Some scientists contend that many species of dinosaur had a metabolism more like a warm-blooded mammal's than a cold-blooded reptile's.

A. that many species of dinosaur had a metabolism more like
B. that the metabolism of many dinosaur species were more like
C. that the metabolisms of many species of dinosaurs were more like those of
D. there were many species of dinosaurs that had metabolisms more like those of
E. there were many dinosaur species that had a metabolism more like that of

My major question here is can we or can we not eliminate that. Does anyone have a rule for when "that" can be eliminated?

thanks

A is best. B has wrong verb. "that" or "those" in C, D and E are wrong and unnecessary.

i am not sure which that you talking? in gmat sentence correction, if we look on only one aspect of problem, we cannot solve the problem. i believe in every problem there is a clue. if we can find the clue, then it would be easy to find the correct answer. lets see:

in this sentence, the clue is "a warm-blooded mammalâ€™s than a cold-blooded reptileâ€™s", which is possesive expression. this helps rule out some of the wrong answer choices such as C, D and E because these choices posses "than those" "than that" etc whoich are redundancy. B carries wrong verb "were", which is plural, where as we need singular verb for singular subject the metabolism.

All choices except A are wrong.

You need THAT after content to explain what the scinetists contend.

Possessive + those or that makes it redundant.

You cannot eliminate "that" in this case because one of the things tested here is the correct idiom for contend which is in fact "contend that".
In fact , "that" in the answer choices helps eliminate D and E as it is known that the correct idiom is "contend that.."
by the way, the answer is A

Hi guys thanks for getting back to me. I am not sure if i understand what you mean by possesive + that or those = redundancy

i dont see a "than those" in any anwer choice. also is A not a faulty comparison or is like a warm blooded mamal's imply that the metabolism of some dino's is like that of a warm blooded mamal's?

would appreciate some clarfication on the redundancy aspect
thanks

The rate of crime in city A is higher than that in city B -> is this wrong? it has a than + that contruction?

Is this better? can you omit the part int he brackets?

City a's rate of crime is higher than (that of?) city b's

your example is wrong. You are using possessive to express what in the first part.. You can not say "City a's rate of crime". If you do then tell me what does a's (expand it) stands for...

You use possessive usually to indicate the conjunction "of".

Whoa!! Am I the only one choosing B here. Please correct me, I thought, "many species of dinosaurs" was correct instead of many species of dinosaur. I thought B corrects this by using many dinosaur species. I agree that A is the shortest of all the choices, but is A the most appropriate??

Darth b is wrong because the subject and verb do not agree.

In the B, the subject is "the metabolism", which is singular and need a singular verb.

C, D & E uses “like those of” which is incorrect because it makes the link ambiguous, highlighted will be needed for the sentence to make sense.

..more like those of… a warm-blooded mammal’s than (those of) a cold-blooded reptile’s.

Can someone write the original question? What's all these strange letters around the words? I can't figure out if some words are in possessive or not. Bunuel pls or chetan2u pls

Hi Experts / chetan2u,

Some scientists contend that many species of dinosaur had a metabolism more like a warm-blooded mammal's than a cold-blooded reptile's.

A. that many species of dinosaur had a metabolism more like
B. that the metabolism of many dinosaur species were more like

OA- A

In option B S-V disagreement is the only error or there is some other reason also to eliminate it..?

Thanks

The other point is the ambiguity it creates....
as we are directly comparing the metabolism here..
the metabolism of A was more like B's than C's..

two cases-
1) the metabolism of A was more like B's than it was like C's..
2) the metabolism of A was more like B's than C's was like B's..

Whenever we are using a cognitive verb to show position ( maintain, contend, assert, etc.) we always need a that.

D and E out

the metabolism : singular ... B out

Between A and E

Those of a warm blooded animal or
... warm blooded animal's

those of a warm blooded animal's is pure redundancy.

C out

The subject "metabolism" and the verb "were" do not agree in number in option B

Hi Experts,

If we fix the SV issue in Choice B and write it as - that the metabolisms of many dinosaur species were more like.. -- Is comparing metabolisms to warm-blooded mammal's correct? Or does the possessive pronoun is always considered plural? Thanks much!

A) Correct.
B) "Metabolism" does not agree with the number of the verb "were."
C) "Those of" is redundant because "reptile" has an apostrophe.
D) "Those of" is redundant because "reptile" has an apostrophe.
E) "That of" is redundant because "reptile" has an apostrophe.

Yes, with SV correction, option B would be alright. The word metalbolism is omitted after the possessive "mammal's" / "reptile's". So comparison is between "metabolism" (of dinosaur) and metabolism (of hot-blooded reptiles / cold-blooded reptiles).

The possessive itself is not singular or plural - it is an adjective (possessive adjective) for another noun - that other noun could be singular or plural. You may say Ram's book or Ram's books. Both are correct.
