Question 7 is based on the news report you have just heard.

      The world’s largest aircraft has taken to the skies for the first time. （5）The Airlander 10 spent nearly two hours in the air, having taken off from Cardington Airfield in Bedfordshire. During its flight, it reached 3,000 feet and performed a series of gentle turns all over a safe area. The aircraft is massive—as long as a football field and as tall as six double decker buses and capable of flying for up to five days. （6） It was first developed for the US government as a long-range spy aircraft but was abandoned following budget cutbacks. （7）The aircraft cost 25 million pounds and can carry heavier loads than huge jet planes while also producing less noise and emitting less pollution. The makers believe it’s the future of aircraft, and one day we’ll be using them to go places. But there’s still a long way to go. The Airlander will need to have 200 hours’ flying time before being allowed to fly by the aviation administration. If it passes though, we can hope we’ll all get some extra leg room. 

7. What is the advantage of the Airlander 10 over huge jet planes?

解析：D。根据文章可知，Airlander 10与大型喷气式飞机相比更能承重、产生的噪音更少、污染更少。D项是对后两种特点的改写。因此选择D项。
