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.

 

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?

这个题目挺阴险的

 

我把题目的意思翻译一下,

在Rubaria有非常完备的全民保健医疗系统,但是在Terland,仅有很少一部分人群可以享受到高质量的医疗保健服务。但是,尽管对大部分疾病而言,Terland的疾病死亡率都比Rubaria的疾病死亡率高,男性人口中死于前列腺癌的百分比 在Rubaria却远远高于Terland。

问解释:

 

选项我就不翻译了。之所以说这个题目很阴险,是因为题目尝试混淆两个概念: 疾病死亡率 (death rate for disease) 和 人口中死于某疾病的百分比 (the percentage of the population that dies from disease),前者是指在所有患该病的人口中的死亡比率,而后者是指对于整个人口中死于该病的人口比率。

换句话说 “Terland的疾病死亡率都比Rubaria的疾病死亡率高,男性人口中死于前列腺癌的百分比 在Rubaria却远远高于Terland“ 这个描述本身可能是不存在矛盾的,

为什么呢? 因为:人口中死于某疾病的百分比 = 人口中患该病的百分比 * 疾病死亡率

如果Rubaria和Terland的 关于前列腺癌的 人口中患该病的百分比 差别很大的话,足以解释题目中所谓的矛盾,

而B正好描述了这一事实:“大多数男人的前列腺癌患病年龄都高于Terland人民的平均寿命”,这句话就说明对总人口而言Terland的前列腺癌患病率低于Rubaria的患病率,所以即便患病死亡率T比R高,总人口死亡率T比R低也是完全可能的

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)
