问题 Why is the night flight more harmful?

选项 A、Because it is not safer than daytime flight.
B、Because it leads to greenhouse effect.
C、Because it reduces temperature.
D、Because it is not good for human health.

答案B

解析细节判断题。新闻使用了对比的方式说明为什么飞机的水汽尾迹在白天是有利的，但在夜晚会对环境造成影响，导致温室效应。结尾的举例中出现了greenhouse effect一词，由此可以判断B项是正确答案。
