@hannahnaylor5,

This stimulus presents you with lots of facts but no conclusion. You are looking for the conclusion that logically follows from the facts. What we know from the stimulus:

(1) The Kuna have a low incidence of high blood pressure.
(2) The Kuna on the mainland do NOT have a low incidence of high blood pressure.
(3) The Kuna on the islands normally drink lots of cocoa.
(4) The cocoa is high in flavonoids.

You're looking for a conclusion that can be reached based on the above facts.

Answers:
(A) is incorrect. There is no mention of availability of foods high in flavonoids in the stimulus.

(B) is incorrect. There is no mention of the Kunas' beliefs in the stimulus.

(C) is incorrect. The fact that Kuna on the islands and Kuna on the mainland have different levels of low pressure shows this is wrong.

(D) is incorrect. There is no mention of people other than the Kuna in the stimulus.

(E) is correct. This answer connects the various premises. The Kuna on the islands who drink lots of cocoa have lower levels of high blood pressure than the Kuna on the mainland who do not drink the cocoa. This leads to the conclusion that cocoa helps prevent high blood pressure.

Also, note that this is a "most strongly supported" question. You're not looking for a fool-proof conclusion, but rather one that follows logically from the stimulus.
