Let's take on a four-choice quiz that everyone can enjoy together!

kiwi

People tend to think of kiwifruit as sour, but there are sweet varieties these days, and it seems more children are coming to like kiwi. In fact, kiwi is a fruit from the Actinidiaceae family. Kiwi branches and roots contain matatabilactone and actinidine, just like silver vine (matatabi).

The way the fabric moves

It’s often thought that bulls go wild in response to the color red, but in fact, their vision is essentially monochrome, so they can’t distinguish colors. Bulls react to unfamiliar or moving objects as a way to protect themselves from predators, so by nature they become wary of a fluttering piece of cloth and charge at it. Therefore, the color of the cloth doesn’t matter; in bullfighting, red is used to excite the audience by evoking blood and danger.

110km

The Indo-Pacific sailfish can swim at an astonishing 110 km/h underwater! It’s even listed in the Guinness Book of World Records. Since the speed limit on highways is 100 km/h, that means it’s even faster. You could say it’s truly as fast as the blink of an eye.

Spider

Do you know the definition of an insect? Creatures called insects have bodies divided into three parts—head, thorax, and abdomen—and they have six legs. Spiders, having eight legs, don’t fit the definition of insects. Since they look similar, many people may have thought they were insects.

sugar

Slugs are creatures whose bodies are largely composed of water and are vulnerable to osmotic pressure. Like salt, sugar has the property of drawing out moisture. When sprinkled on a slug, it rapidly extracts water from its body, causing the slug to shrivel and appear to dissolve. Although not as potent as salt, sugar acts on the same principle and is therefore also very dangerous to slugs.
