Even with the proposed budget cuts and new taxes and fees, the city's projected deficit for the next budget year is getting worse: administration officials announced that they believe the gap will be \$3.7 billion, a billion dollars over what it was predicted just two months ago.

A) over what it was predicted

B) over the prediction from

C) more than it was predicted

D) more than they had predicted

E) more than they predicted it

Doubt-

I am not able to decipher that why options C,D and E are wrong?

Let's look at the given sentence-

Even with x and y, the city’s projected deficit is getting worse: administration officials announced that they believe the gap will be \$ 3.7 billion, a billion dollars over what it was predicted just two months ago.

C) more than it was predicted

What does “it” refer to?

The gap?

In that case, the sentence would be-

Officials announced that the gap will be \$ 3.7 billion,  a billion dollars more than the gap was predicted just two months ago.

This doesn’t make sense.

Incorrect comparison. Eliminate

D) more than they had predicted

Correct

Officials announced that the gap will be \$ 3.7 billion, a billion dollars more than they had predicted

just two months ago.

Correct comparison - a billion dollars more than what they had predicted

“they” refers to officials.

Correct use of past perfect tense- had

Of the two actions, announced and predicted, “predicted is the earlier event (two months ago) and hence the use of past perfect tense.

E) more than they predicted it

Officials announced that the gap will be \$ 3.7 billion,  a billion dollars more than they predicted it

If it refers to the gap, the sentence would be-

a billion dollars more than they predicted the gap just two months ago.

Incorrect comparison.

Same as A.

Eliminate.
