The risk of fatal heart disease can be altered by certain
Why this is right
The soft language of "can be altered" is the primary reason why we'd try to fight for this answer choice. Did the passage mention certain lifestyle habits? Hmm, would we call smoking / drinking / exercise components of one's lifestyle? Sure, that seems fair. If we stopped smoking or stopped drinking or started exercising, that would seem to qualify as "a change in lifestyle". Could that alter our risk of fatal heart disease? Probably. After all, we know that these three factors influence blood cholesterol and blood cholesterol is tightly linked (Volume Dial relationships are the strongest possible form of correlation) to fatal heart disease / heart attacks. The Volume Dial relationship is not inherently causal. We could say, "the more birthdays you've had, the less of your lifetime remains" (depressing!) That doesn't mean that "having birthdays" is causing you to "have less life left". Both things are being caused by the unstoppable arrow of time. So why is LSAT cool with treating this Volume Dial as causal? 1) Partly, it seems to be just a little sloppy. This question stem should say Most Supported, and then it would be fine. 2) The first and third sentences contribute some context that makes it seem really likely that the relationship between blood cholesterol and heart disease is causal. The first sentence is saying that drug companies and health professionals are focusing on cholesterol in the blood (so it's implied that it would have some effect on health). The third sentence says, "the issue [of blood cholesterol's close link to heart disease] is pertinent since heart disease is the #1 killer". We probably wouldn't say that the connection between blood cholesterol and heart disease is pertinent unless we thought it was a causal connection. 3) Whether or not it's a causal connection, it's still given to us as a fact that "the less cholesterol you have in your blood, the lower your risk of fatal heart attack is". So if we know that changes to smoking / drinking / exercise could effect changes to your blood cholesterol, then according to the second sentence there would also be a change to our risk of fatal heart attack.
