What is the main topic of this news? [br]
Scientists say that nighttime flights are much more damaging to the environment than daytime air travel. In new research published in journal Nature, they say vapor trails produced by aircrafts do far more damage during the night. The reason is condensation water vapor emitted from hot engine of aircraft condensing into trailing clouds. Our science reporter M. G. has more. "The scientists say that in daylight the trails act like mini-clouds. They are good for the environment because the white color deflects the Sun’s rays and reduce temperature. At night from the sun goes down this positive benefit is lost. The impact of night travel is surprisingly large. In the United Kingdom only a quarter of flight takes place in darkness. But this accounts for up to 80% of greenhouse effect from condensation."
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。
