@kenken, happy to help!

The passage describes a study in which lower levels of lycopene are found to be correlated with a higher risk of stroke. The passage concludes that this must mean lycopene causes a reduction in stroke risk. In other words, it identifies lycopene as the cause and reduction in stroke risk as the effect. We are asked to weaken this argument.

(A) uses information introduced in the parentheses of the passage- that lycopene is found in some fruits and vegetables- to provide an alternative explanation for the reduction in stroke risk. By providing this alternate cause for the effect, (A) weakens the argument's claim that lycopene was the cause. You reference the point that we don't necessarily know the people in the study are getting their lycopene from fruits/veggies, but this does not eliminate (A) as the best answer. Remember, we are looking for an answer choice that could most weaken the argument. It is very possible (and even insinuated in the passage) that the people could be obtaining their lycopene from fruits/vegetables, especially since the study is looking at 1,000 people over 12-years and the only mention of where lycopene is found is in fruits/vegetables. Therefore, (A) is correct.

Does that make sense? Hope it helps! Please let us know if you have any other questions!
