Brain training with Three-Hint Quizzes! Idea prompts that feel great when you get the answer

cat

When it comes to natural enemies of mice, cats certainly fit the bill. Their fickle, hard-to-read personalities are part of their charm. Cats often chase small birds as well as mice. This is because their ancestor, the wildcat, preyed on small birds and mice in the mountains. It’s said that this behavior has been passed down to cats today.

bicycle

Bicycles are a convenient way to get around over short distances, aren’t they? There are various theories about where bicycles originated. Some say the world’s oldest bicycle was invented in Germany, while others point to Honjo City in Saitama Prefecture. Typically, bicycles have two wheels, but with training wheels even small children can ride. Seeing parents and children riding together is a heartwarming sight, isn’t it?

dinosaur

Dinosaurs that are no longer seen today are said to have gone extinct about 66 million years ago. Fossils and traces of dinosaurs have been found all over the world, and research has helped us understand this. Among the reasons proposed for the extinction of even the largest dinosaurs—some reaching up to 40 meters in length—the asteroid impact hypothesis is considered the most likely. There are also other hypotheses, such as volcanic activity and changes in the oceans. It might be interesting to look into it further.

Coffee

Coffee is a beverage whose distinctive bitterness is delicious. It seems that small children sometimes get curious about the coffee that adults drink so enjoyably. They may sniff the coffee and make a face as if to say it smells strange. Perhaps the appeal of coffee is something you come to understand when you grow up. The aroma of coffee brewed during work is also said to have relaxing effects and enhance concentration.

fireworks

From the clue “shines in the sky,” one might also think of stars, but stars can be seen all year round and they don’t make sounds. From those two hints, you can arrive at the correct answer: fireworks. The large bursts of fireworks blooming in the summer night sky are truly beautiful, aren’t they?

milk

It is said that milk began to be served in school lunches when an elementary school in Tokyo started the practice in 1920 (Taisho 9). Some people also say it began after the war. The long-standing practice of providing milk with school lunches has continued to this day, and milk is often served with school meals. In addition, it can be used in a variety of dishes and sweets, making it an indispensable drink in our daily lives.

Elevator

Elevators are convenient in buildings and apartment complexes when you want to go to higher or lower floors. You can move just by pressing the button for the floor you want, and it’s easy even when you’re carrying heavy luggage. Sometimes there’s a mirror installed on the back wall of the elevator car. Do you know what it’s for? It’s said to be installed so that people using wheelchairs can exit the elevator safely. When the car is crowded, they may have to exit backwards. The mirror is there to help them do so safely.
