It is known from the known conditions.

Ms. Peng teaches 2 of them History, Mathematics, Physics, and English.

Mr. Zhang teaches Physical Education, History, Biology, Physics and 2 of them.

Start the exclusion. Teacher Zhang is the youngest, and the age of the biology teacher is greater than that of the mathematics teacher, but Teacher Zhang does not teach biology, and Teacher Zhang teaches 2 of them: physical education, history, and physics.

Because the physical education and physics teachers are 2 people, Mr. Zhang must teach history.

Exclude. Ms. Peng teaches Mathematics, Physics, and English 2 of them.

No one on it teaches biology so.

Teacher Zhao teaches biology.

Then exclude. Teacher Peng went to work with the biology teacher and the physical education teacher.

Teacher Zhang teaches physical education.

So Mr. Zhang teaches physical education history.

Ms. Peng teaches Mathematics, Physics, and English 2 of them.

Teacher Zhao teaches biology.

Then exclude. Ms. Zhang, along with her English teacher and math teacher, often goes to play volleyball together.

Teacher Peng definitely teaches physics.

Ultimate exclusion. The age of the biology teacher is greater than that of the math teacher.

Biology teachers don't teach math.

That's only Mr. Peng.

Teacher Peng teaches Mathematics and Physics.

Teacher Zhao teaches Biology English.

Teacher Zhang teaches physical education history.

The answer upstairs is yes, but the logic doesn't have to be that.

The biology teacher and the PE teacher may be the same person.

My other answer.

Zhang: History teacher, physics teacher.

Zhao: Biology teacher and physical education teacher.

Peng: Math teacher, English teacher.

Besides, if you rank by last name, the answer upstairs does not match "the physics teacher and the physical education teacher are neighbors".

Teacher Zhang: Physical Education History.

Teacher Zhao: Mathematics and Biology.

Ms. Peng: Physics English.

1. Divergent thinking training questions **Fruits and books.

There is a law in one country that only allows for time-limited and perishable commodities such as fruits on Sundays, and it is against the law to violate commodities such as books that will not lose their utility in the short term. So what should be done to legally sell both items on Sunday?

Answer: Stores can increase the price of fruit and give away some books for every purchase.

Pass the canyon in seconds.

If you get to this level, I have to admit that you are very clever, a river separates a canyon with a log (which can hold 2 people) through the canyon. A group of friends is on the left side of the canyon, there is another puzzle, the torch can only last 30 seconds, you have to get everyone through the canyon, it should be noted that if the torch reaches the other side of the canyon, someone must send the torch back, the number above the character's head is the time it takes them to cross the canyon. As shown in the figure below.

Answer: No, it should be 1 and 12 go first, and then 8 come up, considering that it can't be overtaken, and it takes 12 seconds to share. Then 1 goes to pick up 6, which takes 13 seconds. At 14 seconds, 3 goes up again and arrives with 6 in 19 seconds.

3. Cat and mouse math puzzles.

A cat spotted a mouse running 10 paces ahead of it, and the cat gave chase. The cat has a big step, it runs a distance of 5 steps, and the mouse runs 9 steps. But the frequency of the mouse is fast, and the cat can run 3 steps in the time it takes for the cat to run 2 steps.

Excuse me: At this rate, can a cat catch up with a mouse? If so, how many steps it has to run to catch up.

Answer: Yes, you have to run 60 steps to catch up with the mouse.

4. Cut the cake into two equal pieces.

There is a rectangular cake and the rectangular piece is cut off (random size and position), how can you cut the rest of the cake into two pieces of equal size with a straight knife?

Answer: Line the center of the whole cake with the center of the piece of cake that was cut off. This method also works for cubes.

Please note that the size and position of the cake you cut is arbitrary, and don't think about how you cut your birthday cake and think outside the circle.

5. Throw eggs to calculate the floors that will not break.

Eggs can be very brittle or unusually tough. This means that if you drop an egg on layer 1, the egg may shatter, and if you drop an egg from layer 100, the egg may be unharmed. These two eggs are exactly the same.

You need to calculate, from which floor will the egg not break? The question is, how many throws are there to ensure that level is found? (During the whole process, you are only allowed to break a maximum of two eggs, and if you break three eggs, you will fail the mission).

Answer: Actually, there are many strategies to solve this problem. 1.

One egg is enough, try from the first floor, the average number of times. 2.Divide the search, and then start the trial from the first floor, and the average number of times is non-solution.

But when there are enough eggs, there is a solution. 3.There are other strategies.
