The questions of reasoning continue endlessly.
As we continue to solve these endless puzzles, our brains become activated.
From one fact, we infer related facts, logically trace causal relationships, and creatively reconstruct situations that could have led to such an event.
That's the beauty of reasoning.
From easy puzzles to detective puzzles that challenge you to uncover the truth of a given situation, this book will keep your brain busy.

Everyone is born with infinite potential, like a blank sheet of paper.
And as I live each day, I sketch and color on that piece of paper.
As people go through this process, they each develop their own way of thinking, and they tend to become fixated on one way of solving a problem.

A strange experience
A man slipped and fell while exploring the mountains.
Before he slipped, he was 45 meters below the summit, but after he slipped, he was at the top of the mountain.
He didn't walk to the top, nor did his comrades pull him to the top.
How could he have reached the top of the mountain after slipping from the middle of the mountain?
(proviso)
1.
The mountain he fell from and the mountain he climbed to the top are the same mountain, and he was originally below the top.
2.
He didn't rely on things like balloons filled with lighter-than-air gases like hydrogen or helium.
3.
There are no ropes or pulleys or anything like that.
4.
There was no updraft either.

Hitting the target
One morning, twins Larry and Pete drew a large target on the barn door and played with it, hitting it with a baseball.
But the barn door soon began to break, and if I did any more, I was sure to get scolded by my parents.
After much thought, the twins came up with a way to have fun without getting scolded by their parents.
After throwing the ball for hours, they counted every point accurately, and the surroundings were completely untainted.
What happened?
(proviso)
1.
The ball was not painted or mud was applied.
2.
The ball didn't bounce.
3.
Larry and Pete had to clean up the yard before playing ball, which was their greatest pleasure.
4.
The kids weren't messy.
