*标题说明: 1. "OG10-10",为了以后与OG11题目区别,例如: OG11的第一题,题目就写"OG11-1逻辑讨论贴汇总" . 2. 括号中的内容有两个目的, 一是方便搜索, 因为论坛里前几年的贴子都是用这个号索引的; 二是可知OG11对应的是哪题, 或有无此题. *搜索的格式有3种:“OG10”(没有空格没有横杠),“OG-10”(中文模式下的长杠和英文模式下的短杠是一样的,没有区别),和“OG 10”(OG加空格加题号)。 *做这个贴子是由携隐发起, 想参加的看进来: 诚征攻克GMAT资料方法收集汇总志愿者(已发email给群成员) 作者:携隐 浏览:942 回复:33 → 【走出GMAT困境】 2008-1-18 1:47:08 [精华] *每贴一题, 每贴都包括三个内容, 原题及OG解释,讨论贴汇总的链接,摘录的经典讨论. *大家如有更加简洁易懂的解释, 欢迎跟贴,最终汇总成册。 开始啦... --------------------------------------------------------- 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. OG解释: If the defense system designers did not plan for the contingency of large meteorite explosions, such explosions would, from the system’s perspective, be unexpected. The system’s response to such explosions is consequently unpredictable. E expresses this inference and is thus the best answer. A cannot be inferred since it is consistent with the stated information that no meteorite explosion will occur within a century. B cannot be inferred since there is no information to suggest that meteorite explosions in the atmosphere would destroy the system. C cannot be inferred since it is consistent with the stated information that an appropriately designed nuclear defense system might be able to distinguish nuclear from meteorite explosions. D cannot be inferred since there is no information to suggest that the location of blasts would determine the appropriateness of defense system’s response.
