Inverse beta decay, the subatomic interaction by which an electron and a proton are "crushed" into a neutron, the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforming the stellar nucleus into a neutron star.

A. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforming

B. the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms

C. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and are transforming

D. is the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforms

E. is the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms

+1 for D.

A. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforming --> Incorrect

B. the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms --> Incorrect

C. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and are transforming --> Incorrect

D. is the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforms --> Correct

E. is the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms --> Incorrect

Hence, D.

the stellar nucleus into a neutron star.

A simple S -V error and style question that exposes the intimidating verbiage need not be a big issue in SC. The subject is the singular decay and both the verbs should be singular with a proper conjugation.

A. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforming - Transforming is no verb; hence, the second part is a fragment.

B. the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms --- 'are pushing' --S-V error

C. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and are transforming -- are transforming-- S-V error

D. is the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforms --- correct

E. is the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms --- are pushing --- S-V error

A. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforming
the beginning must start with a verb. Otherwise "Inverse beta decay" will "dangle" alone, hence A is out

B. the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms
the same as A

C. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and are transforming
the same as A

D. is the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforms
seems to be correct, so keep it

E. is the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms
not parallel, hence out

We got D as an answer.

Official Explanation

A question about the role of inverse beta decay in a supernova.

Notice that this sentence begins with [noun] + [noun modifier]. The noun, “inverse beta decay,” is the subject and needs a verb. Choice (A) never provides a verb for this subject—the famous missing verb mistake!—so it is incorrect.

Choice (B) has parallelism issues inside the “that” clause. It has “push out . . . and transforming,” a full verb in parallel with a participle. That’s a parallelism mistake. This choice is incorrect.

Choice (C) inexplicably has the present progressive tense, “is pushing.” This tense is completely incompatible with the context. This choice is incorrect.

Choice (D) has correct parallelism and it is well-organized. Notice that, while “who” and “whom” always refer to people, the possessive pronoun “whose” can apply either to people to inanimate things. Here, it’s perfectly correct in applying to “process.”

Choice (E): Problem #1—on the GMAT, the word “where” should apply to real physical locations; the GMAT frowns on applying “where” to abstract ideas, such as “process.” Problem #2—the noun “recoil” is singular, and the parallel verbs “push … and transform” are plural. While the parallelism is flawless here, that’s a SVA error. This choice is incorrect.

The only possible choice is (D).
