标题: GWD上的逻辑题 [打印本页] 作者: melody远行 时间: 2012-4-14 15:28 标题: GWD上的逻辑题 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. 有谁知道B选项是如何解释disparity的吗？我不太理解。感激不尽！作者: sdcar2010 时间: 2012-4-14 18:04
Apples against apples, not oranges.
This is a paradox question. The fact patterns are: 1) R has better healthcare than T 2) Death rate for prostate cancer is higher in R than in T
You are asked to find a reason that can explain both 1) and 2). If you pay attention to the above two facts, you would notice that both compare two region R and T. So the correct answer to solve this paradox has to dealt with both R and T as well.
Doe E) deal with R and T?
Does B) deal with R and T?作者: sdcar2010 时间: 2012-4-14 18:06
B) simply says those who would die of cancer in T are REALLY old people. Therefore their death would not decrease the average life expectancy number in T.作者: melody远行 时间: 2012-4-14 18:20
感谢！但是原文说的是percentage不是life expectancy作者: sdcar2010 时间: 2012-4-14 21:51
The question is a strengthen question, not a must be true type. Hence, if B) makes the conclusion more LIKELY, it is the correct answer.
