[For Seniors] Popular Brain Training & Recreation Quizzes (91–100)
Among stew, fried eggs, pan-fried dumplings, and steak, which one is the odd one out?
It’s all food, so at first glance it seems like there’s no odd one out! The answer to “Which is the odd one out among stew, fried eggs, pan-fried dumplings, and steak?” is stew, which is a simmered dish.
Whether you can answer might depend on how well you understand the cooking methods for each item on the table.
Some people might choose “fried eggs,” using the criterion of “contains meat,” since fried eggs don’t use meat! The fun of odd-one-out puzzles is that you can think from many different perspectives.
Scissors that have become dull can be revived by cutting something found in a household kitchen. What is that “something?”
Scissors are stationery that everyone uses daily, but their sharpness inevitably dulls over time.
However, even dulled scissors can be easily revived just by cutting a common household item.
The hint is something from the kitchen: it’s made of metal, yet it can be cut with scissors—this should make it clear.
The answer is aluminum foil.
It’s said that a phenomenon occurs where the aluminum compensates for the worn parts of the scissors.
Since the effect is only temporary, it’s good to remember that properly sharpening them with tools is a more reliable solution.

There are four prefecture names that contain the names of animals. Which ones are they?
This is a simple quiz where you think of prefecture names that include animal names.
You probably know all of these places, so the key is how quickly the prefecture names come to mind.
If you go through them in order, you should be able to arrive at some of them, but if you get stuck, use each area as a hint.
The answers are Gunma, Tottori, Kumamoto, and Kagoshima.
It could be fun to reminisce about your memories of each place as well.
In prehistoric times, very few people got cavities. Why was that?
It’s surprising to think that our human ancestors, primitive people, didn’t have cavities, isn’t it? How could that be in a time without toothbrushes or toothpaste? The hint lies in the foods they ate back then.
The answer is that they only had hard foods.
Hard foods naturally increase the number of times you chew, which stimulates plenty of saliva, helping wash away bacteria and the like.
In contrast, in modern times, the increase in soft foods makes it easier for food to get stuck between teeth, and because we chew far fewer times, saliva production has greatly decreased, making us much more prone to cavities.
Besides salt, what seasoning, when sprinkled on a slug, would make it shrink?
Slugs that appear on rainy days.
Everyone knows they shrivel up when you sprinkle salt on them.
In fact, there’s another seasoning that makes them shrink when sprinkled: sugar.
The mechanism is the same as with salt—water is drawn out of the slug’s body.
However, with sugar it’s said to take about six times longer to fully shrivel than with salt.
If you want to learn more, check out videos of actual experiments.
That said, it does feel a bit sad.
Ichiro, a former professional baseball player who also excelled in the Major Leagues. He has two brothers; is he the older or the younger son?
Ichiro Suzuki, known simply as Ichiro, made a tremendous impact not only in Japan but also in Major League Baseball in the United States.
Although he retired in 2019 to much regret, his achievements remain etched in many people’s memories.
Ichiro actually has a sibling, but is he the older or younger brother? From his name, you might think he’s the firstborn, but the answer is that he’s the younger brother! It’s the kind of question many people might get wrong, so it could be fun to pose the same quiz to someone after this.
By the way, his older brother’s name also includes the character for “one” (一).
What are the buttons on the sleeves of school uniforms and suits for?
The buttons on the sleeves of jackets, like those on school uniforms and suits, may seem to serve little purpose—but why are they there? The answer is: to keep people from wiping their noses on their sleeves.
One theory says it began during Napoleon’s Russian campaign, when, unable to bear the sight of soldiers shivering in the cold and wiping their noses on their uniform sleeves, buttons were added.
There are also theories that they were meant to make it easier to open the cuffs and roll up the sleeves, or that they serve a purely decorative purpose.
In any case, it’s fun to ponder the history behind them.
