I Agree to write Gmat is simple....hehehehehe....however when I see SC questions reality is something different....ok back to business....IMO B....D doesn't have specific subject in it.

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?
