How thd NASA’s investigators prove the reason of thsaster?
选项
A、By studying the video tape.
B、By analyzing the data concerned.
C、By anatomizing seven astronauts’ body.
D、By making a simulated experiment.
答案
D
解析
细节判断题。新闻前面提到的导致“哥伦比亚”号失事的原因只是一个猜测,要想证明这一点还需要一些实证,于是“美国国家航空航天局模拟了泡沫材料碎片对机翼的冲击”,试验的结果“他们确信实验证实了他们的推论”,由此可以看出,确定的方法是通过模拟的实验,所以选项D的表述是正确的。
