D for me,

A, B, C give the impression that only the "conservation projects" will be responsible for high cost.

so Down to D and E .

E is out because of wordy ness and use of "so that" ..

what's OA And OE ..?

Beerster · Answer

By POE, I'll go with D too, except the use of "whose" bugs me.......

allabout · Answer

I think D is best.

Whose is correct, because it is placed next to the noun it refers to.

vivek123 · Answer

Yes, good job guys, OA is 'D'

b14kumar · Answer

Late arrival.

I am also going with D.

princeofshanghai · Answer

propose has to go with will right???

I would have picked C because at a cost is idiomatic but Propose something will raise is correct vs Propose something that raises

is it good to attack this question this manner?

rlevochkin · Answer

C w/o a doubt.

1) at a cost is idiomatic.
2) in this situation, it's better to use which + simple verb tense than an -ing verb.
Edit: shoot! In C, the word "which" modifies conservation projects. therefore, it's incorrect. Hopefully, I won't overlook that one on real GMAT test.

GMATT73 · Answer

Late, but (D). "Projects" can be restated with the possessive pronoun "whose"

shahnandan · Answer

D for me as well, was a little sceptical about "whose" there but considering that it succeeds the noun it refers to I guess its fine
