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.
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.
答案是B.
答案是B.
脑子转不过来，活的长跟得病率高有什么关系？哪个大N给讲讲？
脑子转不过来，活的长跟得病率高有什么关系？哪个大N给讲讲？
简单的说，B是说，T男子还没到患上Prostate的年纪，就死翘翘了。
1. 如果分析一下，我是这么考虑的：
解释题，先看矛盾点：R居民医疗条件比T居民好，大部分疾病死亡率比T居民低，但是死于P的男性，R却比T多。
A、
对早期P的有效治疗，R有，T没有。（原文不涉及早期治疗问题，也没有涉及这个比较。无关）
B、
患P的男性年纪比T男性的平均寿命更长。（单从有关无关上考虑，这个选项既涉及患P也涉及生死，是有关选项；从逻辑上考虑，也完全能解释那个矛盾点。）
C、
总体健康情况差并不会提高患P的风险。（但是也并没有说明健康差一定不会患P，所以解释不了矛盾点；事实上，原文也没提健康状况差，仅仅从“大部分疾病死亡率”是无法推出健康状况差的。实质上，这还是无关选项。）
D、可以通过食用…降低患P风险，这些东西R和T都有。（纯属无关）
E、
在R，那些没有充分利用其医疗条件的居民，P死亡率高于充分利用的居民。（原文没说，无关）
赞，谢谢MM.
被你的答案逗了好久。
A) can not explain the the reason;irrelevent
B) which indecates that the man with caner in terland can live longer than average life expectancy.
C) Irrelevent, cos the article doesnot dicuess the relationship between the general health and prostate cancer.
D) Irrelevent ; not discuess the food and out of rang
E) Still can not explain the reason why the death in ruberia higher than in terland

非常感谢！解释得很清楚！
看到一个 老美的解释挺好的
you need to pick a choice that actually points out a salient difference, regarding prostate cancer, between the two countries.
furthermore, that difference must register in the correct direction: i.e., the evidence must indicate that prostate cancer is LESS likely to be found in terland.
choice (c) does no such thing. in fact, choice (c) is perfectly neutral, giving absolutely no reason to suspect different levels of prostate cancer in the two countries. (first, "does not increase one's risk" implies equality of risk, not a disparity in either direction. second, this statement has absolutely no bearing whatsoever on differences between the two countries mentioned in the problem.)
choice (b), on the other hand, mentions a factor that is DIRECTLY responsible for the relatively low rate of prostate cancer in terland.
namely, if people in terland don't live long enough to GET prostate cancer in the first place, then you aren't going to see a lot of prostate cancer there. and there you have it.
--
by the way, this problem is an exact analogue of the real-world situation with such maladies as heart disease and breast/prostate cancer, which generally strike older individuals.
there are often strikingly low rates of death from those maladies in countries with otherwise horrible public health (such as sub-saharan african countries). this isn't due to better prostate/heart/breast health in those countries, though; it's simply because most people in those countries don't live anywhere near long enough to get these problems in the first place.

正确答案B错！B说：在T，大部分前列腺患者都比T县的正常人长寿而原文问的是为什么前列腺患者的死亡率R>T ...
