In addition to the revised curriculum requested last semester, the students are now demanding that a new grading system be instituted.
(A) In addition to the revised curriculum requested last semester, the students are now demanding that a new grading system be instituted.
(B) In addition to the revised curriculum that had been requested last semester, the students are now demanding that a new grading system be instituted.
(C) The students are now demanding that a new grading system be instituted in addition to the revised curriculum they requested last semester.
(D) Added to the revised curriculum that was requested last semester by the students, they are now demanding the institution of a new grading system.
(E) Added to the new curriculum requested last semester, the students have now demanded the institution of a new grading system.
Choice A: This answer choice maintains proper tense and pronoun use throughout the sentence and conveys the intended meaning of the sentence. Thus, this answer choice is correct.
Choice B: This answer choice incorrectly uses the past perfect tense; the past perfect tense is used to refer to earlier of multiple events that happened in the past, and in this sentence, only one event is described as having occurred in the past. Thus, this answer choice is incorrect.
Choice C: This answer choice suffers from a very slight change in meaning; the phrase "instituted in addition to the revised curriculum" implies that the students are demanding that the new grading system be added to the revised curriculum, rather than the intended meaning that the students are making another separate demand for a new grading system. Thus, this answer choice is correct.
Choice D: This answer choice features a modifier error; the phrase "Added to the revised curriculum that was requested last semester by the students" modifies "they", referring to students. Thus, this answer choice is incorrect.
Choice E: This answer choice features a modifier error; the phrase "Added to the new curriculum requested last semester" modifies "students", implying that students were added to the curriculum. As this implication is clearly illogical, this answer choice is incorrect.
Hence, A is the best answer choice.To understand the concept of "Past Perfect Tense - Use of Had" on GMAT, you may want to watch the following video (~2 minutes):
