Manhattan Prep Official Explanation:
The comparison in this sentence between undergoing a gastric bypass and to commit to a new lifestyle does not use correct Parallelism. To be parallel, the comparison should either be undergoing is committing or to undergo is to commit. Furthermore, neither instance of the Pronoun they has a clear antecedent, since there is no noun to which either they could refer. Finally, the not only X nor Y construction is unidiomatic; the proper Idiom is not only X but also Y.
(A) This choice is incorrect as it repeats the original sentence.
(B) Neither instance of the pronoun they in this choice has a clear antecedent.
(C) In this choice, undergoing is not parallel with to commit. Additionally, the plural pronoun they is incorrectly used to refer to the singular noun the patient. Moreover, the not only X but also Y construction requires X and Y to be parallel, but will no longer be permitted is not parallel to they will not be allowed.
(D) This choice incorrectly uses the unidiomatic not only X nor Y. Additionally, the plural pronoun they incorrectly refers to the singular noun the patient.
(E) CORRECT. This choice properly compares to undergo with to commit, correcting the initial error in parallelism. Additionally, the idiomatic phrase not only X but also Y is used correctly.
