[求助]一道來路不明题请教

nanalin

In Rubaria, excellent health care is available to virtually the entire population, whereas very few people in Terland receive adequate medical care.  Yet, although the death rate for most diseases is higher in Terland than in Rubaria, the percentage of the male population that dies from prostate cancer is significantly higher in Rubaria than in Terland.

Which of the following, if true, most helps to explain the disparity between the prostate cancer death rate in Rubaria and Terland?

A. Effective treatment of prostate cancer in its early stages generally requires medical techniques available in Rubaria but not in Terland.
B. Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.

C. Being in poor general health does not increase one’s risk of developing prostate cancer.

D. It is possible to decrease one’s risk of getting prostate cancer by eating certain kinds of foods, and such foods are more readily available in Rubaria than in Terland.

E.   Among men in Rubaria, the death rate from prostate cancer is significantly higher for those who do not take full advantage of Rubaria’s health care system than for those who do.

我选E,答案B

请指教

Thanks!

这道题先读题干：explain the disparity between the prostate cancer death rate in Rubaria and Terland

读完题干知道是要解释矛盾的。原文的矛盾在什么地方呢。

health care in R is available to virtually the entire population, few people in T ,而the percentage of the male population that dies from P cancer is significantly higher in R than in T. 这里就有了矛盾。

而B说Most men who have P cancer are older than the average life expectancy for male inhabitants of T.

说明很多在T得了P cancer的人记做自然死亡了，而不是由于P cancer死亡，也就解释了原文得矛盾。

E肯定了hearth care 可以降低P cancer得病死亡率。不能解释原文得矛盾。

谢谢你"再次"的帮我解答问题

即使R的health care>T,
但是T得P cancer的人,是自然死亡的
跟health care比较差,无关

是这样吗? 我觉得我好笨喔

leeon

多多分析，自然也就提高。原文的矛盾是R的health care>T，而R的死于P cancer的人>T的，B说是由于T的死于P cancer的人记做其它死因了，所以这个数字不准确，从而也解决了原文的矛盾。多读读逻辑区精华贴子，尤其是mindfree的，能启发我们的思维。

对不起,是我的错,没有标明出处
但这道题我皆不是得自GWD,OG,费费,大全,LSAC,新东方....
是友人询问

也许以上这些出处也可以找到这一题,但我不是从以上看来的

一定要注明题的出处嘛?

注明出处是为了别人也能搜索到，就像有些题你不清楚但别人已问过并讨论过，你可以搜索到别人的讨论，这是利己利人的事，另一方面也可减少工作量。当然，如果不知题的出处，就没办法，说明一下

以下是引用pumpkin在2004-8-20 6:02:00的发言：

只要是GMAT的题目， 或者LSAT题目， 除了GIGI最新题目， 都能找到

谢谢你

ctrl+f 我知道啊

我不是不会找,而是这题真的"无法"说出来源

都不是从GG13,OG,費費,大全,LSAC,新東方.... 来的
