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 lighteners.

Which one of the following, if true, provides the most support for the manufacturers’ claim?

This is a strengthen type of problem.

(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.

exercise more than average this maybe the reason for lower cholesterol level not lighteners based on coconut oil. This will weaken the argument.

(B) Coffee is frequently consumed with pastries and other rich desserts that themselves result in high blood cholesterol levels.

Off the scope

(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.

Off the scope.

(D) Consumers typically add to their coffee substantially smaller quantities of coconut-oil-based lighteners than of whole milk.

This is the right answear , but very subtle.  The argument only mentioned about lighteners based on coconut oil and whole milk, but not the quantity of it. So, if you add less lighteners based on coconut oil than lighteners based on whole milk. It will actually strengthen the conclusion, it plays the role as a sufficient condition. We always have to put conclusion on the first place.
                

(E) Most consumers are convinced that whole dairy products increase blood cholesterol and that nondairy coffee lighteners do not.

Off the scope

无论是coconut-oil 还是 whole milk 都会引起血中胆固醇的上升，而制造商强调 前者引起的胆固醇的上升小于后者，那么顾客应该放心的多加一些coconut oil，因为多加一些，也不会引起胆固醇增加多过少量的whole milk.  这样才支持制造商的观点啊，困惑？？

這題沒有說「多加一點」，製造商是說，前者引起膽固醇上升小於後者，可安心使用。

但這不是跟前一題講的，「飽和脂肪引起的膽固醇上升比牛奶還高」相反嗎？因此，題目請你解釋一下是為什麼有這種說法（您若是GMAT考生，自然熟悉一種「explain」考題啦）。

答案D是說，因為加椰子油奶精（含飽和脂肪）時，消費者往往習慣加顯著少的量（比加牛奶顯著少），因此膽固醇上升變少了，能夠幫助解釋製造商說法。其餘選項則明顯無關，暫下不表。

我想NN的問題在於，看題時加進了自己的想法，認為有「多加」的意思在，但你看答案D，不是很明白說了，加得少膽固醇上升就少嗎？

Let analysis the argument:

(Premise)Manufacturers of coffee lighteners based on coconut oil claim that their products usually cause the (conclusion) typical consumer’s blood cholesterol to rise to a lower level than does the use of whole milk as a lighteners.

Which one of the following, if true, provides the most support for the manufacturers’ claim?

This is a strengthen type of question. It is strengthening the conclusion.

(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.

“exercise more” is never mentioned in the argument,  we only want to compare the coconut lightener and the diary lightener.

(B) Coffee is frequently consumed with pastries and other rich desserts that themselves result in high blood cholesterol levels.

Same reason as A, out of scope.

(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.

The argument is not about nondairy and none coconut based lightener, out of scope.
            

(D) Consumers typically add to their coffee substantially smaller quantities of coconut-oil-based lighteners than of whole milk.

Honestly, I do not like this answer too. It is like choose the least worst apple from a basket of rotten apples

Add smaller quantity of coconut based lightener will strengthen the conclusion that consumer’s blood cholesterol to rise to a lower level.

You have to remember that in this question you are ask to strengthen the argument, any answer that strengthen from 1% to 99% will do it.

(E) Most consumers are convinced that whole dairy products increase blood cholesterol and that nondairy coffee lighteners do not.

Totally out of scope
