Why did the man about to fight stop eating?
See the answer
Because I started losing weight.
When we hear the word “battle,” we tend to imagine an intense war. However, in this quiz, “battle” refers to a sports match. In sports like boxing and judo, which have weight classes, athletes need to restrict their diet and cut weight before a match, so this person stopped eating for that reason.
A certain kind woman won’t lend me her book. Why is that?
See the answer
Because it was an e-book
It's a very interesting riddle. Since e-books exist in the form of data, even a kind woman cannot physically lend them to someone. You can lend a paper book to a person, but e-books are difficult to lend, so she couldn’t lend it. The phrase “a kind woman won’t lend it to you” is also an easy point to get tripped up on.
Why was the weather all over the place, almost like extreme weather, even though it was within the same neighborhood?
See the answer
Because it was a child’s picture diary
During long vacations, you often see children putting off their homework. In this quiz, the answer is that the child slacked off on their diary and left many days unwritten, then hurriedly filled it in all at once, which led to dates and weather not matching up—even within the same neighborhood.
Ann stuck to all sorts of things, but she absolutely never stuck to her dad or mom. Why was that?
See the answer
Because Ann is the English article “an.”
A vowel sound refers to the sounds “a, i, u, e, o.” “An” can only be attached to words that begin with a vowel sound. Since neither “Papa” nor “Mama” starts with a vowel sound, “an” absolutely could not be attached to them.
A man was waiting in front of a house, but when the homeowner returned, he left. Why?
See the answer
Because the man was a delivery person.
If no one is home, delivery workers sometimes can’t hand over the package. In this case, once the homeowner returned and the package was delivered, the courier could go back with peace of mind. It can be hard to find the answer if you overthink it, but by picturing everyday situations, you can arrive at it easily.
Mr./Ms. A went enthusiastically to an interview but returned without taking it. Why?
See the answer
Because you seemed busy
Seeing a sign posted early in the day that read “Sold Out Today,” Ms. A realized that this shop was thriving. It seems she understood that customers come in from early hours and that it’s a busy place. Since Ms. A was looking for an easy, comfortable job, she decided it wasn’t what she was seeking after seeing the sign and went home without attending the interview.
A man who lives on the 10th floor of a building always gets off the elevator on the 7th floor and walks up the stairs the rest of the way. Why is that?
See the answer
Because I couldn't press the 10th-floor button.
Because the 10th-floor button in the elevator was installed high up, the short man couldn’t reach it and couldn’t press it. Therefore, he pressed the 7th-floor button, which was the closest reachable button to the 10th floor. That’s why he walked up the stairs from the 7th floor to the 10th floor.
