Complete Question Explanation
Must Be True. The correct answer choice is (C).
This is a "most strongly supported" form of Must Be True question, so it's unlikely that we'll have a specific prephrase. Instead we need simply to document the strength/scope of, and reasoning relationships implied by, each of the stimulus statements.
The first statement states (with absolute certainty) a cause/effect relationship: that pollen in the air causes the immune system to respond with allergy symptoms.
The second statement states (with a lower level of certainty) that these allergy symptoms can be a result of inhaling large amounts of pollen.
The third statement compares (with absolute certainty) two ways of minimizing those allergy symptoms: staying inside on dry, windy days during allergy season is a more effective way to minimize allergy symptoms than taking medicines (which do, according to the sentence, "minimize those symptoms").
Answer choice (A): The stimulus does not provide information about the mechanism through which medicines minimize allergy symptoms, so we cannot know whether these medicines work by preventing the inhalation of large amounts of pollen.
Answer choice (B): The stimulus does not discuss which types of pollen (or how many types of them) cause allergy symptoms, thus this answer is incorrect.
Answer choice (C): This is the correct answer choice. Since we know that inhalation of large amounts of pollen can trigger allergy symptoms, and since we also know that staying inside on dry, windy days during allergy season is one way to minimize allergy symptoms (in fact a better way to do that than taking medicines), the stimulus strongly supports the idea that it is unlikely that those who stay inside on such days are inhaling large amounts of pollen.
Answer choice (D): The stimulus does not give any information about what people who take medication for allergies (or who stay inside because of allergies) tend to do or not to do, thus this answer is incorrect.
Answer choice (E): The stimulus does not discuss air filters at all, thus this answer choice cannot be supported.
