1. 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.


这个题的思路是怎样的呢?题目的意思我不太理解

就是说流星在地球大气层的爆炸一个世纪一次。系统(我理解为防御系统)对未知的情况的反应是不可预知的。
问得出什么结论
ABCD都说清楚了system能干什么
只有E符合原文说的 The response....is unpredictable
