As night falls, the desert reverberates with the wild roar of engines and the thunderous sonic boom of the desert, and the otherwise silent Sahara comes alive with rocket car enthusiasts from all over the world going on their racing extravaganza...

In Bern, Switzerland, on a sunny spring morning, in a classroom at an internationally renowned school on the banks of the Aare River, the atmosphere was quiet, and the students were all concentrating on their studies through the bright silver "Euclid Eyepieces" (a wearable hardware tool with a built-in audio-visual teaching system) worn on their heads, while Ms. Claire, who had blonde hair, was standing on the podium wearing Euclid eyepieces. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoThis is a Year 10 classroom with students in their prime, and Ms. Claire, who is 40 years old, is a history and humanities teacher at the school. On the podium, through the eyepieces, Claire was smiling as she was reading and correcting the homework that the students had handed in, but suddenly, somehow, she saw Ms. Claire frowning.

"Now, please pause your self-study and take off your goggles. Taking off the eyepieces, Ms. Claire gave instructions through the podium control screen, "The homework you have handed in has been corrected by the teacher, and now, Zhao Xiaoyun, please stand up." When the students all took off the eyepieces, Ms. Claire began to say with a serious expression, Claire's words came out, and when she landed, she saw a handsome young man standing up at that time, "Students, in the homework I assigned yesterday, there is an old proposition, the proposition hypothesis, saying that if one day, two people who are closest to each other in your life fall into the water at the same time, in the face of this situation, who will you save first?" Now, Zhao Xiaoyun, I would like to ask you to share your views on this issue with you. ”

"It's... I'm sorry, Ms. Claire, you know, I don't know how to swim..."Looking at Ms. Claire with an embarrassed look, Zhao Xiaoyun said truthfully, Zhao Xiaoyun's words came out, but at that time, there was a burst of laughter, "Don't laugh, everyone," Hearing this, her heart was really not bad, but Ms. Claire couldn't help waving her hand at that time, signaling the audience to be quiet, and said with a straight face:" In fact, what Zhao Xiaoyun said can be regarded as an answer to the question, just because, for a long time, there has been no standard answer to this question, and the reason why the teacher assigns this homework is actually just to exercise everyone's ability to think deeply about the problem. ”

"Okay, after sharing Zhao Xiaoyun's personal opinion on the question, next, I think, let's listen to other different voices," as she spoke, Ms. Claire's gaze fell on one person, intentionally or unintentionally: "Rong Shiyi," following Ms. Claire's call, and immediately, I saw a picturesque and slim girl rise up, "Now, I would like to ask you to share with you your answer to the proposition." "G... Ms. Claire, I... I personally believe that in the case of propositional assumptions, I... Will I choose to save the person who is closest to me?" I don't know if I was nervous, but I looked at Ms. Claire, and saw that the girl named Rong Shiyi looked a little nervous.
