A 500/550 level

Thunderstorms form when warm,............WHAT should be your question ?? after that becasue, no matter what is followed, has no sense.

What follows is either

Now: in D the construction is not clear and being is always 99% of times is wrong

E has: the right idiom either /or; it also has a parallel structure : either becasue / or because. when either/or (or others such construction quite similar as : neither /nor) is followed by a word, it must be repeated after or. If the word is BEFORE either, after or is not needed to be repeated.

hope it is clear

Why is D wrong ? IMO because of followed by a verb is wrong, as in option D contains verb "being". Please let me know if my reasoning is correct

Hello.

D is wrong because:

1. "ground's being warmer" = ground is being warmer. Why we use present continuous? Present simple is correct.

2. Because of + noun/noun phrase. But the "second" because of + clause (because of the interaction of two air masses, one warm and one cold, forces warm air to rise.). That's wrong.

Hope it helps.

So does that mean because of +"clause" is permissible in GMAT ? I am under the impression that because of+"Noun or Noun Phrase" is the only permissible structure
