　　GMAT逻辑机经:动物语言

　　某教授说，人们现在对于animal language的研究已经很牛逼啦。我们已经知道53种语言啦。No animal language is discrete infinity language. Therefore, no animal language is natural language.

　　以下哪个选项必须作为assumption支持以上结论?

　　Lz选 Every natural language is discrete infinity langrage. (这题好奇葩，于是完整记下来了。。

　　考古

　　科学家在过去的50年中研究了很多的语言。人类的语言都是XXXXX的;而动物的语言[communication system]都不是discrete的，于是得出结论：动物的语言[communication system]都不是native language。问Assumption。

　　我选的：Native language都是discrete的。

　　大意是说animals’ language system。作者认为，“we know that animal systems are not discrete”能够推出"as a result, animal systems are not natural"。也是考充要条件的。

　　GMAT逻辑机经:老房子和新房子

　　一个镇子上的老房子的质量都比新建的房子的质量好，维修次数少，依然坚挺神马的。于是镇上的老人家认为，现在的房子粗制滥造偷工减料。

　　以下哪个选项weaken了老人的结论?

　　Lz选当年质量不好的老房子现在都塌了所以你没看到

　　考古

　　有人说现在房子的质量不好了，原来的房子好。问一个解释/加强

　　参考：质量不好的老房子随年代已经坍塌

　　某年代的`老房子普遍比现在的房子质量好，因此推断出那时候的建筑工更厉害。问：削弱

　　说一个人发现建的早的房子比新造的房子坚固，所以以前的人的造房子工艺比较好。削弱题。狗主选项：选D，建造的早但是不坚固的都已经倒了

　　原文逻辑链：(确认和OG12上面114题十分相似)老房子质量好推出当时的建筑工更厉害

　　变体：选项是反着说的就是质量不好的都倒拉拆掉了之类的

　　OG中类似题

　　OG12-CR-114.

　　Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

　　Which of the following, if true, most seriously weakens the guidebook writer’s argument?

　　(A) The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.

　　(B) Hotels built since 1930 can generally accommodate more guests than those built before 1930.

　　(C) The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.

　　(D) The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.

　　(E) The average length of apprenticeship for carpenters has declined significantly since 1930.

　　The correct answer is D.
