Question

Please help me to understand the logic...

ssy84 · Answer

This questions tests both subject-verb agreement and parallelism.

The noun here is "a variety", which is singular. Hence, the verb to "include" must be singular as well - includes.

We can eliminate C and D.

Next, we look for parallelism in sentence structure.

E is out as "including" and "their use" is not parallel.

A is out as "their reducing" and "using is not parallel.

B is the correct answer as it contains the correct verb, "includes" and uses parallel structure by using "including" and "using".

Hope this helps!

The OA is C.

Identifying the subject is here is quite tricky. There's a rule that says:

"One of" + NOUN (plural) + Plural verb
e.g. One of the apples are bad.

"A variety of approaches" is similar to this hence the plural verb.

Subject is "approaches" which requires the plural verb "include."
Maintain parallelism by choosing "reducing...using...finding". Hence, answer C.

Also, "which" is proper vs "including" (option E) since "which" modifies the word "approaches". Use only the gerund (-ing) form of the verb to modify a phrase or a clause.

Hope this helps

The original sentence has 2 problems : 
1) A variety of approaches - is plural and so requires plural verb Include instead of Includes
2) Their reducing employment is awkward.

Also, looking at the non-underlined section of the sentence , it needs to parallel with ING form of actions.

C takes care of all these points .

TomB · Answer

I agree with LAKSH0328.

"approaches" is plural ,so we need plural verb "include"
 
 we need to maintain parallelism by using " ing " farm (reducing,using,finding)

answer should be c

Hi Denis, I actually discovered this while I was answering GMAT prep. I got the question wrong then researched the official answer in this forum or Manhattan forum. So I wrote it down in my Verbal rules notebook. I think though that this is covered by Gayathari's SC notes which I downloaded from the verbal forum here. Try downloading it from the verbal link or if you can't I can send it to you.

alchemist009 · Answer

the OA is C. the sentence has 02 problems i.e. parallelism and subject verb agreement. the subject of the verb "include" is approaches, the verb must be plural. hence A and B are out. using, reducing, and finding must be in a parallel form so D and E are out
