gmatissimple,(i love to write it. because it makes me feel that GMAT is simple for real)
Let me analyze it.
1. the army(singular subject) agrees with
is(singular verb)---> correct!
2. I noticed that there is
and in the middle of the sentence.
It seems that we need to know the usage of this
and.
I'd like to rule out b, c, and e because
- took 700,000 artisans more than 36 years to complete them --> pronoun error(the army --> it)
- took 700,000 artisans more than 36 years to complete it
- took 700,000 artisans more than 36 years to complete
- 700,000 artisans took more than 36 years to complete
- to complete them took 700,000 artisans more than 36 years --> no sense to use to complete after and
between b and d, I would like to pick b. because D there is no specific object. 700,000 artisans took more than 36 years to complete what?
what is OA please?
