After July, anyone disposing of or servicing refrigerators must capture the chlorofluorocarbons in the refrigerant chemicals.
(A) anyone disposing of or servicing
(B) those who dispose or service
(C) anyone disposing of or who services
(D) the disposal or repair of
(E) someone who disposes or repairs

Can you please explain why a is a better answer than c? While disposing of may be the correct idiom does not the "of" need to implicitly repeat after servicing since there is an "or"? ( conjunction)

Thanks

I think that A is better than C because A is more parallel than C. A uses two present participle to restrictively modify "anyone" whereas C uses one present participle and one clause to restrictively modify "anyone".

According to m-w.com, "service" is a transitive verb; hence, it must "connect" to its object directly without any preposition.

Shouldn't is be 'disposing off' ?

Only the main words need to be parallel - not everything else attached to each main word.

She likes eating hot dogs drenched in mustard and ice cream.

hot dogs and ice cream are both nouns and both represent things that we eat (which is necessary in this case, since it says she likes eating X and Y). I've described something extra about the hotdogs, but not the ice cream. That's okay - only the MAIN words have to be parallel.

Same here. Disposing and servicing are the main words and need to be parallel. Disposing also required the word "of" after it - you can't just say "disposing refrigerators." Servicing, however, has no such requirement, so no "of."

ETA: Just to make more explicit - you were saying that the "of" is implicitly repeated after "servicing." Strip it to the core.

"anyone <doing X> or <doing Y>"
the main thing going on in X and Y needs to be parallel, but things are not automatically implied or carried over from the structure of X to the structure of Y.

What is the wrong with E,

What is the basic diference between = ANYONE and someone

E has changed the meaning improperly. "Someone" means just one person. This sounds as though there is a specific person who will have to capture the chemicals.

"Anyone" indicates that this new law would apply to ANY person (including multiple individuals).

why should B be wrong?? i suppose it emphasizes more on who must capture ??

you don't "dispose things"; you have to dispose of things.

this doesn't seem like an official problem. is this problem actually from the gmat prep software?
