1. 'mandates' is not a verb; it is used as plural noun and mandate is the singular noun; that is a relative pronoun here referring to the mandates and not as a subjunctive mood marker.
2. If the choice were to use the command subjunctive, then the construction--mandates that require utilities to increase--doesn't make much meaning. The correct structure then would be --state mandates that utilities require to increase --

A verb+ing participle, when not preceded by a comma will modify the noun it touches and therefore here, state mandates. The participle need not refer to the incentives in the context because while a mandate is obligatory, an incentive is more like 'take it or leave it' kind.

A. has been a combination of federal tax incentives and state mandates requiring utilities to increase the percentage of renewable power in their ---- "a combination- has been', "utilities-their" --- 'their' refers to the utilities --correct

B. have been combinations of federal tax incentives and state mandates requiring utilities to increase the percentage of renewable power in their ---- "a combination - have been "- SV number error

C. has been a combination of federal tax incentives and state mandates that require utilities to increase the percentage of renewable power in its --- 'utilities-its' --- pronoun number error

D. have been a combination of federal tax incentives and state mandates that require utilities to increase the percentage of renewable power in their --- 'a combination --- have been' - S V number error as in B.

E. has been a combination of federal tax incentives and of state mandates requiring utilities to increase the percentage of renewable power in its ---- 'utilities -- its' -pronoun number error

Hey daagh ,

Although I chose A, I just wanted to know why is "that require" wrong? Or is it even wrong?
I mean, just out of curiosity, if we replace "its" with "their", is C as good as A?

I don't think C is wrong because of the 'that require'; 'that require' smugly modifies the mandates and is as good as 'mandates requiring' as in A.
The problem as I see is in the pronoun 'its'. For that sake, if you change 'its' to 'their', then there would two correct choices leading to confusion.

Thank for the quick turn-around, daagh !!
I really admire your answers. You do not take things for granted and explain every single aspect, in great detail. You start from scratch, always assuming that the reader might be a beginner.
I owe all my verbal score to you!!

First of all daagh Thanks for sharing, great explanation.

Regarding the "it's vs their" IMHO It's refers to the country in possession of a portfolio. The state mandates are evicted by the state government to order a local government, and in this case are done to increase the production of renewable power, Federal regulation is not my field, but I imagine power is controlled by state government too.
So... I can't see how "their" can fit in the phrase, as portfolio is singular, and tax incentives and the mandates even if plural are clearly linked to "a combination" wich is singular (and can't own a share of renewable power portfolio)... even if the phrase could possibly refers to states, there should be a clearer reference for them, and there isn't any options for "states to own porftolios" in the choices.

So that leaves me with C as the only grammatically correct choice.

And finally, I found it on Veritas APP.

Cheers

Tricky Question

The primary catalyst fueling the rapid spread of wind farms across the country – from offshore platforms along the coasts through the vast deserts and plains – has been a combination of federal tax incentives and state mandates requiring utilities to raise renewable power to increasing percentages of their overall energy production.

A. has been a combination of federal tax incentives and state mandates requiring utilities to raise renewable power to increasing percentages of their

B. have been combinations of federal tax incentives and state mandates requiring utilities to raise renewable power to increasing percentages of their

C. has been a combination of federal tax incentives and state mandates that require utilities to raise renewable power to an increasing percentage of its

D. have been a combination of federal tax incentives and state mandates that require utilities to raise renewable power to increasing percentages of their

E. has been a combination of federal tax incentives and of state mandates requiring utilities to raise renewable power to increasing percentages of their

VERITAS PREP OFFICIAL SOLUTION:

As you first look at this problem, you should immediately identify two singular-vs.-plural Decision Points: the verb tense in "has" vs. "have" at the first word of the answer choices, and the fact that several choices end with either "its" or "their."

The first decision point, "has" vs. "have," requires you to find the subject of that initial verb. And while the problem throws several nouns at you via modifiers, the correct subject is "catalyst," which is singular. This means that "has" is required, helping you to eliminate B and D.

For the pronoun "its" vs. "their" at the end of the sentence, recognize that the antecedent is "utilities," since utilities are the only noun capable of having overall energy production. Because "utilities" is plural, you can eliminate "its" and answer choices C and E. Therefore, choice A is correct.

Based on SV Error, we can eliminate B,C & D. Out of A & E, A is correct because Combination of X & Y is correct Idiom, not combination of X & of Y. IMO

Hello all,

I agree with all explanation but something is changed in this thread which is different from given question.
Look at "to increasing" in underlined portion. As much as I know this is totally disastrous use of infinitive.

Where am I wrong?
