参考答案：对

解析：[听力原文] With major airports facing chronic traffic jams and nobody volunteering to have a new airport built in his backyard, how is the air-travel boom going to sustain itself One answer may come from the Department of Defense, which had sponsored development of an innovative new type of aircraft that doesn’t need a runway; its engine pods point upward for vertical takeoff, then tilt horizontally for forward flight.

[分析]： 词汇理解。 原文首句提问：航空业在面临种种困难的情况下如何保持繁荣兴盛 接着，文章给予回答One answer may come from the Department of Defense，which had sponsored development of an innovative new type of aircraft that doesn’t need a runway...即国防部已出资研制一种新型飞机，该飞机不需跑道……显然题干信息与原文相吻合，是正确的。[解题关键] 能够确定题干中prosperity，invest分别与原文中boom，sponsor是同义替换。
