大家帮我看看OG-10啊

10. 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 nuclear blast, occur about once a century.

The response of highly automated systems controlled by complex computer programs to unexpected circumstances is unpredictable.

Which of the following conclusions can most properly be drawn, if the statements above are true, about a highly automated nuclear-missile defense system controlled by a complex computer program?

(A) Within a century after its construction, the system would react inappropriately and might accidentally start a nuclear war.

(B) The system would be destroyed if an explosion of a large meteorite occurred in the Earth’s atmosphere.

(C) It would be impossible for the system to distinguish the explosion of a large meteorite from the explosion of a nuclear weapon.

(D) Whether the system would respond inappropriately to the explosion of a large meteorite would depend on the location of the blast.

(E) It is not certain what the system’s response to the explosion of a large meteorite would be, if its designers did not plan for such a contingency.

笨笨啊,绕了半天我没绕清楚,答案是e,为什么c不对?是不是文中的unpredictable的意思是讲highly automated systems are unable to predict a unexpected circumstances(即该系统不能预测unexpected circumstances)因此选c则否定了题目的本意。是不是这样啊,我看og的解释没太看懂,大家帮我解释看看啊,谢谢大家!
