Nuclear fusion is the force that powers the Sun, the stars, and hydrogen bombs, merging the nuclei of atoms and not splitting them apart, as in nuclear reactors.
(A) merging the nuclei of atoms and not splitting them apart, as in nuclear reactors
(B) merging the nuclei of atoms instead of splitting them apart, like nuclear reactors
(C) merging the nuclei of atoms rather than splitting them apart, as nuclear reactors do
(D) and merges the nuclei of atoms but does not split them apart, as is done in unclear reactors
(E) and merges the nuclei of atoms, unlike atomic reactors that split them apart


Pls explain

going with C here is why:

what is the function of the underlined part of a sentence? to describe a clause "Nuclear fusion is the force" thus we need "merging the nuclei of atoms.." so D & E are out.

now, what is the gist of the underlined portion? to contrast how nuclear fusion operation different from reactor's: nuclear fussion merges atoms whereas reactors split atoms. the focus is on difference in actions (verbs) so "as noun/pronoun verb" construction is necessary.

C has it all.

C

merging.... - is logical form, and 'as nuclear reactors do' is needed

in B you are comparing orange with apple. Meaning a verb with noun.

B also have other issue, like should be used when you want to compare two nouns. here we are comparing verb with another verb so we need 'as'

IMO C, not B

splitting them apart Like nuclear reactors => splitting is an action. nuclear reactor is a noun. You can NOT use 'like' for comparison. It should be "splitting them them apart as nuclear reactors do" (D fixed this problem)

This is basically a contrast..the subject is Nuclear Fusion..
(A) merging the nuclei of atoms and not splitting them apart, as in nuclear reactorsIt shows that it is performing two action .. rather than emphasizing the contrast
(B) merging the nuclei of atoms instead of splitting them apart, like nuclear reactorsIt says that instead of doing X it is doing Y.. which is not the case..it is highlighting the contrast between two process
(C) merging the nuclei of atoms rather than splitting them apart, as nuclear reactors dohold....
(D) and merges the nuclei of atoms but does not split them apart, as is done in unclear reactors..hold..it says that it merges but does not split them apart.. as if both the process happens...in the process
(E) and merges the nuclei of atoms, unlike atomic reactors that split them apartNuclear Fusion is compared to atomic reactors.. apple and orange comparison.. ruled out...Also... it is the process in the atomic reactor which split them apart..while this says that the atomic reactor itself split them apart... out..
IMO .. C.. What is the OA?

Pls explain

Answer is C.
After POE, we are left with B & C.
B uses incorrectly "instead of" which is used to compare nouns.
C uses the correct usage "rather than" which is used to compare clauses & actions.

Confused b/w C and E. But finally went with E fr parallelism. But C is tempting as well. Can we have the OA pls?
