Heating-oil prices are expected to be higher this year than last becau

The pronoun “they” always jumps off the page at me, and in this case, it seems to refer to “refiners”, the most recent plural. That’s fine.

I’m also OK with the comparison: “refiners are paying… more for crude oil than they were [paying] last year.” I don't think that it’s ideal, but it’s definitely not wrong, and the GMAT would argue that the word “paying” is implied after “were.” Again, I’m not crazy about it, but it conveys the meaning clearly enough.

So let’s keep (A), I guess.


The phrase “expected to rise higher this year over last” is definitely a mess. You would never say that prices “rise higher.” They either just rise, or they just ARE higher. I’m also not sure why we would use “over last” instead of “than last.”

The placement of “more” is also really confusing. “More” modifies “pay about $5 a barrel”, and there’s no good reason to stick the word “more” so far away from the phrase it logically modifies.

But for whatever it’s worth: “they” still seems to refer perfectly reasonably to “refiners.” And the word “did” replaces the verb “pay” (or “paid”, since “did” is past tense). So those things are OK.

But I don’t think we can get over the silly placement of “more” and the "rise higher" mess at the beginning of the sentence. So (B) is out.


(C) has a couple of problems right in the beginning of the sentence. First of all, I can’t understand why we would say “expectations are for… prices to be higher this year.” That’s a horribly indirect way to say that “prices are expected to be higher.” The prices are the focus of the sentence, and it’s best if the prices are the grammatical subject of the sentence.

The comparison is also pretty goofy. “… heating-oil prices to be higher this year than last year’s…” The problem here is the possessive “last year’s.” We could say something like “this year’s prices are higher than last year’s”, or we could say that “prices are higher this year than last year.” But it makes no sense to say that “prices are higher this year than last year’s.”

So (C) is gone.


Like (C), (D) starts with an unnecessarily wordy expression: “it is the expectation that heating-oil prices will be higher this year…”. That’s not WRONG, exactly, but it’s definitely a crappier way to say “prices are expected to be higher this year…”

There’s also a problem with the phrase “higher this year over last.” You could say that prices were “higher this year than last”, but I can’t understand why we would use “over” in this context.

We also have an extra word that muddies the end of the underlined portion: “refiners are paying… more for crude oil now than what they were last year.” There’s absolutely no reason to include the word “what” in this sentence: “than they were last year” is enough by itself.

That’s enough to let us cross out (D).


(E) combines a bunch of problems that we saw in the other answer choices. “It is the expected” doesn't make any sense at all, especially when (A) gives us a much nicer option (“prices are expected to be higher…”). Also, there’s no reason to make “last year’s” possessive – see the explanation for (C) for more on this issue.

Finally, it doesn’t make sense to say that “prices will rise higher this year.” You could say that “prices will rise”, or that “prices will be higher”, but it’s redundant (and damned weird) to say “prices will rise higher.”

So (E) is out, and we’re left with (A).
