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.)
2. Google continues to be the top search engine in 2021 with a whopping 92.2 percent of the worldwide market share. What company is the distant runner up?
- China's Baidu
Far behind Google is Bing (8 percent), China's Baidu (7.3 percent) and Yahoo (3.4 percent).
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.

5. A 2012 study by University of Michigan researchers found that about _____ out of 10 New York City residents were chronically exposed to levels of noise that were high enough to harm their hearing.
Luckily, hearing aid technology is improving.
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").
