General Knowledge & Fact Check Quiz

Shrimp have a dorsal heart located in their head/thorax region, not in their legs. Like other crustaceans, their circulatory system has a main heart that pumps hemolymph through their body. The heart is positioned above their digestive tract in the carapace.

This is a dangerous myth and could cause serious harm. Dog feces can contain harmful bacteria, parasites, and viruses that could lead to severe infections when applied to broken skin or insect bites. Proper treatment involves cleaning with soap and water, using antiseptics, and seeking medical attention if needed.

Commercial aircraft like the Boeing 747 are not designed or capable of sustained inverted flight. The fuel systems, hydraulic systems, and structural design all assume normal orientation. While fighter jets can fly upside down due to specialized design, a jumbo jet cannot maintain inverted flight safely.

On average, women's hearts beat faster than men's hearts. The typical resting heart rate for adult women is 78-82 beats per minute, while for adult men it's 70-72 beats per minute. This difference is partly due to women's generally smaller heart size, which requires more frequent contractions to pump the same amount of blood.

This is a myth. While gas compression occurs at depth due to increased water pressure, the gas in the digestive tract does compress but does not prevent flatulence. In fact, some divers report increased gas due to pressure changes affecting digestion. At depth, compressed gas would actually be smaller in volume than at the surface.

Polar bears live in the Arctic region (North Pole), while all penguin species are native to the Southern Hemisphere, primarily Antarctica and the southern coasts of South America, Africa, and Australia. These animals are on opposite sides of the planet and never encounter each other in the wild.

Paper was invented in China around 105 CE during the Han Dynasty, credited to Cai Lun. Egyptians used papyrus, which is made from thin strips of papyrus plant stems layered together, not from pulped fibers like true paper. Papyrus predates Chinese paper by thousands of years, but it's a different material and process.

This popular myth was debunked in 2002 by high school student Britney Gallivan, who successfully folded paper 12 times. She derived a mathematical formula showing that with long enough paper, it can be folded more than 7 times. The key is using very long, thin paper rather than standard letter-size sheets. The limitation is exponential growth in thickness, not an absolute rule.

The tongue is not the only muscle attached at only one end. While the tongue's genioglossus muscle is attached only at the chin end (with the other end free), other muscles like the sternocleidomastoid in the neck and some facial muscles also attach at only one end. The statement presents this as a unique characteristic when it's not.

This is pure nonsense with no scientific basis. In microgravity, carbonated beverages do behave differently - gas doesn't separate from liquid the same way, and liquid can form spheres. But a frozen pea would not 'explode' upon contact with Pepsi. The pea would slowly thaw, and the carbonation might cause some bubbling, but no explosive reaction would occur.

Human electricity consumption is negligible compared to natural sources of Earth's magnetic field. The geomagnetic field is generated by the geodynamo in Earth's outer core (convection of molten iron) and influenced by solar wind, cosmic rays, and ionospheric currents. All human electrical activity combined is orders of magnitude too small to affect planetary magnetic fields.

This claim is completely false - the 1930 World Cup in Uruguay used standard leather footballs, not monkey skulls. The final match between Uruguay and Argentina was played with a proper ball, and there's no historical evidence of such a bizarre practice. This seems to be an urban legend or fabricated fact.

This statistic is absurdly exaggerated. While hockey does carry dental risks and players do lose teeth, the idea that 70% of Canadian hockey players lose a tooth during a game has no basis in reality. Modern hockey has strict safety standards and many players wear full facial protection or mouthguards.

This statement is false - pumice is not the only rock that floats. Several other volcanic rocks with high vesicularity (gas bubble holes) can also float, including some types of scoria and other lightweight volcanic rocks. The key factor is density - rocks with enough air pockets can be less dense than water.

This claim is historically inaccurate. India has engaged in military interventions beyond its borders, including the 1971 intervention in East Pakistan (which led to the creation of Bangladesh) and historical expeditions by Indian empires like the Cholas. While India has generally been defensively oriented, the claim of zero invasions is factually incorrect.

This is false - a seasoned athlete's heart actually beats slower at rest, not faster. This is called 'athlete's heart' or athletic bradycardia. Regular cardiovascular training makes the heart more efficient, so it can pump more blood per beat. Athletes typically have resting heart rates of 40-60 bpm, compared to 70-80 bpm for non-athletes.
