题目如下：
Meteorite explosions in the Earth's atmosphere as large as the one that destroyed forests in Siberia,with approximately the force of a twelve-megaton muclear blast,occur about once a century.
The response of highly automated systems controlled by complex computer programs to unexpected circumstances is umpredictable.
Which of the following conclusions can most properly be drawn,if the statements above are true,about a highly automated muclear-missile defense system controlled by a complex computer program?
A 略
B 略
C It would be impossible for the system to distinguish the explosion of a large meteorite from the explosion of a nuclear weapon.
D 略
E It is not certain what the system's response to the explosion of a large meteotie would be,if its designers did not plan for such a contingency.
C选项中Meteorite explosion 的能量与twelve-megaton nuclear blast 的一样，因此无法分清，为什么错呢？
我觉得C和E都是有道理的，OG上的解释说实话，我没有看明白。
请各位大虾指点，多谢！！ [em04][em04] |
