But not all sides are in agreement on this. Different researchers have given different results. In addition, the height of the mountain can change over time. That’s why a Chinese survey team with over 30 members set out to reach the peak of Qomolangma to re-measure its height on May 6, 2020. They were equipped(配备) with the latest technology. It is not an easy task. The average air temperature on the mountain is -29℃, and powerful winds blow all the time. In such bad conditions, surveying drones(无人机) cannot work at the peak of the mountain. That’s why it’s still necessary to send human experts to the peak to get exact results. But does a difference of a few meters really matter when it comes to a high mountain In fact, measuring the height of Qomolangma is about more than just getting one exact number. Mount Qomolangma is at the point where the Eurasian plate(欧亚板块) meets the Indian plate. It formed 38 million years ago as the two plates hit each other. Changes in the peak’s height can show whether the two plates are heading toward or away from each other. This can help us understand the movement of the earth’s crust(地壳). The survey team will also get first-hand information about environmental conditions at the top of the mountain. This will help us understand how climate change has affected the Qinghai-Tibet Plateau(高原). (　)21.What do we know from the first paragraph A. Researchers measure the height of Qomolangma every year.
