标题: [求助]完全不明白这道题GWDTN24-Q3

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 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.

答案选B。我选了C

原文在说R的health care好,T的health care极差,又说R的死亡率比T低,但是矛盾的是在T男人因为PCancer死了的比率更高。

我能联系起来的就是health care与Pcancer无关,所以选了C

看不懂为什么B是正确答案,C为什么不对呢?!

B.    Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.

It means that males of T usually die earlier, so they won't have chances to get prostate cancer.

So B is the best answer.

        C.    Being in poor general health does not increase one’s risk of developing prostate cancer.
        It doesn't mention anything specifically about "men". This choice is too general to explain why.
