explain question

by jsasipriya » Wed Jul 28, 2010 4:58 pm
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.
22
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.
OA B

Why is it the OA?

The question you are trying to answer here is why do men in a country with good health care die more frequently of prostate cancer relative to men in another country without good health care?

What if it is the good healthcare that is, direclty or indirectly, causing the men with better healthcare to have prostate cancer. More directly, what if prostate cancer only afflicts the old? People in countries with good health care live longer, thus, you would expect to see more people with prostate cancer in a country with good healthcare than you would in a country with bad healthcare.

That is why the answer is B.

Hope that helps.

Option B is correct.

What if prostate affects only the old people?In Terland people do not live long enough to get cancer. People in Ruberia have a higher life expectancy because of better health care facilities. So old people in Ruberia are more likely to get cancer.

I agree that answer should be B. But are you sure that you have typed or copied question properly?

B compares men with prostate cancer to all men in Terland. However, which men who has prostate cancer? T or R?

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.

This is a resolve the paradox question, so the correct answer should explain how both scenarios came about. This answer addresses only Rubaria, and does not actually solve the paradox that exist in Terland, thus this cannot be the right answer.

You should practice to eliminate this pretty quickly on test day.

OA B

Why is it the OA?
It took me 2 minute to come to solution B. I too was strugglibg between B and E. Then I recalled the power score rule. This is explain the contradicting statement or resolve the paradox question.

powerscore rule says: Rule out all the answe choice which does not mention other side of the story. The correct answer choice should explain both the contradictions.

Answer choice E is wrong because it is talking and comparing ONLY the men in RUBARIA who take vs who do not ake advantage of health system. It does not talk or tell anything about teraland city.

Another answer choice that could have been added is people in Teraland have better genes than Rubaria and are less prone to prostrate cancer.


Answer choice B is correct: Tells us story of both side of the cities: Rubaria people who get this cancer are older than Tearland and hence death rate is higher.
