问题 When did the space shuttle Endeavour land Wednesday night?
  
The space shuttle Endeavour and its crew of seven returned to Earth Wednesday, making a rare nighttime touchdown to wrap up "a two-week adventure" at the international space station. The shuttle landed in darkness Wednesday night after its scheduled landing was delayed by cloud cover. The shuttle swooped through the darkness and landed on NASA’s illuminated runway at 8:39 p.m., an hour after sunset. The shuttle’s homecoming was a bit delayed. Endeavour was supposed to land before sunset, but at virtually the last minute, clouds moved in. As the astronauts took an extra swing around the planet, the sky cleared enough to satisfy flight controllers and—after asking Gorie for his opinion—they gave him the green light to head home. It was only the 22nd space shuttle landing in darkness. Fewer than one-fifth of all missions have ended at nighttime; the last one was in 2006.

选项 A、The space shuttle would be under close inspection.
B、One of the crew members failed to head home.
C、Unexpected weather delayed the landing of Endeavor.
D、The space shuttle made a smooth landing.

答案C

解析 新闻中提到,奋进号航天飞机原本定于日落前降落,但在最后关头突然云层聚拢,宇航员只好推迟降落,等到天空明朗符合飞行条件时才降落。可见新闻主要叙述无法预测的天气因素如何导致奋进号航天飞机推迟降落,因此C为正确答案。
