求助GRE逻辑题exercise3的第十题
9.The closest distance from which an asteroid has been photographed using ground-based radar is 2.2 million miles,the distance from which the asteroid Toutatis was recently photographed.The closest photograph of an asteroid is of Gaspra,which was photographed from a distance of only 10,000 miles.
Which of the following can be properly concluded from the statements above?
(A) Toutatis is more likely to collide with the Earth than Gaspra is.
(B) Toutatis,unlike Gaspra,has only recently been discovered.
(C) Asteroids can be photographed only by using ground-based radar.
(D) Ground-based radar photography cannot take photographs of objects much beyond 2.2 million miles from Earth.
(E) The photograph of Gaspra was not taken using ground-based radar.
答案选的E,可是我觉得这一段文字里并没有证据证明这张照片不是用地面雷达拍摄的啊,E推不出来吧
【这个答案是别人给的我怀疑会不会有错】

你看距离啊,一个是2.2 million miles,一个是10,000 miles.
就是说常识是ground-based radar大概2200000米,但这个才10000米
