Archaeologist: Researchers excavating a burial site in Cyprus found a feline
skeleton lying near a human skeleton. Both skeletons were in the same sediment
at the same depth and equally well-preserved, suggesting that the feline and
human were buried together about 9,500 years ago. This shows that felines were
domesticated around the time farming began, when they would have been useful
in protecting stores of grain from mice.

Which of the following, if true, would most seriously weaken the archaeologist’s
argument?

(A) Archaeologists have not found any remains of stores of grain in the
immediate vicinity of the burial site.
(B) The burial site in Cyprus is substantially older than any other known
burial site in which a feline skeleton and a human skeleton appear to have
been buried together.
(C) Paintings found near the burial site seem to show people keeping felines
as domestic companions, but do not show felines hunting mice.
(D) In Cyprus, there are many burial sites dating from around 9,500 years
ago in which the remains of wild animals appear to have been buried
alongside human remains.
(E) Before felines were domesticated, early farmers had no effective way to
protect stores of grain from mice.

此题选D
错选了A，还是不太明白，原文说了猫被驯养用来保护grain，那没有发现stores of grain不也能说明不是framing开始的时候吗？
另外能不能顺带解释下C，
谢谢各位！！！

CR题最主要的一点就是：不带代入自己额外的假设！

你是不是额外的假设了store of grain是farming开始的必要条件？就不能farming开始的时候，grain不放在store了，放在裤裆里带着？明显store of grain和farming开始之间有一个gap。故A错。
C选项同样需要额外的假设才能成立：你必须自己假设paintings near the burial site必须反应的是当时的真实情况。就不可能这些Paintings都是一个熊孩子瞎画的？或者古时候有一个精神病人有臆想症，瞎画？
D正确是因为D质疑了结论成立所必需的assumption:这些felines是作为domesticated animal和human是同时入葬的吗？万一人们是随便抓了几只wild animal跟人葬在一起呢？assumption是假设成立的必要条件，assumption为假，则结论必为假。

谢谢~A还是有点纠结。。。原文结论说This shows that felines were domesticated around the time farming began, when they would have been useful in protecting stores of grain from mice. when引导的从句不是进行说明farming开始的时候猫 useful in protecting stores of grain？我主要是看着这个从句才一直纠结的。

赵本山直接叫范伟买拐范伟会买吗？不得忽悠？
GMAC为了增加选项的难度会怎么办呢？

哈哈，想明白了，谢谢啦

我一开始也选了A，但仔细读题目后，发现A确实不如D：
1. 选A一定因为作者最后一句话，但作者用的是would have been useful....这是表猜测，而不是fact
2. D选项直接削弱了假设。一开始直接淘汰掉了D因为觉得跟题目说的不是一类事物，但仔细看发现feline本身就是在说wild animal被驯化。

咱俩的疑问一样。但其实读题的时候要搞清楚什么才是作者真正的conclusion.这道题的主逻辑链是 “猫跟人9500年前埋在一起“推出”猫在农业开始的时候被家养了（conclusion）“   “when they would have been.."是作者提出的关于猫具体被家养干什么活的hypothesis,一种可能的情况他说在农业开始的时候猫可能已经能保护粮食了。
然后理清逻辑链了以后，开始做题。A最多能削弱作者关于猫被驯养干啥活的假说，不能削弱到结论。就算猫没有保护粮食，也可能被家养，就是单纯的当当宠物而已。排除
C还是在削弱假说，而跟结论一致。排除
D说同一时间有很多野生动物跟人埋在一起，不是只有家养的才能跟人埋在一起啊。加强了猫也是野生动物的可能性，削弱了结论。正确
这道题的陷阱还是很坑的，通过添加修饰成分，让你分不清什么才是真正的结论。我们要做的就是抓住主干信息，体会句意，来避免掉进去。
