The school’s having added art courses has benefited its students.

In this question, choice (A) uses wording that seems off to many people, “the school’s having added.” That wording is actually correct English .It’s a possessive + gerund structure, but many people are reluctant to choose choice (A) as correct because choice (A) uses that wording. However, there is a way to get this question correct even if we are suspicious of choice (A). We can eliminate all the other choices, which are not just odd but, rather, clearly incorrect. Once we eliminate all the other choices, we can confidently choose choice (A), even though it may “sound” a bit odd.

(A) The school’s having added art courses has benefited its This version may “sound” a bit odd to us, and we may wonder whether it’s correct, because it uses the wording “the school’s having added,” which is structured in an uncommon way. However, since that wording is not clearly incorrect, and since all the other choices are clearly incorrect, we can eliminate all the other choices and choose this one, which does happen to be correct.
