Kanji Quiz Part 1

[Kanji Quiz] Vol. 1! Give your brain a good workout!
Kanji Quiz Part 1

It was a Japanese language question, but maybe because I’ve had fewer chances to actually write kanji with a pen, I couldn’t answer it at all.

Do elementary school students answer questions like this smoothly? Thinking about that makes me really respect them, and it makes me feel that it’s wrong to dismiss them just because they’re children.

Precisely because we live in a digital society, it might become an era in which analog things like kanji become all the more important.

Kanji Quiz, Part 2

This time it’s not just arithmetic problems; it’s a Japanese language (kokugo) problem.

There are six questions in total.

As an adult, can you get them right? When you’re a child, if you’re interested, it seems like you can memorize as much as you want, so I think having a variety of experiences in childhood might be important.

As of 2018, AI hasn’t yet permeated society, but what will society be like from here on?

[Math Quiz] Using 4-minute and 7-minute hourglasses, measure 9 minutes.

It’s a simple yet tricky puzzle: using a 4-minute and a 7-minute hourglass, measure 9 minutes.

If you just use the 4-minute and 7-minute hourglasses, a total of 11 minutes would pass.

So the key to this problem is how to measure 7 minutes.

For those who are having trouble finding the answer, here’s a hint.

If you flip both the 4-minute and 7-minute hourglasses at the same time, the 4-minute hourglass will run out first.

At that point, the 7-minute hourglass will have 3 minutes’ worth of sand remaining.
