Reviving an old thread here.
D and E are clearly out as they change the meaning
Between A,B and C
(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
C is the right answer.
But I have one more query here:"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. "
in option A, we are saying that nuclear fusion is force that powers the sun , merging nuclei..... , as in nuclear reactorsthe nuclei is merging ... as it happens in nuclear reactors
But in option C, we are changing the meaning a little,
nuclear fusion is force that powers the sun , merging nuclei..... , as nuclear reactors do..Here the nuclei is merging ... like nuclear reactors
Isn't option A making more sense logically?
