不好意思。。。 我错了。。。。读题不认真，我没看见另外一个比较对象。E是不对的，无关比较。另外补充一下下。。。 本人男性
Q19:
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.
十分不理解，哪位好心人能讲解一下么，十分感谢~~
在R国，几乎全部的人都可以得到最好的医疗资源；在T国，只有少数的人可以得到足够的医疗
R国大多数的疾病死亡率都低於T国；但是男性死於prostate cancer的比率却是T国低於R国
选解决这个paradox的选项
我选C 差劲的医疗资源并不会增加得到prostate cancer的机会
A:加大prardox
B:无关选项
D:加大prardox
E:无关选项(隐含有加大paradox的作用)
薄见 大家一起讨论
可我读E的句意觉得是说：
在R，没有受到医疗系统照顾的人比有受到的人死亡率更高
这样是不是就变成强化原句中原本R的死亡率应该要比T低的矛盾了
还是我对E的理解有误 花杰MM再麻烦解释一下了
仔细看了一下，咱看看B哈： Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.
也就是说呢，T的人在得病之前就都圆满了。所以的病率不高。呵呵，B比较靠谱儿。让四楼GG见笑了
哈哈 花杰大哥 对不住了 是小弟眼背
明白了~~谢谢~~
明白了
Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.
意思大概是这样的，T的男的大约可以活到50岁就去世了，而R的男一般可以活到60岁以后，也就是说,T的男的去到50就会因为其它疾病死了，而不是死于P CANCER；而R的男的到60以后都没死于其它疾病，其它疾病都要不了他们的命，反而P CANCER成为了杀手。
就是说如果医疗条件都一样的话，60岁以后可能癌症死亡率是一样的。解释了原因
Being in poor general health does not increase one’s risk of developing prostate cancer.
虽然不会增加癌症，但也并不能说明为什么R的癌症死亡率高啊？最多就是2个国家都一样。
B，C can not explain the reason why the P cancer rate is higher in R.
C just says that P cancer is regardless with medical care
C is actually irrelevant. It is the death rate that is of concern
here.
Death rate = # cancer patients died / # all cancer patients
Risk = # people who get cancer / # people in the city
High risk does not indicate high death rate. High risk is related to
the cause of the cancer, genetic or environmental. Even if the risk of getting
the cancer is high, the death rate can be low if the cancer is mild form or the
treatment is well established. So C states a fact of truth that poor health
condition does not necessarily increase the risk of the cancer. But it does not
explain why the good health condition in R does not help decrease its death
rate.
B states that in general, the age at which people get cancer is
higher than the average life expectancy of T city. That means people in T city
do not live that long to get the cancer, probably because the poor health
condition there causes people to die of other disease before the age that most
people can get prostate cancer. In contrast, in city R, because people enjoy
better health conditions, and hence live longer until the age when they are
prone to get prostate cancer.
C如果把does not increase变成decrease就对了
B比较绕弯，也就是说那些在T国得cancer的人比平均寿命期望值的要老，也就是说要再往里想一层，老一点才能得那个cancer，T国health care条件差，大多数人活不到那么老，死人得不了cancer，因为得cancer人的基数要少很多，所以T国死于cancer的人比R国少。
总体上来说，这道题挺tricky的，因为B不是那么明显，C又长得挺像答案的，做对确实不易
