GMATNinja, I did select B after being confused between B and E. The language if B is confusing.
Most men who have prostate cancer in Rubaria are older than the average life expectancy for male inhabitants of Terland. It may be obvious to others but it is not to me. Without the rephrasing I mentioned, it is unclear whether or not most men in Rubaria or Terland who have prostate cancer are the ones that are alive beyond Terland's avg. life expectancy. Let me know what you think. Thanks!
Let's start by taking a look at answer choice (B):
Quote:

As you suggest, this doesn't tell us anything
specifically about the age of men with prostate cancer in Ruberia OR Terland. So what exactly does it tell us?
Well, since it's talking about "most men who have prostate cancer," we can conclude it's talking about men
in general. In other words, most men with prostate cancer
in general -- whether they're from Terland, Ruberia, or somewhere else -- are older than the average male life expectancy in Terland.
Would this explain the discrepancy? Definitely. Because if men with prostate cancer tend to be older
in general than the average male life expectancy in Terland, then most men in Terland must be dying before they're old enough to get prostate cancer. So although Terland has bad healthcare, fewer men are dying there of prostate cancer. Why? Because most Terland men die of something else before they're even old enough to get prostate cancer.
Although (B) doesn't
specifically tell us about men in Terland OR Ruberia, it DOES tell us about men in general. And based on the reasoning above, it helps to explain the disparity.
I hope that helps!
