Stimulus Summary
Plants --most--> Flavonoids
Flavonoid in apple = Antioxidant
Antioxidants prevent heart disease
Answer Anticipation
The first clause is a broad one about plants and flavonoids, but it doesn’t really add to any of the other clauses. On the other hand, the second and third clauses build together to lead to an inference.
Apples have a specific type of flavonoid that is an antioxidant, and antioxidants are a factor in preventing heart disease. As such, apples (and the flavonoid they contain) can be a factor in preventing heart disease, so let’s find that as an answer.
Note that it says the specific flavonoid in apples is an antioxidant. That doesn’t guarantee any other flavonoid is an antioxidant, or that this specific flavonoid is present in any other plant!
Answer choices
-
AA diet composed largely Remaining source text redacted.
Why choice A is not credited
We know that apples contain a flavonoid that helps prevent heart disease, so a diet composed largely of that will help. However, a diet composed largely of fruits and vegetables might not contain apples, and other flavonoids might not help fight heart disease, so this answer is unsupported. -
BFlavonoids are essential to Remaining source text redacted.
Why choice B is not credited
Antioxidants are a factor in preventing heart disease, and one flavonoid is an antioxidant. That’s a far cry from supporting this answer - that all flavonoids are essential to preventing heart disease. -
CEating at least one Remaining source text redacted.
Why choice C is not credited
Eating an apple each day will get you an antioxidant flavonoid, which is a factor in preventing heart disease. That doesn’t mean that eating an apple a day guarantees you won’t get heart disease - it probably wouldn’t help much if you ate an apple and then 15 hamburgers every day! -
DAt least one type Remaining source text redacted.
Why choice D matches the stem
The flavonoid in apples is an antioxidant, and antioxidants are a factor in preventing heart disease. Thus, at least this one flavonoid helps to prevent heart disease, so this is the correct answer. -
EA diet deficient in Remaining source text redacted.
Why choice E is not credited
Antioxidants are a factor in preventing heart disease. That doesn’t mean that a lack of it causes heart disease. Tequila is a factor in someone becoming inebriated - that doesn’t mean a lack of tequila causes that person to be sober.
