I cried countless students in the exam

Chapter 35 Questions stump everyone! (Please collect and ask for a recommendation ticket!)

In the Scottish Flirt Hotel.

After Shen Ping saw the comments on Weibo, he smiled slightly and continued to ask the second question.

Now here’s another very simple question:
"A hundred years ago, two scientists studied the contribution of ribonucleic acid to catalytic performance..."

Weibo netizens are excited, this is very simple.

"Biology question!"

“Ask about the effect of RNA? Or something else?”

"If it wasn't for these questions, there would be no need for this question."

"I'm already preparing to answer the question. This question is too simple. You can even know it with your eyes closed."

However, when the four choices were made, everyone was stunned.

Q: Who is this scientist?
A: Sumner;

B: Cech;
C: Charles Robert Darwin;

D: Ultraman. "

I go!

Netizens are speechless!

"Multiple choice? And Ultraman?"

"I'll go to your sister's Ultraman!"

"It's agreed to ask about the effect of ribonucleic acid!"

"Co-authoring this is such a funny question!"

"Shen Ping, you are too bad!"

"Ultraman is busy fighting monsters, how can he have time to study ribonucleic acid!"

Netizens are complaining non-stop!

But in the next minute, Shen Ping's third question came out.

Topic: Known positive integers satisfy the condition: For any positive integer n, randomly select several numbers from the set {a1, a2, ..., an} without repetition, and the absolute value of the numbers obtained after addition and subtraction between these numbers The values ​​are positive integers that are different from each other, and these positive integers together with a1, a2, ..., an happen to be a set of all natural numbers from 1 to Sn, where Sn is the sum of the first n items of the sequence {an}.

Find: (1) find the value of a1, a2;
(2) Find the general term formula of the sequence {an}.

Netizens vomited blood again and again.

"This question has changed too quickly! The front foot biology question has now become a math question again!"

"Why does your sister still have to consider the general term formula!"

"Ghost knows how to solve this!"

"This is totally incomprehensible!"

Immediately, Shen Ping gave another question.

Topic: A long time ago, someone died, and the inheritance was only 19 cows, leaving a will.The three sons distribute the estate according to the will, and there are two rules.0.5. The eldest son is assigned 0.25, the second son is assigned 0.2, and the third son is assigned [-].Second, the cows must be alive!

Topic requirements: Please make a reasonable distribution according to the inheritance!

With the experience of making questions before, the netizens are also smart, and they no longer want to complain about Shen Ping like a fool, but wait for Shen Ping to finish all the questions before they continue to complain!

The last question is out!
Prove: Is tan1° a rational number?
Weibo netizens: "???"

"Rational numbers?"

"If it is reasonable, it is reasonable, if it is not reasonable, it is not reasonable. Let me prove it!"

"How the hell do I know if tan1° has a rational number!"

At this moment, Weibo netizens all reacted. At the beginning, when they saw Shen Ping saying that there would be rewards for the questions, they ran over excitedly, thinking that after getting the rewards, the questions they posed could also be included in the exam papers. I gave the students some questions, but now that I came back to my senses, Shen Ping had been holding back bad intentions from the very beginning, and he never planned to let them all pass. What kind of monster problem is this!

"Damn it, Shen Ping, you are too ruthless!"

"It's really cruel!'

"Who knows the answers to these questions!"

"Where is the first time to draw a lottery, just cheat the netizens!"

All Weibo netizens are unwilling!

Shen Ping smiled slightly, and said lightly: "Oh, I accidentally finished all the questions, can anyone answer them?"

Weibo netizens are unwilling!
"You didn't intend to let us get the reward from the beginning!"

"Shen Ping, you bastard, I will never live with you in this life!"

"That's right! If you lose the revenge of the reward, you will be at stake in this life!"

"These questions are simply not something that high school students can answer!"

"I'm sure, how can high school students solve all kinds of difficult problems! This guy is deliberately making things difficult for the students and making them fail!"

No one imagined to solve it any more, and got the final reward, and all of them ran over to complain about Shen Ping!

Shen Ping smiled slightly: "Since I have passed these test questions, it means that the knowledge points of the second year of high school will definitely not exceed the outline."

Weibo netizens spray non-stop!
"You fart you!"

"A sophomore in high school, this is definitely beyond the knowledge points of a sophomore in high school!"

"You're going to die like a duck!"

Even Ding Yulan from No. [-] High School in Beijing complained speechlessly: "Speechless, this is not a sophomore's knowledge point, this is clearly deliberately embarrassing netizens!"

No one believed that this was a sophomore's knowledge point, and they all thought that Shen Ping was deliberately deceiving people.

In the next second, Shen Ping actually gave an answer! "

The first is the first question about the three northeastern provinces:
Geographic location: The three provinces in Northeast China are important intermediate stations and contact points of the land bridge with the shortest mileage between Northeast Asia and Europe, and have significant geographical advantages. At present, the Party Central Committee incorporates "revitalizing the old industrial base in Northeast China" into the strategic layout of China's modernization drive .

Climate: It belongs to the continental monsoon climate, with four distinct seasons and the same period of rain and heat. The terrain is dominated by mountains, plains, and rivers. The distribution of Changbai Mountains and the Great and Small Khingan Mountains are important natural barriers for the Northeast ecosystem; the Sanjiang Plain, Songnen Plain, Liaohe Plain, soil Fertile, deep soil; Songhua River, East Liao River, West Liao River, Yalu River and other major rivers originate here, with huge economic and ecological value.

Resources: It also has important timber and mineral production bases in my country, and is rich in wild animal and plant resources. It is known as the "industrial cradle" of New China.

Industrial Status: The major industrial projects in steel, energy, chemical industry, heavy machinery, automobile, shipbuilding, aircraft, military industry and other major industrial projects in the three northeastern provinces have laid the initial foundation for China's industrialization.

Education: The three northeastern provinces are home to higher education institutions and scientific research institutes, with strong scientific research strength. The region has obvious advantages in knowledge reserve, intelligence density, and technology industry. Every [-] people have professional and technical personnel in state-owned enterprises and institutions, and college students rank among the top No. [-] in the country.

The answer was successfully answered!

Weibo netizens are confused!

The students are dumbfounded!

Parents of students are stunned!

Even Ding Yulan, director of political education at the No. [-] high school in Beijing, was confused!

The second question: Regarding the scientist of RNA, the correct answer is Altman.His discovery of the catalytic activity of ribonucleic acid (RNA) revolutionized two areas of biology: it not only corrected the long-standing conventional wisdom that all enzymes are proteins, but it also had implications for the question of the origin of life. Need to know from different angles!

Continue to answer: The problem of inheritance distribution is a very simple elementary school problem: the three natural numbers of a, b, and c satisfy a+b+c=19, a/19≥0.5, b/19≥0.25, c/19≥0.02, so a=10, b=5, c=4.All three sons received more than the proportion of the will, and all the cattle are live!

The last question, is the argument that tan1° is a rational number?
Shen Ping smiled and replied: "Who told you that it's not easy to prove?

First, clarify whether the quotient of two rational numbers is a rational number and use proof by contradiction.

Assuming tan1° is a rational number,

那么tan2°=tan(1°+1°)=(tan1°+tan1°)/(1-(tan1°)，

Then it can be known from the assumption that tan2° is a rational number,

Similarly, tan3°=tan(1°+2°) is also a rational number.
It is assumed that tan30° is also a rational number, and tan30°=√3/3 is obviously an irrational number, a contradiction!
So tan1° is an irrational number!

Following Shen Ping's answer, Ding Yulan was shocked, his students and fans were shocked, even Shen Ping's fans were shocked!

"Damn it, it's that simple?!"

"The world of Xueba... is really kneeling down!

"Are all math teachers today top academics? It's terrible!"

"Mr. Xiao Shen, you are too powerful!"

"I'm absolutely in admiration! The King of Exam Questions is the King of Exam Questions! The way of thinking about the questions is completely different from other coquettish sluts. It always seems difficult, but it's actually very simple!"

After the above test questions plus answers appeared, seven to eight thousand people were attracted to watch it in a short period of time. The people who eat melons were shocked!
