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.

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' :roll:

What's OA?

Thank you all,

The OA is indeed A!

But I still don't understand how "last" in
"Heating-oil prices are expected to be higher this year than last"
is enough to be compared with the "this year".
Wouldn't I need to say "last year" instead of "last"?

Example of ellipsis

Heating-oil prices are expected to be higher this year than last [year's prices] ----> Bulls eye

A is correct. "expected to be" is correct idiom. and "paying" is correct.

hence A.

C: is comparing expectations of this year vs the last year's. change of meaning. OUT

A it is.

Yes by the process of elimination we reach A.

Can some one explain what exactly are we comparing here and whether the things being compared are parallel.

IMO we are comparing the prices last year with the prices this year and the years.
From a parallelism perspective is A correct? If yes How?

Experts please comment.

Thanks

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 :lol:

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.

Can someone please explain why C is wrong. I thought the comparison is between this year's heating oil prices and last year's heating oil prices.

option C

Expectations are for heating-oil prices to be higher this year than last year's [heating-oil prices].....................correct comparison

option A

Heating-oil prices are expected to be higher this year than last [dont we need last year's heating-oil prices?]


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.

(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 because 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 for this year over last because refiners are paying about $5 a barrel more for crude oil now than what they were

(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

I have faced problems with these kinds of questions often...finally after reading Sara's note I am clear on how to handle these problems... would like to present a summary of my understanding to clear potential doubts in the minds of people who are struggling with these concepts...
---------------------------------------------
It is not correct to say -

HEATING OIL PRICES THIS YEAR ARE EXPECTED TO BE HIGHER THAN LAST YEAR – this way we are comparing heating oil prices of this year with the LAST YEAR (an illogical comparison) where as what we intend to compare are the prices of heating oil in each of the two years).

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)

Hi everyone .......

Thanks a lot for such a detailed explanation!! :P

There is just one thing that is still bugging me:-
In option 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" last year,

shouldn't there be "paying" AGAIN after "were" to make it as:
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 last year.

How can we hide "paying" ? Is this also ellipses ?? If so, kindly explain as i have NOT understood this well !!

Thanks so much

Hi tgtharvard,

Yes, this is ellipses. Since "paying" already appears in the sentence, there is no need to repeat it after the word "were".

Dear Sarai ....

Thanks for clarifying that ..... !!

And now that it is indeed an ellipses, please bear with me as i have another doubt that comes to light if option A is correct. Please help me with this one as well !!! ....... Sorry for the trouble!!!! :-

In the last part of this sentence:
Quote:
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.


Who does THEY refer to ????

Isn't it a case of unclear antecedent reference as "they" could refer to both "Heating-Oil prices" as well as "Refiners" ???

I know that the use of "were" makes it refer to "prices" but if we had used "did" instead of "were" it could as easily have referred to "refiners". In any case, the use of "were" or "did" doesnt stop "they from being called "an ambigios referrent", does it ?!?!
I hope i have made my doubt clear and not confused you all further !! :)

And if that is NOT the case, then could u please explain as to where am I faulting in my logic !!!!

Thanks a ton ...

Sam

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!!!

i did this question based on elimination, rather than selection.

you can straight away rule out c, d, and e because of the wordy nature of the sentences and the wrong grammar used.

from a and b, higher should be followed by 'than', so the OA should be A.

The options you suggested don't go with this construction of the sentence as the word
prices has been mentioned in the start of the sentence.

ps: if you give gmat prep's sc's, you'll find plenty of sc qsns which are not about the correct sentence/construction but finding the best of the lot.

A.

This is a comparison question I often have trouble with, but I will do my best to explain.

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.

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
Heating-oil prices are expected to be higher this year than (heating-oil prices were) last (year) Parentheses are omitted. - correct compoarison
Heating-oil prices are expected to be higher this year than last year's or last's (Heating-oil prices) -wrong comparison. We are comparing this year to last year.
If you want to use last year's, we must write
This year's heating-oil prices are expected to be higher than last year's or last's -correct

Let's say Heating-oil prices are just A. We can rewrite
A is expected to be higher this year than (A was) last (year). - correct
A is expected to be higher this year than last's (A) - wrong as this sentence is comparing this year to last year's A.
This year's A is expected to be higher than last year's/last's A - correct


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
Higher over is unidiomatic. Higher...than is correct.
rise higher is redundant.


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
are for heating-oil prices to be is wordy and confusing
last year's should be last year for the same reason mentioned in A.
are paying should be followed by they were


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
It is the expectation that is unnecessarily wordy. It is expected that is better.
'higher....over' is wrong. 'higher...than' is correct.


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
I think that you made a typo. Answer choice must be 'It is expected that' not 'it is the expected that,' which is correct.
rise higher is redundant.
last year's is wrong for the same reason explained earlier in answer A.

Why "they were" is correct in A? 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).

Ok - lets consider why others are NOT correct.

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. Higher than something is correct and not higher...over...[color=#4000FF][/color]

C) Expectations are for heating-oil prices(distorts meaning) to be higher this year than last year's becuase refiners are paying about $5 a barrel for crude oil more than they did. Clearly a run on sentence and is not preferred on GMAT.

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. (It is the expectation----(wordy) and higher....over is oncorrect too)

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. (It is the expected ---> incorrect . rise higher --> redundant words)

Please consider giving me Kudos if you think my post is useful to you!

Wonder why E is missing. Anyhow
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--correct comparison and no redundancy

(B) Heating-oil prices are expected to rise higher --rise and higher redundant
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 because refiners
are paying about $5 a barrel for crude oil
now than what they were --verbose and 'than what they were is redundant'.Heating-oil prices should be the subject of the sentence since we are mainly concerned with them

(D) 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--redundant 'rise higher'
