Calvin Coolidge is the only U.S. president who was born on the Fourth of July.

5. True or false: One of the best ways to treat a burn is to immediately put ice on it.

False. Using ice or ice water can do more harm than good. Extreme cold can cause further damage to the tissue. Cleveland Clinic advises running the wound under cool water for five minutes instead.

6. How long did Nasseri, an Iranian refugee, live in a France airport after he lost his refugee papers and couldn't continue to his final destination of Belgium.

  • 6 months
  • 18 months
  • 6 years
  • 18 years

His story reportedly inspired the movie "The Terminal," starring Tom Hanks. Without his papers, he could not board his plane for England. Nor was he permitted to leave the Paris airport and enter France. He soon became an international hot potato as his case bounced back and forth among officials in England, France and Belgium. At one point French authorities offered to allow him to reside in France, but Nasseri turned down the offer, reportedly because he wanted to get to his original destination, England. And so he stayed at Charles de Gaulle Airport for nearly 18 years. He left only in 2006, when his declining health required hospitalization.

1. Who claimed to have a life-changing revelation with a phrenology practitioner (a debunked science measuring skull bumps to predict traits) and "learned" he had an inventive talent?

  • Nikola Tesla
  • Alexander Graham Bell
  • Orville Wright
  • Thomas Edison

Thomas Edison claimed he had a life-changing revelation after one of the "phrenological Fowlers" felt his head bumps. "I never knew I had an inventive talent until Professor O.S. Fowler examined my head and told me so," he was quoted as saying in the September 1904 issue of The Phrenology Journal and Science of Health. "I was a stranger to myself until then."

  • Marx
  • Nietzsche
  • Socrates
  • Marcus Aurelius

Friedrich Wilhelm Nietzsche (who was famous for the quote "God is dead") was the son and grandson of Lutheran ministers. He was expected to follow their path, but the precocious young Nietzsche had his own ideas. And these were enormously influential in the 20th century.

3. Fact or myth: Dishwashers save a significant amount of water compared to hand washing.

Fact. Today's dishwashers only use 3-5 gallons to clean an entire load. Handwashing can use 4 gallons of water every two minutes. A standard ENERGY STAR certified dishwasher saves an average of 3,870 gallons (14,650 liters) of water over its lifetime. Plus, it only costs an average of $35 per year to operate.

  • Dog
  • Cat
  • Tortoise
  • Monkey

Two tortoises were sent on Zond 5, a Soviet spacecraft, in 1968 to circle the moon. Both tortoises survived the trek. Although each one lost about 10 percent of its body weight, they were found to be in good health overall. Caretakers also reported that the adventure didn't hurt their appetites; the creatures enjoyed some nutritious dinners after coming home.

5. What country is the United States most in debt to?

  • China
  • Taiwan
  • Japan
  • Canada

In 1989, New York real estate investor Seymour Durst spent $120,000 to erect a "National Debt Clock" in Times Square to track the exact amount of money that the U.S. federal government was borrowing to pay its bills. By June 2021, the upgraded clock — which can now display up to a quadrillion dollars — registered more than $28 trillion. The United States owes Japan  $1.2 trillion, as well as 6.2 trillion to itself in intragovernmental holdings.

6. True or false: During Victorian times, a "Marriage market" took place between January to June every year. During this time ladies and gents mingled under supervision to find a spouse.

True. People could only look for a spouse within their own social class and it was common for women to seek out the eldest son, as they kept the estate. The "marriage market" began in January and ended in June. If a young lady couldn't find a husband in three seasons, she could largely expect to spend her life as a spinster. Couples were never allowed to be alone with each other and would only converse in the presence of a chaperone. A gentleman would call on a lady at her family home to spend time together and determine each other's character.

1. Myth or fact: During a tornado you should open your windows to help equalize pressure and reduce flying debris.

Myth. When this theory was tested by researchers, they found that leaving windows open actually caused the force of the tornado to push up on the roof of the house, while the gusts of the twister lifted the roof. Open windows and doors, in other words, resulted in an airborne roof.

3. True or false: If a drone enters your property and hovers at a height 5 feet (1.5 meters) or less, you are legally allowed to shoot it in the United States.

False. You are not allowed to shoot at a drone. The FAA describes a drone as an aircraft and Title 18 of the U.S. Code prohibits you from shooting, wrecking or damaging one. You might be fined or even jailed. In case of a threat, contact your local police or law enforcement agency to tackle the issue.

4. How much ice cream does the average American consume each year?

  • 6 pounds (3 kilograms)
  • 23 pounds (10 kilograms)
  • 82 pounds (37 kilograms)

23 pounds (10 kilograms). Americans love their frozen desserts. About 6.4 billion pounds of ice cream and frozen yogurt were produced in the U.S. in 2019.

5. Tarrare, an 18th-century century French man with a truly insatiable appetite, was asked to swallow a box containing a note and deliver it across enemy lines. What was his reward for accepting this mission?

  • 12 gold coins (or 288 livres, equivalent to a 4-5 months worth of unskilled labor)
  • 30 pounds (13 kilograms) of bull's lungs and livers
  • Farmland and a few cattle
  • 100 gallons of wine

30 pounds (13 kilograms) of bull's lungs and livers. Tarrare's tale isn't for a weak stomach. Raw bull's lungs and livers were a rather tame meal in comparison to his other "food" choices. He readily ate anything that was put in front of him, from live animals to corpses, as well as inanimate objects like coins and corks. After crossing enemy lines with the box still inside him, he was captured and sentenced to hang. Only at the 11th hour did the Prussian general have mercy on Tarrare's soul and send him back to French lines with a warning.

6. True or false: Diamonds are the hardest naturally occurring minerals on earth.

False. Although diamond was the hardest material Mohs put on the scale, there are six materials that are now known to be harder, like wurtzite boron nitride or a pure lonsdaleite meteorite, but the other four are not naturally occurring.

1. By the time Robert Wadlow, the tallest man in history, was 18 months old, how much did he weigh? (Hint: 24 pounds or 11 kilograms is the average for that age)

  • 15 pounds (7 kilograms)
  • 24 pounds (11 kilograms)
  • 41 pounds (19 kilograms)
  • 62 pounds (28 kilograms)

At 6 months old, he weighed 30 pounds (13.6 kilograms) then 62 pounds (28 kilograms) by age 18 months. By 8, he was 6 feet, 2 inches (1.8 meters) tall and 195 pounds (88 kilograms). His two brothers and two sisters were all average in both height and weight.

2. True or false: The vast majority of appliances have plugs that have a hole in each prong.

True. There are three reasons for the holes. First, if you look at the contact wipers in the outlet, you would find that they have corresponding bumps on them, which help grip the plug prongs more firmly. Second, manufacturers can "lock-out" users by tying a plastic band through the holes and attach a message that requires them to do something before plugging in the device. Third, there is a small savings in raw materials (metal) for the manufacturer of the actual plug prong.

3. Where does the name WD-40 come from?

  • It was the 40th version of the formula that worked.
  • It was reported to have 40 uses at the time.
  • There are 40 ingredients in the formula.
  • The founder considered 40 to be his lucky number.

WD-40 was created in 1953 by Norman Larsen, an employee of the newly formed Rocket Chemical Company. It was produced specifically for use in the aerospace industry. The WD in the product's name stands for water displacement, while the 40 was added because it took the fledgling company 40 tries to perfect the formula.

4. Which country is more likely to use metal chopsticks than bamboo?

  • China
  • Japan
  • South Korea

Korean barbeque is extremely popular in its home country. It involves cooking meat on a grill that's built into the dining table itself. Customers cook their own meat and take it off the grill once it's cooked. Unlike bamboo, metal chopsticks won't burn when exposed to the heat or flame.

5. True or false: Newer vehicles with keyless (push button) ignitions are impossible to hot-wire.

True. These cars work more like computers. They unlock whenever the key fob is in the vicinity, and the ignition starts with a press or turn of a button. There's no ignition lock cylinder to bypass. These changes basically rendered the entire hot-wiring process obsolete. But that doesn't mean that your car is less likely to be stolen.

1. True or false: The British Royal line of succession will always go to the next male in line, even if there is an older sister.

False. Before the Succession to the Crown Act, passed in 2013, males were always given priority over females. However, the Act ended the system of "male primogeniture," so the monarchy is equally available to both sexes — the oldest child is now next in line for the throne, followed by the child next in age and so on. (This change applies only to those born after Oct. 28, 2011.)

3. True or false: Even though there were fewer drivers on the road in 2020 (due to COVID-19), there were more fatalities in 2020 than in 2019.

True. More people died in car crashes in 2019 — a 7.2 percent increase in fact. Early numbers indicate 38,680 people died on the road in 2020, which is the largest projected number since 2007. So if Americans drove so much less, why were there so many more fatalities on the roads? Three reasons: impaired driving, speeding and failure to wear a seat belt.

4. True or false: On hot summer days, tires are more likely to 'blow-out' if they're underinflated.

True. Car tires are more prone to blow-out when they are underinflated. When a car is driving down a road, the sidewalls of the tires are flexing (bending, grabbing the asphalt), which creates heat. If the tire pressure is correct, then the heat created is minimal. But if the tire pressure is low, then the sidewalls have to do a lot more flexing, and create a lot more heat. Add in the summer sun and eventually the bonds in an under-inflated tire can break down and you have a blowout.

6. In order to instigate an uprising against his ruler Persian King Darius I, how did Histiaeus (a Greek advisor) send a message to his son-in-law, Aristagoras?

  • He used urine as "invisible ink," which reveals itself over a flame.
  • He delivered a painting with an inscribed message on a concealed portion of the back.
  • He sent a normal message but italicized words to form a secret message.
  • He tattooed the message onto the head of the slave and allowed the hair to grow back, which was shaved upon arrival.

The adviser got his wish: Aristagoras stirred up the Ionian Revolt of 499 through 494 B.C.E. — Darius I ultimately prevailed, but the revolution catalyzed the Greco-Persian Wars (you know, the ones dramatized in the movie "300").

2. What's the difference between barbecuing and grilling?

  • They're the same thing.
  • Grilling is on a low fire, while barbecue is on a hot fire.
  • Barbecue is on a low slow fire, while grilling is hot and quick.

Barbecuing and grilling are often mistakenly thought to be the same thing but they're not. Barbecue takes place on a low fire for a long period of time ( a technique called "low and slow") while grilling refers to a quick cook on a hot fire.

3. True or false: Royalties earned by TV actors on reruns are typically a very stable income, as long as the show remains running.

False. The amount paid out decreases after each rerun — so by the 13th rerun, the amount has decreased to 5 percent of the original fee the actor was paid for her appearance in an episode. This 5 percent will be paid every time an episode is run forever.

Read more: Can a TV Actor Live Off Royalties Forever?

4. True or false: Most reality shows have clauses that do not allow contestants or competitors to speak negatively about the show, even after it's over.

True. Contestants may also not be able to disclose anything about their experience on the show either.  In 2010, contestants on "Survivor" faced a $5 million fine every time they broke the show's confidentiality agreement. And don't think you can negotiate such clauses away — unless, perhaps, you're a celebrity or have similar clout. The courts will typically uphold these contracts. So don't count on a sympathetic judge to rule in your favor if you suffer physically or mentally afterward, or are simply unhappy with your portrayal.

1. In 2017, approximately how many phone calls were made to 911 in the United States?

  • 900 thousand
  • 12 million
  • 240 million

A bit of history for you: Before 1968, there was no standard emergency number. People called the numbers of the nearest police station or fire department when they had an emergency. As far back as 1957, the National Association of Fire Chiefs recommended the use of a single number for reporting fires.

Related: Why Was 911 Chosen as the Emergency Phone Number?

2. True or false: Only audible noise — sounds within the range of human hearing — has the power to cause negative effects on the human body.

False. Research has linked ultrasound, which can penetrate and heat living tissue, with ailments such as dizziness, balance disturbances, tinnitus — a persistent ringing in the ears — and fatigue. Infrasound — inaudible low frequency sound — also can affect the human body.  If infrasound is the right frequency and sufficiently intense, according to neuroscientist Seth S. Horowitz, it could cause a person to see colored flashes or even experience breathing difficulties.

3. True or false: In an experiment where 5,000 fictitious resumés were submitted to "help wanted" ads in Chicago and Boston newspapers, resumes with whiter-sounding names (think Emily or Greg) received 50% more callbacks than stereotypical black names (like Lakisha and Jamal).

True. In a separate experiment, even white job applicants with criminal records received more callbacks (17 percent) for the same jobs than Black applicants with no criminal record (14 percent).

  • 17,000
  • 8,000
  • 600

Overshadowed by a global pandemic, the 2020-2021 flu season was little more than a blip on the radar. For a virus that killed about 22,000 people during the 2019-2020 flu season, and 34,000 the season before, the influenza virus infected slightly more than 2,000 and killed only 600 during the 2020-2021 season, according to the Centers for Disease Control and Prevention (CDC).

1. True or false: Rewilding is different from most conservation efforts in that it doesn't just look at saving one particular animal, instead it involves dozens if not hundreds of projects that aim to enable ecosystems to restore themselves.

True. There isn't one clear definition of rewilding. However, the general purpose is to restore the abundance and diversity of wildlife to a place. It's a large-scale restoration of nature to allow nature to eventually look after itself again.

4. When was the first practical dishwasher invented?

  • 1886
  • 1922
  • 1955
  • 1978

The first practical dishwashing machine was invented in 1886 by Josephine Cochran. Her company went on to become what we know today as KitchenAid. The dishwasher was operated by hand; using a crank a person could spray soapy water into wire compartments containing dishes. The dishwasher was adopted by hotels and large restaurants. It wasn't until the 1950s when dishwashers were sold to the general public.

5. True or false: One study found that during winter more than half of Southern California's homes featuring gas stoves had indoor pollutant levels exceeding safe limits. This can be mitigated substantially by always using a kitchen exhaust fan when cooking.

True. You've undoubtedly seen ominous smog that hangs over heavily polluted metropolitan areas. Now, imagine that your kitchen stovetop might create more pollution than some places that have famously filthy air. That's because cooking over high heat produces carbon monoxide, nitrogen dioxide, formaldehyde, fine particulate matter and other potentially dangerous byproducts. (Electric stoves don't produce carbon monoxide and only small amounts of nitrogen dioxide, though they do produce fine particulate matter.) Ducted hoods are the best solution to this problem, as they suck in contaminated air and then vent it to the building's exterior.

1. The most expensive car in the world sold for a whopping $48.4 million. What was the car manufacturer?

  • Ferrari
  • Mercedes-Benz
  • Duesenberg
  • Aston Martin

In 2018, RM Sotheby's sold a 1962 Ferrari 250 GTO for nearly $50 million. The car was estimated to bring in $45 million, so this huge price was not actually a shock when the hammer fell. Why is this old car worth so much? For one thing, it has matching numbers, which means the engine and the chassis originally came together from the Ferrari scuderia. There were only 36 built, and this was the third in that series. Legendary driver Phil Hill tested it in a race before it was sold to its first owner, who won races in it throughout the 1960s — without a single accident.

2. Myth or fact: If you feel symptoms after receiving a COVID-19 vaccine, that means that the vaccine is working well and you'll mount a stronger immune defense against the real virus.

Myth. The bottom line is you can't gauge how well the vaccine is working within your body based on what you can detect from the outside. Different people do mount stronger or weaker immune responses to a vaccine, but post-shot side effects won't tell you which you are. It's the second, adaptive immune response that helps your body gain vaccine immunity, not the inflammatory response that triggers those early aches and pains.

3. Many people have become accustomed to saying "gesundheit" when someone sneezes. The term comes from Germany and means:

  • "God bless"
  • "Health"
  • "Live long"
  • "Mercy"

The idea is that a sneeze typically precedes illness. It entered the English language in the early part of the 20th century, brought to the United States by German-speaking immigrants.

4. True or false: Restaurants in the U.S. are required to enforce "no shirt, no shoes, no service" by law in order to comply with health codes set by the U.S. Department of Health.

False. "Shirt and Shoes Required" signs never had anything to do with enforcing health codes, despite the fact that several early versions of the sign included the addendum, "By order of the Board of Health." There is no U.S. federal law that enforces this rule. However, business owners can still refuse to serve someone without a shirt or shoes. That is because they are allowed to enforce any dress code in their establishment, as long as it is not discriminatory.

5. What is a "minced oath?"

  • When you tell the truth, but omit important information in a dishonest way.
  • When you substitute a taboo word for a similar sounding word.
  • When someone is paid off to lie on the stand.

"Holy cow" for example is a "minced oath." It's when you substitute a kind of maybe similar-ish-sounding word for a taboo word. That's why we have "frickin" and "dang it" and "shizz." In this case, "cow" is probably a stand-in for "Christ" so the speaker wouldn't take the Lord's name in vain.

1. True or false: A federal ban exists in the United States that prevents slaughtering horses for human consumption.

False. No federal ban exists on slaughtering horses for human consumption, but many states have their own laws regarding horse slaughter and selling horse meat. The ban on slaughtering horses for meat "has become an annual fight" in Congress, according to USA Today. There is bipartisan support for banning it permanently, something the Humane Society of the United States supports but the American Veterinary Medical Association does not.

5. True or false: Hornets and wasps diverged around 40 million years ago on the evolutionary tree, and represent very distinct groups of species.

False. Hornets are just a kind of wasp, and wasp is a very broad term that covers many different species with different lifestyles.
