Common Myths and Misconceptions Quiz

This statistic appears to be an unverified trivia fact often cited without reliable source data. While choking accidents do occur, the specific claim of '100 people choke on ball-point pens annually' lacks credible documentation from health or safety organizations. It's likely exaggerated or fabricated.

Some snail species can enter extended periods of dormancy (estivation or hibernation) lasting 1-3 years to survive drought or cold conditions. However, 'ten years' is an exaggeration beyond documented scientific records for most snail species. The claim is overstated.

Several U.S. Presidents were only children, including Franklin D. Roosevelt, Gerald Ford, and Bill Clinton (though Clinton had a half-brother later). The statement that 'no president was an only child' is factually incorrect.

Pumice floats due to trapped gas bubbles from volcanic formation, but it's NOT the only floating rock. Scoria and other highly vesicular volcanic rocks also float. The claim of exclusivity is incorrect.

The belief that goldfish have a 3-second memory is a myth. Scientific research has shown that goldfish can remember things for months, not minutes. They can be trained to respond to cues and have much longer memory spans than commonly believed.

Leonardo da Vinci did sketch a parachute design in the late 15th century, but he did not invent it in 1515. The first practical parachute was developed much later by Sebastien Lenormand in 1783. The date and attribution are incorrect.

Onions do have distinct flavor - they contain sulfur compounds that create their characteristic taste, not just aroma. The flavor comes from these compounds, while the smell is from volatile sulfur compounds released when cut. The statement is false as claimed.

Balinese naming tradition does use these four names based on birth order, but there are additional names beyond these four (like 'Pan' or 'Ketut' being used for 5th+ children in some regions). The 'only' makes the statement false.

Olive trees are long-lived, but the oldest confirmed olive trees are around 2000-3000 years old, not 15000. While some unverified claims suggest extreme ages, the 15000-year figure is not scientifically supported. The statement is false as claimed.
