I do not claim to be an expert. But nevertheless, after following @nightblade354's advice for a CR strategy called the BlindReview, that is very well explained here
https://gmatclub.com/forum/mod-nightblade-s-quick-guide-to-cr-proficiency-295316.html#p2272709, I've experienced my CR accuracy go through the roof.
I have practiced an error analysis for each question. And this is my Analysis for this particular Question.
Quote:
Although nondairy coffee lighteners made with coconut oil contain 2 grams of saturated fat per tablespoon, or 7 times more than does whole milk, those lighteners usually contain no cholesterol. Yet one tablespoon of such lighteners causes the consumers blood cholesterol to rise to a higher level than does an identical amount of whole milk, which contains 2 milligrams of cholesterol per tablespoon.
Manufacturers of coffee lighteners based on coconut oil claim that their products usually cause the typical consumer’s blood cholesterol to rise to a lower level than does the use of whole milk as a lightener.
Which one of the following, if true, provides the most support for the manufacturers’ claim?
(A) Consumers of lighteners made with coconut oil who avoid other high-cholesterol foods and exercise more than average tend to have lower-than-average blood cholesterol levels.
(B) Coffee is frequently consumed with pastries and other rich desserts that themselves result in high blood cholesterol levels.
(C) One popular nondairy coffee lightener that is not based on coconut oil has reduced its fat content by 20 percent while keeping its cholesterol content at zero.
(D) Consumers typically add to their coffee substantially smaller quantities of coconut oil-based lighteners than of whole milk.
(E) Most consumers are convinced that whole dairy products increase blood cholesterol and that nondairy coffee lighteners do not.
I reduced the Premise and the Conclusion into a small Summary
Premise - Milk is actually supposed to be better in terms of low cholesterol levels.
Conclusion - Manufacturers claim that Lighteners are actually better, despite the superior cholesterol and fat content.
Why could this be? This is a Question that the strengthener could answer.
A. Says, a specific subset of the Lightener consumers exercise and avoid other high cholesterol food. Sure, this could help reduce cholesterol, but are we really concerned about what a small group of consumers does? Not Really.
OUTB. Says, Coffee is consumed a certain way. Okay, but what kind of Coffee? Lightner Based? Milk-based? And why does it matter that a bunch of other food is high in cholesterol content? Goner.
OUTC. One such lightener brand did something to reduce fat and to bring cholesterol to zero. Good intentions, but has nothing to do with the general scenario of why milk has to be worse than lighteners.
OUTD. Consumers typically add tp their coffee less amount of lightener than milk. Yes! Lighteners could be used in far smaller quantity than milk. Well known fact too. Also, this could have been important data for manufacturers to make their claim about their product.
CORRECTE. Most consumers are convinced that dairy products increase cholesterol lesser compared to milk. General Consumer perception doesn't matter here. This question is actually concerned with the manufacturer's claims.
