此题考查的是非谓语动词。
本句的主干是“Black boxes are important for people to find out the cause of an air crash”,因此,可以排除掉A和D选项——同一个句子里,不能同时有两个谓语动词。
而______ to record Flight data together with pilots' conversation and noises from the aircraft,是来修饰black boxes,与black boxes形成被动关系,因此排除掉B选项。因此,答案为C。
类似的句子还有:
The telephone, invented by Bell, is playing a more and more important role in our daily life.
