Dear experts,

Please confirm if the use of increase and more is redundant in option A & B

Actually "increased" should be followed by an absolute number, not a multiplier. Therefore even if one says "increased by double", the sentence would be wrong.

However assuming that you ignore the above mistake, then "increase" and "more" are not redundant. The word "increase" refers to the number of cars and the word "more" refers to the number 2; "number of cars" and "2" are two different items.

The phrase "increase by double" and "increase by more than double" are equally wrong. The latter is not more wrong because of any additional error of redundancy.

sayantanc2k Why 'had'must not be used. One explanation I read somewhere cites that it is because only 1 verb is here. Can you please tell more on the same. *Clueless*

Thanks!

First, recollect that a past perfect tense is used to depict that an event occurs prior to another event in past.

In option E, the verb "had doubled" is in past perfect tense, but there is no reference of another verb with simple past tense in the sentence. Hence the reason above is correct - in order to use past perfect, you must have another verb in simple past ( or at least a time reference) before which the verb in past perfect occured.

VERITAS PREP OFFICIAL SOLUTION:

Explanation: In answer choice A, "twice," an adverb, is incorrectly used as the object of the preposition "by." Answer choice B introduces ambiguity by implying that the number of vehicles increased on more than two separate occasions, which does not make very much sense. Answer choice D uses the passive voice and suggests some unnamed agent (who did the doubling.) Answer choice E incorrectly uses the past perfect tense (had). "Had" is only used when verbs within the same sentence refer to different time periods. Because there is only one verb in this sentence, there is no use for the verb "had." The correct answer choice is C, which succinctly expresses the growth.

Hi mikemcgarry, GMATNinja, GMATNinjaTwo, daagh Experts

I did not get the verb for the subject number of vehicles in this sentence.

Quote:
The number of vehicles on the road classified as "light trucks" in the United States increased by more than twice from 1980 to 1992.

Although increased is seemingly the verb for number but I don't think it as a verb because number(S) can't do the action of increasing itself.
Please explain how is increased verb here also correct me where am I going wrong in the SV identification.
TIA.

A revisit to the functions and forms of various verbs may help to resolve the confusion.

1. Action verb--- Somebody does something and puts up some effort to do it. --- EX: Jack and Jill danced all day long

2. Linking verb: A verb that connects the subject with the predicate. It is called status verb, extant verb because it just indicates a status.

EX: Jack & Jill appear nervous. Here Jack and Jill do not do the action of appearing nervous.

3. Helping verb: This verb cannot act independently. It always combines with another verb to complete the meaning. Is, are, am, do, does, has, have, and being etc are few of the helping verbs etc

EX: Jack has been struggling with GMAT for nearly two years as he is finding the verbal tough.
In between, you will find that some verbs are both action and linking verbs. Examples of such dual verbs are:

EX: 1. appear 2.become 3.feel 4.grow5.look 6.remain 7.seen 8.smell 9.sound 10. stay 11. taste 12. turn 13. prove and some more.

EX: The musician increased the tempo in the last stage of the song.-- active voice.

The tempo of the music increased in the last stages. This verb has no doer, and it is a linking verb in the context.

EX: The ambient temperature increased from25 degrees to 35 degrees.

Take away: Do not expect a doer for every verb.
