问题 The main idea of the passage is about ______.
What can be inferred from this passage?

选项 A、Nowadays science is learning more and more about the impact humidity has on all of us by using sophisticated measuring devices.
B、Humidity could interfere with television signals.
C、Humidity may warp priceless antiques.
D、Visual disturbances may decrease in days of low humidity.

答案D

解析 本题为推理题。问根据短文可以推理哪项结论。注意其他三项文中均直接提及到,无须推理。文中第三段说,湿气干扰了电视图像质量;但当一股干燥气流降临时,人们的抱怨也就少了。因此可以推理,在湿度较低的日子里,图像受干扰的情况会减少,答案选项符合该信息,故为正确选项。
