A) Heating-oil prices are expected to be higher this year than last because refiners are paying about$5 a barrel more for crude oil than they were
B) Heating-oil prices are expected to rise higher this year over last because refiners pay about $5 a barrel for crude oil more than they did C) Expectations are for heating-oil prices to be higher this year than last year's becuase refiners are paying about$5 a barrel for crude oil more than they did
D) It is the expectation that heating-oil prices will be higher this year over last because refiners are paying about $5 a barrel more for crude oil now than what they were E) It is the expected that heating-oil prices will rise higher this year than last year's because refiners pay about$5 a barrel for crude oil more than they did

You've done a good job guys! Let me see if I can help you out with some of the confusion regarding comparisons and ellipses:

A. Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were What is compared here are the times-- "this year" and "last" (meaning "last year"-- this is an ellipses). When comparing time or place, you have two options for structuring the comparison: 1. Joe studies more at night that he does during the day. (The sentence compares Joe to himself.) 2. Joe studies more at night than during the day. (The sentence compares "at night" to "during the day.") B. Heating-oil prices are expected to rise higher this year over last because refiners pay about$5 a barrel for crude oil more than they did

Important Note!! The comparative structure requires that you use "than" after the "--er".

Correct: Tom is older than Bob.
Incorrect: Tom is older compared to/in comparison with/over Bob

You must use "than" after you've used a word ending with --er.

C. Expectations are for heating-oil prices to be higher this year than last year's because refiners are paying about $5 a barrel for crude oil more than they did You can stop reading as soon as you get to "for heating-oil prices" because that is not a correct description of the the expectations. The expectations are not for prices, but rather that prices will.... Important Note: Do not change a relative clause into a mere prepositional phrase!! Ex. "I think that chickens fly" (relative clause: that+subject+verb) IS NOT EQUIVALENT TO "I think of chickens flying" (prepositional phrase: of chickens) D. It is the expectation that heating-oil prices will be higher for this year over last because refiners are paying about$5 a barrel more for crude oil now than what they were

Same problem as B.

E. It is expected that heating-oil prices will rise higher this year than last year's because refiners pay about $5 a barrel for crude oil more than they did "prices will rise higher this year than last year's" uses ellipses that hide the logic problem. Complete everything that was left out, and the resulting sentence is: "prices will rise higher this year than last year's prices rose. This is not intended meaning of the sentence. Second, the word "more" is not correctly placed. Correct: I paid 5 dollars more for my sandwich today than I did yesterday. Incorrect: I paid 5 dollars for my sandwich more than I did yesterday. "More" describes$5 and must therefore be placed next to $5. _________________ Sarai GMAT Verbal Instructor at http://www.linkedin.com/company/ofek-gmat/online-gmat-tutoring-22305743/product?trk=biz_product Email me at saraiyaseen@gmail.com If this helped, kindly give Kudos!

So we must rephrase it as - HEATING OIL PRICES THIS YEAR ARE EXPECTED TO BE HIGHER THAN THE HEATING OIL PRICE OF LAST YEAR WHICH CAN BE ELLIPSED TO HEATING OIL PRICES THIS YEAR ARE EXPECTED TO BE HIGHER THAN LAST YEAR’S [PRICE] OR HEATING OIL PRICES THIS YEAR ARE EXPECTED TO BE HIGHER THAN THEY WERE LAST YEAR Another form similar to the one above is - THIS YEAR, THE HEATING OIL PRICES ARE EXPECTED TO BE HIGHER THAN THEY WERE LAST YEAR (NOT HIGHER THAN LAST YEAR) Or ellipsed form THIS YEAR, THE HEATING OIL PRICES ARE EXPECTED TO BE HIGHER THAN LAST YEAR’S [HEATING OIL PRICE] Now if we reword the whole sentence as below – (we have removed THIS YEAR from the first part of the sentence and positioned it AFTER the main verb (are) HEATING OIL PRICES ARE EXPECTED TO BE HIGHER THIS YEAR THAN LAST Now the comparison focus shifts from Price to Time frame (this year versus last) Manager Joined: 25 May 2010 Posts: 142 Followers: 131 Kudos [?]: 717 [4] , given: 0 Re: Heating-oil prices are expected to be higher th is year than [#permalink] ### Show Tags 11 Jul 2010, 03:51 4 This post received KUDOS 2 This post was BOOKMARKED Hi Sam, The issue of ambiguous pronouns is more a matter of logic than a GMAT 'trick'. If the pronoun has more than one logical referent, there is ambiguity. Ex. Computer A is next to computer B, and it is broken. In this sentence both computers are logical referents for "it". When you are presented with an ambiguous pronoun you will have trouble understanding what your sentence is saying. A correct answer will be a version of the sentence that is easier for you to understand because it is clearer. Ex. Computer A, which is next to computer B, is broken. In the problem at hand, "refiners" are the only word that make sense as the subject for the verb "were (paying)". Nothing else in the sentence has the ability to pay, so there is no problem with ambiguity here. Hope that helps! Lots of luck!!! -Sarai _________________ Sarai GMAT Verbal Instructor at http://www.linkedin.com/company/ofek-gmat/online-gmat-tutoring-22305743/product?trk=biz_product Email me at saraiyaseen@gmail.com If this helped, kindly give Kudos!

Why not they did? In-fact, should we be repeating the entire verb when we change the tense - Re: MGMAT SC? This is a very good question. The general strategy followed is, whenever you come across an ellipsis (ommitting a part of the sentence if there is no ambiguity) the best way to check is to complete the sentence and see if the verb is correct. Heating-oil prices are expected to be higher this year than last because refiners are paying about$5 a barrel more for crude oil than they were paying ...

Vs

Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they did paying ... As you can see the second version does not make sense (it should have been pay for did to be correct). However if the original sentence is reworded as Heating-oil prices are expected to be higher this year than last because refiners paid about$5 a barrel more for crude oil than they did pay ... => did is correct here. (I agree this version does not make logical sense , just for illustration purposes).

I do not follow the explanation for this question.

Can somebody please explain why this sentence is correct (original)?

Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were last year. My doubts are in these two phrases: "this year than last" and " more for crude oil than they were last year " Thanks!! Dear spc11, I'm happy to respond. My friend, you may find some answer to your question in the thread above, but I am happy to discuss this as well. One very tricky issue, particularly difficult for folks whose native language is something other than English, is the issue of dropping repeated words in the second branch of parallelism. See this blog article: Dropping Common Words in Parallel on the GMAT Consider an expanded version of the sentence: Heating-oil prices are expected to be higher this year than the heating oil prices last year because refiners are paying about$5 a barrel more for crude oil than they were paying for a barrel of crude oil last year.
That is the whole sentence, with absolutely nothing omitted, so that everything is perfectly clear. The GMAT would consider this completely redundant and much longer than necessary, because every single word in red is repeated. The words in red are words in the second branch or the parallelism that already appeared in the first branch. From the GMAT's point of view, it is redundant to repeat information in the second branch that we already know form the first branch. Thus, the GMAT recommends dropping all the words in red: when we do that, we get the prompt version, choice (A), of this SC problem, a sleek and elegant sentence. The GMAT loves elegance.

Your job on the GMAT SC is to see a sentence with the words already omitted in the second branch of parallelism and to figure out what words from the first branch would be needed to make sense of the second branch.

Does all this make sense?
Mike

A IMO
rise and higher together are redundant - B/E are out
last year's doesn't make a parallel consturction- C is out
and between A and D , D is wordy I think. Besides, using 'than' seems to be more correct than 'over'

What's OA?

Its clear we are comparing the heating oil prices of current year with the previous'

Refiners are paying the cruel oil prices not the taxes

You refine crude oil and get the heating - oil. Hence when the price of crude oil goes up then heating oil will become expensive.

Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were last year. _________________ Please press kudos if you like my post.
