The world's top ten brain-burning logic questionsThe world's top ten brain-burning logic questions were:
1. Pirate Divide
With five pirates, they managed to snatch 100 gold coins. They distributed the gold coins according to their levels:
- The most powerful pirate proposed a distribution plan, but it required more than half of the people to agree. Otherwise, they would be thrown into the sea to feed the sharks.
- The remaining four pirates were also distributed according to the same rules. More than half of them had to agree, or they would be thrown into the sea to feed the sharks.
- Every pirate was very smart and only considered their own interests.
- How should each pirate be distributed in order to maximize their own interests?
2. three Musketeers
The three musketeers were Aldos, Bordeaux, and Arames. "There's at least one knight among us," said Aldos. "There are only two knights among us," Bordeaux said. "Aldos and I are both knights," said Arames.
According to the above dialogue, can you tell how many knights are there among the three of them?
3. prisoner's dilemma
The police arrested two suspects, A and B, but there was not enough evidence to charge them. So the police imprisoned the suspects separately and met with the two of them separately. They provided the same options to both sides:
- If a person pleaded guilty and gave evidence against the other party (known as "betraying" the other party), and the other party remained silent, the person would be released immediately, and the silent person would be sentenced to 10 years in prison.
- If both of them remain silent (in the relevant jargon, they "cooperate" with each other), both of them will be sentenced to one year in prison.
- If both of them reported each other (betraying each other), they would be sentenced to eight years in prison.
- After A and B were separated, they went through the above choices.
The problem was:
- How would A and B choose?
- If A kept silent and B betrayed, what would happen?
- If both A and B reported each other, how many years would they be sentenced to?
4. Hanoi tower problem
The Tower of Hanoi was a puzzle toy from an ancient Indian legend. When Brahma created the world, he made three diamond pillars. On one of the pillars, there were 64 golden discs stacked in order of size from bottom to top. Brahma ordered Brahmin to place the disc on another pillar in order of size from the bottom. It was also stipulated that the small disk could not be enlarged, and only one disk could be moved between the three pillars at a time.
Q: How do I move the disc?
5. Infinite Monkey Theorems
If countless monkeys were to randomly type on countless keyboards for an infinite amount of time, then at some point, they would inevitably type out all the works of shakespeare.
The key here was "random" and "infinite".
Monkeys definitely wouldn't just happen to type out a great literary work because they didn't have that much time to try out all the possibilities. However, they were certain that they could play some parts of the works of William Shaw, as long as they were given enough time and opportunity.
According to the above theorem, can we assume that any random event must occur?
6. birthday paradox
Randomly pick a group of people, and two of them will have the same birthday (at least two people have the same birthday). If one knew that there were 366 days in a year, then the probability of two people having the same birthday would be more than 50%. If there were 365 days in a year, the probability of two people having the same birthday was 97%.
What was the probability of two people having the same birthday?
7. Monty Hall problem
The contestants would see three closed doors, one of which had a car behind it, and the door with the car behind it would win the car. The other two doors each had a goat hidden behind them. When the contestant chose a door but did not open it, the host opened one of the remaining two doors, revealing one of the goats. The host would then ask the contestant if they wanted to switch to another door that was still closed. The question was whether switching to another door would increase the contestant's chances of winning the car.
8. Schrodinger's cat
Schrodinger's Cat was a thought experiment on quantum mechanics. The content was: A cat was kept in a closed container containing a small amount of radium and helium. There was a chance that radium would decay. If radium decayed, it would trigger a mechanism to break the bottle filled with cyanidation, and the cat would die. If radium did not decay, the cat would survive. According to the theory of quantum mechanics, since radioactive radium was in a state of decay and no decay, cats should be in a state of dead cats and alive cats. This cat that was both dead and alive was the so-called Schrodinger's cat. However, it was impossible for a cat to be both dead and alive, so the results would only be known after the container was opened.
So, was the cat dead or alive?
9. Zeno's paradoxes
Achilles was a running hero in ancient Greek mythology. In the race between him and the tortoise, he was ten times faster than the tortoise. The tortoise ran 100 meters in front, and he chased after it, but he could not catch up with the tortoise. Because in the competition, the pursuer must first reach the starting point of the chased. When Achilles reached 100 meters, the tortoise had already climbed another 10 meters. Therefore, a new starting point was created. Achilles must continue to chase. When he reached the 10 meters that the tortoise had climbed, the tortoise had already climbed another 1 meter. Achilles could only chase that 1 meter. In this way, the tortoise could create an infinite number of starting points. It could always create a distance between itself and the starting point. No matter how small the distance was, as long as Achilles 'speed was 10 times that of the tortoise, he would never be able to catch up with the tortoise.
Then, could Achilles catch up with the tortoise?
10. Brain in a Vat
The "brain in a vat" was a hypothesis proposed by Hilary Putnam in 1981. The content was to take a brain out of a human body and place it into a tank filled with nutrient solution to maintain its basic survival. The brain's nerve endings were connected to a computer, and the computer transmitted information to the brain according to the program, so that the brain could maintain the illusion that everything was completely normal. To the brain, the world it lived in was a virtual world created by a computer.
Then, could the brain realize that it was in a virtual world?

How do you do the hypothesis for the logic questions in the NBA exam?The hypothesis of logic questions in the NBA exam usually needs to be reasonably constructed and proven. For details, you can refer to the following suggestions:
1. Confirm the question: the question to be answered clearly is, for example,"If A can cause B?" Or "Assuming B is true, can A be true?" Wait for the question.
2. Confirm the premises: specify the premises that need to be assumed in the question. These premises should be objective, clear, and need to be given in the question.
3. Choice of hypothesis: According to the question and premise, choose the most appropriate hypothesis to construct and prove reasonably.
4. Hypothesis verification: After completing the hypothesis, you need to verify the hypothesis. He could use logical reasoning, examples, and other methods to verify whether the hypothesis was correct.

It was important to note that logical rules and reasoning methods should be followed when constructing and proving assumptions, and the rigor and rationality of the assumptions should be ensured. At the same time, the hypothesis construction and argumentation requirements of the logic questions in the NBA exam were relatively high. It required the examinee to have a certain degree of logical reasoning and argumentation ability.
