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.
R - excellent health care to all
T - adequate health care to few
Death rate for most diseases is higher in T than in R (Expected)
% of the male population that dies from prostate cancer is significantly higher in R than in T (Unexpected)
Why are the figures reverse for prostate cancer? Why are they worse for R than for T?
(A) Effective treatment of prostate cancer in its early stages generally requires medical techniques available in Rubaria but not in Terland.As per this, R's figures should be better then. It has effective treatment for this disease.
(B) Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.This tells us that average life expectancy of men in T is so short that they do not reach the age when they get susceptible to prostrate cancer. We know that healthcare improves life expectancy of people. As medical science progresses, people live longer and longer. They have cures for diseases and technology that helps give a longer life.
Say men are susceptible to it after 70 years of age. What if average life expectancy of men in T is only 65 years? People don't live as long in T because they don't have health care available. If they never reach the age of 70, they will not reach the age when they get susceptible to prostrate cancer. They would have died before reaching that age. They would have died because of whatever else but they wouldn't die because of prostrate cancer.
While in R, men must be living longer (because of healthcare facilities) and hence would easily reach the age of 70. After that some of them would get prostrate cancer and hence some deaths would occur because of it. This explains the discrepancy in the figures.
(C) Being in poor general health does not increase one’s risk of developing prostate cancer.Doesn't explain the reversing of the numbers in case of prostrate 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.As per this, R's figures should be better then. It has foods that decrease risk of getting prostate cancer.
(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.We are distinguishing between men in R and men in T. Why is the death rate due to prostate cancer in T significantly lower than that in R? If in R, men taking advantage of the health care system have lower death rate and those not taking full advantage have higher death rate due to prostrate cancer, then men in T must have the highest death rate due to prostrate cancer because they get no healthcare facilities.
It doesn't explain why T has lower death rate than R. Hence it doesn't explain the paradox.
