What was the possible reason for the shuttle disaster? [br]
NASA’s brightest investigators have toiled for six months to find out what caused the shuttle disaster. The leading theory was that a block of foam fell from the external tank, damaging a wing so severely that Columbia could not survive reentry. Today, in the most dramatic test so far, NASA simulated the forces at play. The foam, fired at 500 miles an hour into me reinforced carbon tunnel of a shuttle wing. The results left investigators astonished but also relieved. They now believe they’ve proved their theory of what caused Columbia to disintegrate high above Texas on the morning of February 1st with the loss of all seven astronauts aboard.
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。
