Hi
GMATGuruNY,
One automobile manufacturer has announced plans to increase the average fuel efficiency of its sport utility vehicles by 25 percent over the next five years, amounting to roughly five miles per gallon, and representing the first significant change in the fuel efficiency of any class of passenger vehicle in almost two decades.
(A) amounting to rougly five miles per gallon, and representing
(B) amounting to rougly five miles per gallon, and it would represent
(C) an increase that would amount to roughly five miles per gallon and it would represent
(D) an increase that would amount to roughly five miles per gallon and would represent
(E) which is an increase amounting to roughly five miles per gallon, representing
Request your help to understand whether both Present participle modifier (amounting and representing) to convey result of preceding action "to increase"
and
Noun Modifier (an increase) are correct in the context of this sentence, other errors aside.
My reasoning is that ing is incorrect because:
1) plans for any one to increase - not necessarily the manufacturer. Indirect doer i.e. doer of increase not clear.
In this it would be helpful if you help with the role of "to increase"
If its an adjective modifying plans then => plans for anyone to increase (anyone is subject)
If its an adverb infinitive of purpose then => manufacturer is the implied subject. (In this case this reason for ing being incorrect is not valid).
2) Also the cause has not occurred yet for the effect to occur as represented by ING.
Can you help with this question.
TIA
