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.

1. 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.
   
2. 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.

B 是不对的。 B如果对，他的假设是“老人得前列腺癌的死亡率更高”这是原文没有提到的。

E 正确。 没利用设备的死亡率大大的高，直接解释了现象。

选E   好歹沾边  
B里   Most men    你知道是哪的人不？万一是日本人呢？咋办？所以B错 根本就没关系

可是B只奖了R的不同，并没有讲R和T的不同啊？？

可是B只讲了R的不同，并没有讲R和T的不同啊？。。。。题目不是让解释Ｒ和Ｔ之间出现这种现象的原因吗？？。。。。

沾边的不一定对   但是不沾边的一定错   LZ说对不？
E里虽然只讲了R的情况   但是好歹提供了一种可能的解释   但是B里 根本就不知道那个Most men 说的是谁  万一是其他地方的  不就出错概率更大了么？呵呵~~B的范围有问题啊~~不知道说清楚没有~~
