Dear Responders,Thank you for your explanations. I would like to congratulate everyone for selecting correct answer choice and for giving brief explanation for the same.
Here is an official explanation from PowerScore
Stimulus can be broken down into three components
First :- Flavonoids are a common component of almost all plants.
Second :- A Specific variety of flavonoid in apples has been found to be an antioxidant
Third :- Antioxidants are known to be a factor in the prevention of heart disease
Before prephasing, take a moment to look at the connections among premises.
The Flavonoid connection between the first two premises proves to be non-informative. The first premise indicates flavonoids appear frequently in plants and the second premise cites a specific instance in apples.
The Antioxidant connection in the last two premises is more revealing. The second premise indicates that a flavonoid in apples is an antioxidant, and the third premise states that antioxidants are a factor in preventing heart disease.
Adding these two points together, we can deduce that the specific flavonoid in apples is a factor in preventing heart disease.
Since that statement must be true based on the premises, we can attack the five answer choices with this prephase in mind.
Choice A) Incorrect
The choice could be true
, but it is too broad to be supported by the facts: nowhere are we told that a diet of fruits and vegetables will help prevent heart disease. Perhaps apples are the only fruit with the antioxidants flavonoid and there is nothing beneficial about other fruits and vegetables. And, eating a diet of fruits and vegetables is no guarantee that the diet includes apples. Choice B) Incorrect
This answer is also a loser. Nothing in the stimulus supports the rather strong statement that flavonoids are essential
to preventing heart diseaseChoice C) Incorrect
The language of this choice is too strong: the stimulus only stated that apples contain an element that was a factor
in preventing heart disease, not that they definitely will
prevent heart disease.Choice D) Correct
This answer is closest to our prephase, and this is the correct answer. Notice how the language of this answer choice - "helps to prevent" - matches the stimulus language - "factor in the prevention."Choice E) Incorrect
This answer choice also could be true
, but it can not be correct because the stimulus makes no mention of the causes of heart disease. Just because an antioxidant can help prevent heart disease does not mean that a lack of antioxidants causes heart disease.Notice how the scope of the stimulus plays a role in how we attack the answer choices. The language of the stimulus is relatively broad - "almost all," "factor in the prevention," - and the author shies away from making definite statements.
Because the stimulus does not contain much in the way of direct, absolute information, selecting an answer choice that contains a direct, absolute statement is difficult to justify. This reasoning helps us eliminate answer choices (B) and (C), both of which contain strong statements that are ultimately unsupportable.
