TT GWD11-Q19

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.

4. 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.
5. 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.
                               

请大家帮忙分析一下，我不知道为什么要选B，想不明白。谢谢

还是不会

假设die from p cancer=头发掉光

那么因为T那个地方的人在得病的时候岁数都超过了平均年龄,所以他们die naturally 的几率就很高了

也就是没等头发掉光就死了.所以不能定义为die from p cancer

可以解释为什么Tdie from p cancer低于R

不过个人感觉这个解释太牵强,也是实在因为没别的可选吧...

意思是不是相反了？

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?

正确选项要涉及到T、R二者的比较才行

而B中

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

都是在说T，没有一点R的信息

设想，如果

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

也成立，R、T情况一致，那么B选项就无法解释原文差异了

再看看其他选项：

A，有比较，但推理方向相反，推出前列腺患者死亡率R<T，无法解释为什么现象死亡率R>T

C，C说：一般来说，医疗条件差不会增加前列腺患者疾病恶化的风险

但是不会恶化无法解释T死亡率相对低了，因为在R，也许医疗条件好可以提高治愈的成功率，不会恶化与死亡率无关

D 同A

E 在R前列腺患者大多都是那些没有好好利用良好医疗条件的人

看看原文推理：

医疗条件R>T -----> 前列腺死亡率R<T -------> 现象前列腺死亡率R>T(如何解释现象)

E属于断桥削弱，断的是桥：医疗条件R>T -----> 前列腺死亡率R<T

因为，根据E，不论是来自R，还是来自T的前列腺患者都由于不同原因没有接受良好的医疗待遇，所以结果就不一定会是前列腺死亡率R<T，现象前列腺死亡率R>T也有可能啊。解释了现象！

综上，Vote for E！

顶起来一起讨论！！
