"Shen Qi, please look at the question. Sun Erxiong pointed to the big screen.

Switching to new questions on the screen, whether ordinary or excellent, students have to take a general knowledge test when they come to the Peking University Mathematics Camp.

The screen reads: "Which of the following four routes passes through the Papal Meridian: London-Mumbai, London-Hong Kong, London-New York, London-Rio de Janeiro?"

"Shen Qi, please give your answer. Sun Erxiong asked.

"Hmm......" Shen Qi stared at the screen and fell into deep thought, this general knowledge test question was only a simple sentence, but it contained a huge amount of information.

I've been to London, it's located at 0 degrees east longitude, and the Greenwich Observatory is located in London.

Mumbai is an Indian port, and everyone knows where Hong Kong is, so it sets sail from London to Mumbai and Hong Kong, and the ship goes east.

New York is in the United States, Rio is in Brazil, and the ship sails west from London across the Atlantic Ocean to New York and Rio.

So the most critical question is, where is the papal meridian located?

The meridian is also the meridian, and today's prime meridian passes through Greenwich, London, England, and Greenwich Mean Time is known as Standard Time.

The papal meridian should be a prime meridian that has existed in history, with the Greenwich meridian as a reference line, where is the longitude of the papal meridian?

This general knowledge question is not only related to geography, but also history.

"Shen Qi, have you thought about it?" asked Sun Erxiong.

"I ...... Think about it. Shen Qi quickly calculated in his mind, using the method of elimination, to pull a meridian on the world map that can move east-west, set it as the Pope's meridian, and the starting point is London, and it will move eastward, if it passes through Hong Kong, it will first pass through Mumbai. It moves westward, passing through New York and Rio. Therefore, Mumbai and Rio can be excluded, and Hong Kong and New York can choose either.

"My answer is that the London-New York route passes through the Papal Meridian. Shen Qi gave the answer, when the Pope ruled Europe, it seems that the Western colonists had not invaded the East, right?

Sun Erxiong nodded: "Historically, this meridian at 46 degrees west longitude is called the Pope's meridian, so only the London-New York route continues westward after passing through 46 degrees west longitude. Congratulations Shen Qi, the answer is correct, please sit down. ”

"The common sense of Peking University is not simple. Zhou Yu'an sighed that generalists who know astronomy, geography, and the past and the present, and the academic frontier may be able to make a difference in Peking University.

"Zhou Yu'an. Sun Erxiong pointed to Zhou Yu'an this time and asked a common-sense question about poetry.

Who is the author of the poem "The spring tide brings rain and the evening is urgent, and the wild ferry is self-averse"?

Li Bai, Du Fu, Luo Binwang, Li Shangyin, and Wei Yingwu choose one of the five.

Zhou Yu'an was blind to a Wei Yingwu, he had heard of the previous four poets, but he didn't know who Wei Yingwu was, so he chose Wei Yingwu.

"That's right, Zhou Yu'an, please sit down. Next, I would like to ask Ou Ye to introduce himself. ”

The only girl in the math camp stood up, with her long straight black hair and very white skin, even pale. Her facial features are exquisite, her eye sockets are slightly inverted, her lips are thin, and her lips are bright red, red and a little purple.

"Look closely, the only girl in our camp looks a bit like ...... Zombies?" Zhou Yu'an shuddered inexplicably.

"It's kind of like. Shen Qi admitted that he couldn't say that this girl was not good-looking, she probably belonged to the dark fairy tale girl.

The girl's voice was a little hoarse: "My name is Ou Ye, Ou is Ou of Euler, and Ye is Ye of Fourier." Thank you. "I gave a very brief introduction to myself, and I didn't mention where I came from, what awards I had won, or what my interests and specialties were.

"Ouye, good name!" Sun Erxiong was full of praise.

Zhou Yu'an: "Oh-yes?"

Shen Qi couldn't help but glance at her sister more: "Ou of Euler, Ye of Fourier, Ou Ye, this name is too good, she may be destined to learn mathematics." ”

Zhou Yu'an: "Cut, if you say that, am I destined to be the landlord?"

Shen Qi smiled: "Yes, Zhou Papi, you are the most picky boy I have ever seen." ”

After Ouye introduced herself, she took a general knowledge test, a general knowledge question about biology, and she quickly gave the correct answer.

Not long after, all 26 students in the camp were introduced, and everyone had a preliminary understanding of each other.

"Okay, we already know each other, and as expected, you will become fellow students of Peking University in September next year. Carrying a gun together, sharing a window together, this is the strongest friendship, and they are all fate, classmates. Sun Erxiong said enthusiastically.

"According to the practice of Peking University, the general knowledge test of our mathematics camp has ended, and the next step will be a professional test, yes, to test your best subject --- mathematics. I believe you can't wait. Sun Erxiong said lightly, "There will be a score statistics in the mathematics major test, which is also a routine, don't be nervous if it's okay." Look at the big screen. ”

"Sure enough......" Zhou Yu'an became nervous.

"The grades are counted out in order to divide the classes when you are officially in college?" Shen Qi had already seen through everything and was not shocked.

A new topic is projected on the big screen:

"In a game of fighting the landlord endgame, the cards in the hands of the landlord, farmer A, and farmer B are as follows. ”

"Landlords: 2, K, Q, J, 10, 9, 8, 8, 6, 6, 5, 5, 3, 3, 3, 3, 7, 7, 7, 7. ”

"Farmer A: Big King, Little Wang, 2, A, K, Q, J, 10, Q, J, 10, 9, 8, 5, 5, 4, 4. ”

"Farmer B: 2, 2, A, A, A, K, K, Q, J, 10, 9, 9, 8, 6, 6, 4, 4. ”

The topic is gone here.

All 26 students, including Shen Qi, stared at the projection screen intently.

Although I don't know what specific questions instructor Sun Erxiong wants to ask, the students who can sit here are all smart people, at least in the field of mathematics.

The students analyzed the conditions given by the questions in various mathematical ways in their hearts, and the classroom was silent and silent.

Sun Erxiong gave 5 seconds for the students to analyze the questions, and then broke the silence: "Please listen to the questions, pay attention, I will only ask the questions once." The question is, if all three players are cards open, and it is the landlord's turn to play cards without playing the wrong cards, who will be the first to play all the cards in their hands?

"This is the rush to answer the setting, students who calculate the results, please raise your hand, I will give you another 5 seconds to calculate the result, and after 5 seconds, if no one raises their hand, all will be judged 0 points!" Sun Erxiong suddenly became serious.

All the students were shocked, and anyone could fight the landlord, but to calculate the result in such a short time, it required extremely strong memory, calculation and deduction ability.

5 seconds passed quickly.

Brush!

Brush!

Two men raised their hands almost at the same time.

Shen Qi and Ou Ye.

Sun Erxiong hesitated for a second and then made a choice: "Lady first, Ouye, you answer first." ”

Ou Ye said three words lightly: "The landlord wins." ”

Shen Qi was a little annoyed, the result of his mental arithmetic was that the landlord was the first to finish playing the cards, and he raised his hand half a beat slowly. In fact, it is impossible to tell whether it is fast or slow, and it is difficult to tell which hand is raised first between Shen Qi and Ou Ye.

Sun Erxiong nodded: "Ou Ye answered correctly, 10 points, everyone else got 0 points, next question!"
