Hello members,
I came down to A and E but I rejected E because I am not sure if we can consider heart disease as a subset of fatal disease.
I mean many other diseases can come under fatal disease. But the argument talks only about heart disease.
Kindly help and correct my reasoning.

GMAT Club Forum mobile appHi,
This is my approach (sharing because I got this question right well within 2 minutes). I try to choose an option which is LEAST WRONG, rather than a PERFECT ONE.
(A) Causal relationship is distorted. Yes, higher the cholesterol, higher the risk of disease. But there are N number of factors which can cause fatal disease EVEN IF cholesterol is ZERO. Therefore, based on the stimulus, we cannot say lower the cholesterol, lower the risk of fatal disease.
(B) Definitely wrong. Cannot deduce this based on the stimulus.
(C) High blood cholesterol is an issue, not high cholesterol diet.
(D) Definitely wrong. Cannot deduce this based on the stimulus.
(E) First things first. If heart disease kills people in NA, then it is fatal. To your second point --> Had it said, "The risk of fatal disease is DECREASED..", it would have been definitely wrong because we cannot deduce that from the question stem as heart disease is not the only fatal disease. However, based on the stimulus, we can definitely deduce that by making CERTAIN changes in the lifestyle (based on the 3 lifestyle factors mentioned in the stimulus), we can ALTER the risk. To help you imagine, let's assume someone is about to get mouth cancer because of tobacco and a heart disease because of smoking. And let's assume that lung cancer is more deadly. Even if this is the case, based on the stimulus, I can still say with confidence that risk of fatal disease can be ALTERED by CERTAIN changes in the lifestyle, without mentioning the nature of alteration.
Hope this explains.
