consume不一定是要食用,任何形式的消耗都可以说是consume,请你再好好体会一下.

另外,对于这道题,我原来选C,可是后来再看的时候,觉得题目要问的是削弱K反驳M的理论的理由.

而天气因素是M没有提到的,K只是加入了这个因素.因此,我觉得气候因素不是K用来反驳M的理由.

不过B选项对应原文NOT ALL,的确有点问题~~

6题C反对的是M将exclusion of climatic change as an explanation, 也就是说这是M论证过程中的错误,但是问题问的是对M'theory的反对,上面说的气候变化不是theory的范畴之内的.

而B项刚好和THEORY对应,文中讲完M的理论,紧接着就是however,然后就是B项的内容,是直接对应的

呵呵，支持选C

如果B改成humain hunt的所有animal都extinct了，可能会像一点正确答案，否则削弱的力度不够强

同意！支持C!

K的主要观点：1）没有证据证明动物灭绝的地方，P曾猎杀过他们，小动物和植物不是P的主要食物；

                        2）K反对P排除气候变化；

后面又说K把人类作为次要原因。说明部分同意K的观点。那么主要反对的是K排除气候变化的因素。因此，气候变化一直都发生，就说明应该排除气候变化的原因。从而削弱K的观点。

支持B。 我把流沙提到的这道题目就是OG的29题。

29. The number of people diagnosed as having a certain intestinal disease has dropped significantly in a rural county this year, as compared to last year. Health officials attribute this decrease entirely to improved sanitary conditions at water-treatment plants, which made for cleaner water this year and thus reduced the incidence of the disease.

Which of the following, if true, would most seriously weaken the health officials’ explanation for the lower
incidence of the disease?
A. Many new water-treatment plants have been built in the last five years in the rural county.
B. Bottled spring water has not been consumed in significantly different quantities by people diagnosed as having the intestinal disease, as compared to people who did not contract the disease.
C. Because of a new diagnostic technique, many people who until this year would have been diagnosed as having the intestinal disease are now correctly diagnosed as suffering from intestinal ulcers.
D. Because of medical advances this year, far fewer people who contract the intestinal disease will develop severe cases of the disease.
E. The water in the rural county was brought up to the sanitary standards of the water in neighboring counties
ten years ago.

ETS的解释

The health officials’ explanation assumes that the decrease in the number of people diagnosed with the disease accurately reflects a diminution in cases of the disease. By pointing out that this assumption is false, C undermines the officials’ explanation and thus is the best answer. Since A supports the view that sanitary conditions have been improving, it tends to support the officials’ explanation. B also tends to support the officials’ explanation, because it eliminates a factor that might have differentiated between those contracting and those not contracting the disease and thus rules out an alternative explanation. The reduction of the severity of the diagnosed cases does not bear on the officials’ explanation. So D is not correct. Since the standards in neighboring counties might themselves have been inadequate, E does not weaken the officials’ explanation.

对比一下两道题目，觉得真的是很接近。

Nor were extinctions confined to large

(15)       animals:  small animals, plants, and

insects disappeared, presumably not

           all through human consumption.
        

K认为，当时不仅仅是large animals灭亡了，还有small animals, plants, and insects ，K推测，总不可能这些都是因为human consumption。

B.New discoveries indicating that Paleoindians made use of the small animals, plants, and insects that became extinct 。 正像ETS解释29一样，pointing out that this assumption is false。

C.Additional evidence indicating that widespread climatic change occurred not only at the end of the Pleistocene era but also in previous and subsequent eras。 按照ETS解释29 A选项一样,此选项为加强。  

虽然我选的是C，我觉得B更好了。

首先要说 OG中的题和这里的题还是不一样的

OG中的A选项只是说了water-treatment plants 没有说sanitary conditions 所以根本没有削弱作用。

个人认为这道题目不能用来引证GWD的这题。

 

我觉得B。C都可以，但B更佳。

因为原文中提到presumely,…………B直接否定了这个presume达到了削弱作用。更符合ETS的出题思路。

请大家指教

...看得我TOTALLY晕掉了...

最后还是没明白为什么E不对.

tangyuehua

B项和C项似乎都有问题，我做题的时候选了B。看了讨论之后似乎不知道选那个好了，更多要猜测出题者思路和ETS的偏好了。

个人感觉，C更好一些。

coolkaren

我觉得C更象答案.

ted810

做这题的时候就很疑惑，我认为C是正确答案。Cweaken的逻辑也符合原文啊。原文后面反驳古人不是extinction的原因，就是说古人很早就出现了，要灭绝动物，早就灭了。而c是说，天气不是原因，因为天气一直在变化，要影响早就影响了。

反观B，起不到很强的weaken作用。

很久以前的帖子了，但是我认为这种比较是不对的。gmat考试的逻辑weaken，强调的是通过否定前提来否定结论。og29的逻辑推理是，生病的少了——水源改善是起到了作用；正确的否定应该是否定推理前提，（这才是这两个题共同的地方）即生病的少了（c反驳了，因为c说生病的其实没少），故C正确。

gwd6q6，推理过程是，天气变化在动物灭绝的时候发生了——动物灭绝是由于天气变化。正确的否定要否定原因，就是天气变化不只在那个时候变化了，一直在变化，要灭动物早灭了，而且这个反驳逻辑在原文也用了，所以c正确
