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.

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.
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.

Answer:B

I choose E, I dont know why B is right, can somebody explain it?
