以下是引用allen0018在2006-7-19 12:02:00的发言:大全-3-5. A weapons-smuggling incident recently took place in country Y. We all know that Y is a closed society. So Y’s government must have known about the weapons. Which of the following is an assumption that would make the conclusion above logically correct? (A) If a government knows about a particular weapons-smuggling incident, it must have intended to use the weapons for its own purposes. (B) If a government claims that it knew nothing about a particular weapons-smuggling incident, it must have known everything about it. (C) If a government does not permit weapons to enter a country, it is a closed society. (D) If a country is a closed society, its government has a large contingent of armed guards patrolling its borders.(E) (E) If a country is a closed society, its government has knowledge about everything that occurs in the country.
这道题,大家能说说究竟怎么推离出来的吗?我逻辑概念有点模糊
不让在这里讨论单题,冒个险 premise: Y is a closed society Conclusion: Y’s government must have known about the weapons 前提和结论中间还缺点东西,是吧?预测的答案是In a closed society, Y's government must have known about the weapons. 但是ETS不会让题出得这么容易,然后把答案变化了一下。你看E是不是包含了我们刚才预测的答案,是个大集合。 典型的搭桥型。 |
