Relative Costs

Kasia@MasterGMAT wrote:The key issue in this question is PARALLELISM.
Answer a is incorrect since the two phrases compared are different parts of speech. Also it sounds as if "the welfare program" resulted from the drop in costs. The correct structure should be "the welfare program's now costing"
Answer b - incorrect. The wording is exactly the same but "than" was replaced with "as." However, the structure is still wrong.
Answer c also contains the same mistake although the part of the sentence following THAN was corrected.
"resulting in the welfare program now costing about 3 billion real dollars less to implement than it did [cost]"
Answer d is correct.
Answer e is incorrect since it compares a clause with a prepositional phrase.

hope if you can elaborate that portion only.

Waiting for some expert to reply on this.

resulting in the welfare program now costing about 3 billion real dollars less to implement than

resulting in the welfare program now costing about 3 billion real dollars less to implement as

resulting in the welfare program now costing about 3 billion real dollars less to implement than it did

and as a result the welfare program now costs about 3 billion real dollars less to implement than it did

and the welfare program now costs about 3 billion real dollars less as a result to implement than

In A, B and C, resulting in the welfare program is incorrect. The welfare program was not the result. The result was its costing about 3 billion real dollars less. The correct construction would be resulting in the welfare program's costing about 3 billion real dollars less. (Please note that this construction would be grammatically sound but awkward and unlikely to be in the correct answer choice.) Eliminate A, B and C.

E incorrectly compares 3 billion dollars less to implement to in 1973. Eliminate E.

The correct answer is D.
