Wang Xueba System

"Let's start today's competition. The questions are randomly selected from the prescribed subjects, which means that it may be the test questions of any subject."

"Repeat the rules: This competition will randomly select questions from the question bank determined by the Education Bureau. After the questions are selected, both parties will start to answer the questions. One point will be awarded for correct answers within the specified time. No points will be awarded for unanswered questions. If you answer If they make a mistake, one point will be deducted. If both players answer the question correctly within the specified time, the team with the fastest answer will get one point. Finally, the total score will be calculated, and the side with the highest total score will win.”

"Next, start drawing the first question, please look at the big screen."

The host looked back at the big screen behind him.I saw a huge roulette appeared on the big screen, and on the roulette were the question numbers of each question.The moment the host's voice fell, it began to spin rapidly, and the numbers on the turntable were so fast that they could not be seen clearly.

"Stop!" The host gave an order after waiting for a while.

The wheel stopped spinning quickly, and the pointer stopped on the number "98".

"Okay, now we see that the questions have been extracted. Now the big screen shows the answer time and question type. The answer time is 5 minutes. The questions are multiple-choice questions. Please get ready, and start answering the questions immediately."

"Please see the question: Let the set a={1, 2, m}, where m is a real number, let b={a?丨a∈a}, c=aub, if the sum of all elements of c is 6, then c The product of all the elements of is _______”

"a.8"

"b.-8"

"c.10"

"d.-10"

"Timing begins."

As the host's voice fell, a countdown began to appear on the top of the big screen:

04:59

Because today is Saturday, and because of the vigorous publicity of the top five schools, many students, teachers, and parents were sitting in front of the TV to watch the competition.

Students with good grades will naturally look at the competition questions this time, as well as the gap between themselves and the top students, and students with poor grades will naturally come to watch the excitement.

Teachers and parents naturally want to see which school's contestants can survive the final victory.

When the question came out, some high school seniors who were "top-ranked" in various schools sitting in front of the TV all exclaimed in unison: "What kind of question is this? Have you learned this stuff in high school???"

Only a very small number of academic masters took a pen and paper and started to calculate.

And in the audience of the live broadcast.

buzzing...

A few seconds after the title came out, there was a burst of whispering in the auditorium, but because there was a competition on the stage, everyone paid attention to lowering their voices.

"Are all the questions in the third year of high school so difficult? I am dumbfounded." A sophomore student said.

"No way, we are also in the second semester of the second year of high school. I heard that there is not much new knowledge in the third year of high school?"

"I can't get enough of this option. If the questions in the third year of high school are so difficult, I will have no hope of going to college."

......

"How to do this... The scumbag expressed his face in a daze."

At the front of the auditorium at the scene, Liu Mingyuan and Lei Li brought teachers corresponding to several subjects, just to let them look at this topic when they were at the scene.At the same time, it is also to avoid wrong answers given on the spot, although this situation basically does not exist.

Lei Li and the others quickly asked the math teacher who came with the team: "How difficult is this problem?"

A middle-aged woman behind Lei Sheng said softly: "The difficulty is very high. It has exceeded the difficulty of the college entrance examination, but it is still within the range of knowledge points in high school mathematics."

"With Lei Sheng's level, can you answer it?" Lei Li asked.

"It should be possible, but I don't know how long it will take. Anyway, 5 minutes should not be enough." The math teacher estimated in his heart.

Hearing this, Lei Li frowned and didn't say much.

The auditorium of No. [-] Middle School not far from him.

"Ms. Liu, based on what you know about Ning Ning, can this child answer within the specified time?" Wang Wentao of the Local Support Center looked back at a middle-aged man.

"This question should be a high school math Olympiad question. Although Zhang Ningning has done many questions before, but there are not many of this difficulty. I can only say that she can definitely do it, but can she do it in such a short time of 5 minutes? It’s not easy to say, but it should be fine if the condition is good.” Teacher Liu said in detail.

"I hope they don't forget what I told them before, put away their arrogance, and winning the competition is the most important thing." Wang Wentao sighed softly, "I hope that kid Lei Sheng doesn't make trouble." As he said, He glanced at Lei Li not far away from the corner of his eyes.

Similarly, Wu Shan and others are also asking the math teacher brought by their school whether their students can answer this question correctly on time.But looking at their faces after hearing the reply, it was obvious that the reply they got was not what they expected.

"Now I can only hope that they can unite and solve this problem together." This thought came to everyone in the Five Schools Alliance.At the same time, several people became more and more disgusted with Liu Mingyuan.

Although it was proposed by their five schools to carry out this competition, according to their expectation, the six schools participating in the competition will create the questions internally, and the five schools will be more targeted when they participate in the question formulation. Come up with some topics that your students are good at.However, because of Liu Mingyuan's strong opposition, in the end, only the teachers from the Education Bureau and Jincheng University could submit the questions.This made a few of them feel uncertain.

Similarly, after the topic came out, Liu Mingyuan also turned around and asked the math teacher he had brought.

"I don't know. Our school has never taken such a difficult question." The female teacher hesitated for a long time before saying.

Liu Mingyuan choked for breath, froze for a moment, turned his head and didn't speak.

......

At the live broadcast, at the moment the countdown started, Zhang Ningning and the others began to count with their pens.Each of the five contestants this time has their own best subjects, but as a top student, their scores in other subjects are naturally not bad.Among them, Zhang Ningning is the one who is the best at mathematics among the five.

However, judging from the expressions of the five people, the difficulty of this question is not small.The five of them frowned and stopped after writing two strokes.

Zhang Ningning looked at this question. This question is no longer a normal high school knowledge. It should be an Olympiad question, and it may even be a question in the national high school subject competition.

The national high school subject competition, the high school level test, the full score is 70 points, but every year, few people pass the test with [-] points.

This question is a bit difficult, how can it be done within 5 minutes, if you give more time, it should be no problem to try it yourself.

Ding--

An alert sounded...
