VERITAS PREP OFFICIAL SOLUTION:
Anytime you have a decision point between pronouns in the answer choices, you should start there. Here you must decide whether “it” or “they/them” is correct, so focus on numerical agreement. By carefully considering the meaning and structure of the sentence, it should be clear that the pronoun refers to the medical condition clonal hematopoiesis, which is singular. As a result, you can eliminate (A), (B), and (C).
To check logical meaning between (D) and (E), simply replace the pronoun with the noun it refers to and see if the sentence makes sense (a very important strategy in any SC problem involving pronouns). For (D): “…to reduce the increased risks of cancer or heart disease that clonal hematopoiesis confers” – YES. For (E): “…to reduce the increased risks of cancer or heart disease to which clonal hematopoiesis is conferred” – NO. The clonal hematopoiesis is conferring the risks and only (D) creates that logical meaning.
Correct answer is (D).
