OG. No.10 参考答案在page 562
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-missles defense system controlled by a complex computer program?
A) within a century after its construction, the system would react inappropriatedly 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 inappropriatedly 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.
Choices A and C cannot be inferred since it is consistent with the stated information that no meteorite explosion will occur within a century and that an appropriately designed nuclear defense system might be able to distinguish nuclear from meteorite explosions
自由的理解:A和C不能被正确推断出来,因为它一致于所说的信息:没有流星的爆炸发生在一个世纪时间内。因为一个正确设计的核防御系统可能能够区分核爆炸同流星的爆炸。
自由的问题:结合题目和答案,我没明白OG里上面想表达什么意思。而且从上面字面的含义,我觉得OG的解释方向好象也很牵强,自由自己的理解是,A和C属于原文没有提到的内容,C没提到原文的内容,而A是对原文含义的篡改。
谢谢大家的指教。
