  • A busted motor mount

As this happens, the metal may become thinned out or warped in certain spots. When the brake pads grip the rotor at high speeds, these imperfections cause a rumbling in the brake pedal that's then transmitted to the steering wheel.

1. What defense mechanism do hagfish use to protect themselves against predators?

  • They secrete slime.
  • They wrap around their predators to strangle them.
  • They use their strong jaw.

"Hagfish their slime as a defense against gill-breathing predators, like sharks," explains Salisbury University physiologist Noah Bressman. "When a bites down on a hagfish, the hagfish contracts muscles surrounding their slime glands, causing them to secrete their slime exudate into the water. This concentration then rapidly expands into the fish's mouth, attaching to the gill arches. With the gills clogged, the fish may choke and suffocate from the slime, causing them to release the hagfish."

2. True or false: All Scottish families have their own unique tartan.

False. Just because you have a Scottish surname or can trace your genealogy back to Scotland, that doesn't mean that your family has its very own unique tartan. That's because those types of family tartans are only associated with certain Highland clans and not everybody's Scottish heritage traces back to the Scottish Highlands.

3. True or false: About one-third of people do not get goosebumps.

True. According to Mitchell Colver, an instructor of special topics at Utah State University, about two-thirds of people get goosebumps and the remaining one-third do not. One possible explanation is their personalities. Colver has found that people who are classified as being "open to experience" — one of the Big Five Personality Traits — are more likely to get goosebumps than people who are less open to experience. The reason? They're more apt to have a more deeply emotional reaction to new experiences.

4. Why is haggis, Scotland's national dish, banned in the U.S.?

  • It contains horse meat.
  • Making the dish requires the use of unpasteurized milk which is illegal in the U.S.
  • Livestock lungs cannot be used as food for humans in the U.S.
  • Haggis production involves inhumane treatment of animals.

The authentic version of haggis has been banned from import in the U.S. since 1971. This is because the U.S. Department of Agriculture decreed that livestock lungs cannot be used as food for humans because they can contain stomach fluid, which is a serious foodborne illness risk. (You can buy haggis in the U.S., albeit one made without the all-important sheep's lungs.)

1. Casu marzu is an illegal cheese made only on the island of Sardinia. Which live creature is in this cheese?

  • Termites
  • Baby wasps
  • Maggots
  • Caterpillars

Casu marzu, as we said, is a cheese made only on the island of Sardinia. The cheese starts out as a typical pecorino and when aged, cracks form, allowing for a special ingredient to enter the wheel — cheese skipper flies (Piophila casei). "While it ages in the open air, the cheese naturally dries out and cracks, which allows for a particular type of 'cheese fly' to climb in and lay eggs," Julia Birnbaum, cheese expert and founder of Philly Cheese School, says via email. When the eggs hatch, maggots squirm and wiggle in the cheese.
