As the leader of this year's IBO question group, Percy is supportive of the increased difficulty and volume of questions in this IBO.

But unlike those extreme Westerners, he is always vigilant and fearful of the rise of the Xia Kingdom. It seems that even if a genius high school student is born in the academic circles of the Xia Kingdom, he will feel the humiliation of being slapped in the face and the fear of being surpassed.

Sense of crisis.

He is not like those prestigious universities that always want to recruit all the world's talents into their school, assimilate them as one of their own, and contribute to the school's "alumni circle", and they try to persuade this talented high school student from Xia State in every possible way.

Offer a tempting olive branch.

He did it more out of his dignity as a question expert and the pleasure of finding "a close friend."

As a biology educator who has studied Biology Olympiad questions for most of his life, the Olympiad questions are like exquisite works of art in his eyes. He likes to watch the candidates meditate on the exam papers that he has carefully prepared, and then bang their heads and bleed.

, broken and sinking into the sand, his face full of sorrow.

This will give him a sense of accomplishment.

Of course, if a candidate can use his wonderful thinking to solve the deepest trap hidden in the question, then he will also be happy, because it will give him the joy of scratching an itch.

As he grew older and more senior, he naturally became the leader of the IBO question-setting team. He rarely set questions in person, but he would still ponder some "world-class" problems in his spare time.

For fun.

The two big questions in the additional volume this time were the ones he had pondered over the past few years, and they were extremely difficult.

Although it is all knowledge within the scope of high school, the knowledge points are very rare, and the knowledge points in different subdivisions are closely linked. If any small knowledge point is not fully understood or not in depth enough, it will cause misunderstandings and lead to inconveniences.

Wrong fork in the road.

For example, the first additional question involves several sub-disciplines such as the behavioral system of ethology, genetic variation and multiple allelism, and cell structure and function of cell biology. The question even includes mannitol and quality.

The relationship between wall separation, the correlation between the extinction amount of vegetation and the altruistic behavior of animals, the correlation between the diffusion direction of gas molecules and the gas partial pressure in animal cells, arterial blood, and tissues, the genetic variation of tunicates, etc.

What's more difficult is that the first seven questions are indefinite choices, with as many as six options ABCDEF. As long as one option is missed or multiple choices are made, it will be judged as all wrong and no points will be obtained.

The next few questions require drawing cell structures, answering the regularity of genetic variation, and solving practical problems through the characteristics of animal altruism.

This requires candidates to have a very broad vision, very deep and even complex biological knowledge points, and also to be able to think flexibly, draw inferences from one example, and achieve a comprehensive understanding of all sub-disciplines within the entire subject.

——This is something that even the experts in the review team could not do. They spent more than four hours working together to solve the first question even though they could look through the reference materials, and the eighth question of drawing cell structure

Xiao Wen didn’t draw it completely right either.

It can be seen how difficult these two additional questions are.

For the candidates from Xia State, the difficulty of this abnormality has increased a bit, because the additional papers are all in English, and they must translate them into Chinese before they can answer the questions.

Because it involves too many knowledge points and too many professional nouns, some nouns even have no corresponding Chinese vocabulary at all. For forced translation, we can only use transliteration or free translation, making up nouns that are not found in Chinese textbooks - Representative Xia Guo

Coach Xu, who was responsible for translating the team, and the accompanying full-time translator both expressed their inability to do anything and had no choice but to give up on translating the additional volume.

——Probably in their opinion, even geniuses like Qin Ke and Ning Qingyun are unlikely to be able to do the additional papers that even them have a headache. In addition, the English level of these two students is quite high.

Random translation will affect their judgment of the topic, so it is better to maintain the original English version.

The situation is similar in other countries, so the additional paper is unique and all candidates use the English version of the paper.

Of course, the vast majority of candidates had already heard the news and did not waste time touching the additional paper. They just concentrated on attacking the main theory paper with all their strength.

With only 5 hours, they didn't even have the confidence to finish the more than 150 questions in the main paper. How could they have the time and energy to do the additional paper that was said to be hellishly difficult?

Percy walked slowly in the examination room. Looking around, most of the candidates were frowning and working hard on the main theory paper. Judging by their speed, which candidate could complete the test within five hours?

If you complete two-thirds of the questions, you can definitely win the gold medal.

Percy's eyes fell on the magical "Miracle Boy" of Xia Kingdom again.

What's different from others is that this kid's expression is as calm as water, and he never stops writing the pen in his hand. He just writes the answers after reading the questions. He hardly needs to spend time thinking, and he doesn't touch the scratch paper. He just cuts the melons and vegetables.

He kept killing it all the way, solving the questions so fast that Percy was secretly stunned.

He is worthy of being a monster who got full marks in all three international science Olympiads, and his thinking speed is simply astonishing.

Not only was Percy paying attention to Qin Ke, but the other invigilators in the examination room also glanced at Qin Ke from time to time.

Although in the eyes of Westerners, the appearance of yellow-skinned Xia people is difficult to identify, this Xia student is different. He is wearing the uniform of the Xia national team, and has naturally curly hair that looks a bit messy. The top of his head is

His dull hair is his trademark. Anyone who has watched the previous International Olympiad Awards Ceremony in Mathematics, Chemistry, and Physics can easily recognize him.

Therefore, the invigilator who "accidentally" passed by Qin Ke couldn't hide his shock, because this high school student from Xia State answered the questions too fast.

Half of the questions in this IBO are open-ended multiple-choice questions. This guy is good. He glanced at the questions and chose the answers directly. Even those who have memorized the answers may not be able to answer as fast as him. After all, it takes time to recall the answers.

of!

This chapter is not over yet, please click on the next page to continue reading! Fortunately, the subsequent questions and answers, calculations, and essay questions slowed down his speed. Otherwise, all the invigilators would have been worried about whether he could hand in the paper in half an hour.

No wonder the organizing committee of this IBO acted as if they were facing a formidable enemy when they found out that Qin Ke was about to take the exam, and even issued an additional paper that was extremely difficult!

Under the "watching" of Percy and several invigilators, Qin Ke stopped writing, collected the thick stack of papers, and put them in the corner. The answers were already written on them, and they were all

Answer in English!

Percy looked up at the wall clock in the examination room, 56 minutes! In 56 minutes, the boy from Xia Guo had completed 150 questions!

If he hadn't seen it with his own eyes, Percy wouldn't have believed it. Even an old biology educator like him with decades of experience couldn't do it at such a speed!

It’s amazing, it’s really scary. This is the first time in my life that I have met such a talented student!

Percy was inexplicably excited at this time, because he saw Qin Ke picking up the additional volume! His proud work!

This is a top-level problem that he spent several years of hard work to figure out. Originally it was just for his own entertainment and pursuit of the ultimate art of competition difficulty. He never thought of using it as a public examination paper. This time it can be said that it is for this Xia Kingdom.

student, he decided not to indulge in self-admiration anymore and took it out as an additional question in the finale!

Qin Ke didn't notice Percy, all his energy was focused on the question.

He carefully read from the first big question to the twelfth small question at the end. After reading it, he slowly closed his eyes. He needed to search for relevant knowledge points from the boundless knowledge in his mind.

These knowledge points are so rare that they will not even appear in textbooks. They will only appear in very unpopular high school extracurricular readings. However, no matter how rare they are, as long as they have appeared in this world before, they will only appear in high school.

The knowledge points will be incorporated into the "International IBO" level biological subject knowledge and imprinted in Qin Ke's mind.

What Qin Ke needs to do is to use his extraordinary scientific thinking to connect all these uncommon knowledge points and flexibly apply them to solve problems.

Percy saw that Qin Ke had finally fallen into thinking this time, and did not pick up the pen and start writing like the previous main volume. Apparently, the first interlocking and unfamiliar knowledge points at the beginning gave him a headache and he needed to spend time to recall them.

.

The corners of Percy's lips curled up. He stopped patrolling around and stood behind Qin Ke, watching him do the questions.

Dozens of experts in the previous review group, when they saw the first question, they exclaimed, "Oh my god, what kind of devilish question is this!" "This is too difficult!" "It took me just to understand the question.

Fifteen minutes!"...Of course, these exclamations also filled Percy with a sense of pride and accomplishment.

He was very curious about how long it would take this Xia Guo student, known as the "Miracle Boy", to solve this first question, or in other words, whether he could solve this first difficult problem.

Time passed bit by bit. Seeing that more than a minute had passed, Qin Ke still closed his eyes, but the pen in his hand suddenly began to spin back and forth quickly between his fingers, spinning faster and faster, almost at any time.

It may fly out, but it never misses.

The curvature of the corners of Percy's mouth became wider and wider.

Your pen-turning movements are of course so precise that they are breathtaking, but how will they help you solve the problem?

But the smile on Percy's lips froze in the next moment, because the pen turning on Qin Ke's fingertips suddenly stopped. His eyes also opened at this moment, and when he turned his fingers, the pen was already clamped between his fingers.

At this moment, Qin Ke was like a top swordsman who had drawn his sword. His momentum suddenly changed, and his pen suddenly landed on the answer area of ​​the additional volume, and then started to move like a dragon and snake.

A,ACF,EF,BCD,AF,B,ACDE!

Qin Ke actually solved the first seven indefinite multiple-choice questions in one go, and the answers were all correct!

This...how is this possible!

Percy stared at this scene dumbfounded, but saw that Qin Ke had begun to draw a cell structure in the answer area of ​​the eighth question with fluent strokes. He drew it very carefully, and all the test points involved were integrated into this cell structure.

In the picture.

Because it was too detailed, this cell structure diagram took him almost ten minutes. Although the painter was very ordinary, the details were impeccably clear. Even if Percy answered it himself, he would not be able to draw it to such a level of detail.

Qin Ke ignored Percy's amazed look behind him. The questions in this additional paper were indeed very difficult. The test was too unpopular and detailed. Even if he mastered these extremely rare knowledge points, if he could not use them flexibly, he would not be able to answer them at all.

Not coming out.

Most of the perverts who ask this question specialize in these rare subdivisions of biology, or have spent countless hours studying them.

Qin Ke hadn't been interested in subjects other than mathematics for a long time, but this extremely difficult biology question made his blood boil.

He shook his numb and sore wrist and continued to write in English to explain the movement in the cell structure.

"phospholipids to move between both leaflets of the bilayer in transverse movement, in a flip-flop manner... (phospholipids move sideways between the upper and lower layers of the bilayer structure...)"

A eloquent six or seven lines of English explanation is not difficult for Qin Ke, who has now pushed his English skills to the limit. The difficulty is just how to accurately explain the thoughts in his mind.

After finishing the eighth question, he went straight to the ninth question without stopping.

“ATP is better than either glucose or fatty acids as an energy source for cell metabolism…(ATP is better than either glucose or fatty acids as an energy source for cell metabolism…)”

Percy kept his mouth slightly open, looking at the scene in front of him with shock on his face, and the shock in his heart was beyond words.

He had no doubt that the answer was leaked, because Qin Ke's answer was more detailed than the standard answer he wrote!

Percy suddenly remembered that when he was young, he always got full marks in exams. Once, the teacher asked him a very difficult problem to test, and he finally solved it. He could never forget the teacher's unconcealed look of amazement at that time.
