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
(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 mammal’s than a cold-blooded reptile’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.

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..

Dear Friends,
Here is a detailed explanation to this question-
Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended core meaning is that many species of dinosaurs had a metabolism that was more like the metabolism of a warm-blooded mammal than the metabolism of a cold-blooded reptile.
Concepts tested here: Subject-Verb Agreement + Meaning + Comparison + Idioms + Awkwardness/Redundancy
• “contend + that” and "contend + with" are the correct, idiomatic construction.
• Comparison must always be made between similar things.
A: Correct. This answer choice correctly refers to the plural noun phrase "many species of dinosaur" with the verb "had", which can refer to both plural and singular nouns. Further, Option A correctly compares "a metabolism" with "a warm-blooded mammal's (metabolism)" and "a cold-blooded reptile's (metabolism)", conveying the intended meaning - that many species of dinosaurs had a metabolism that was more like the metabolism of a warm-blooded mammal than the metabolism of a cold-blooded reptile. Additionally, Option A correctly uses the idiomatic construction "contend + that". Besides, Option A is free of any awkwardness or redundancy.
B: This answer choice incorrectly refers to the singular noun "metabolism" with the plural verb "were". Further, Option B uses the passive construction "the metabolism of many dinosaur species were", leading to awkwardness and redundancy.
C: This answer choice incorrectly compares "the metabolisms of many species of dinosaurs" to "those of a warm-blooded mammal's (metabolism)" and "a cold-blooded reptile's (metabolism)"; the use of "those" alongside the possessive nouns "mammal's" and "reptile's" illogically suggests that the metabolisms of many species of dinosaurs were more like the metabolism of the metabolism of a warm-blooded mammal than the metabolism of the metabolism of a cold-blooded reptile; the intended meaning is that many species of dinosaurs had a metabolism that was more like the metabolism of a warm-blooded mammal than the metabolism of a cold-blooded reptile; remember, a comparison must always be made between similar things. Additionally, Option C uses the passive construction "the metabolisms of many species of dinosaurs were", leading to awkwardness and redundancy.
D: This answer choice incorrectly compares "metabolisms" to "those of a warm-blooded mammal's (metabolism)" and "a cold-blooded reptile's (metabolism)"; the use of "those" alongside the possessive nouns "mammal's" and "reptile's" illogically suggests that the metabolisms of many species of dinosaurs were more like the metabolism of the metabolism of a warm-blooded mammal than the metabolism of the metabolism of a cold-blooded reptile; the intended meaning is that many species of dinosaurs had a metabolism that was more like the metabolism of a warm-blooded mammal than the metabolism of a cold-blooded reptile; remember, a comparison must always be made between similar things. Further, Option D uses the unidiomatic construction "contend + clause"; please remember, “contend + that” and "contend + with" are the correct, idiomatic construction. Additionally, Option D uses the passive construction "there were many species of dinosaurs", leading to awkwardness and redundancy.
E: This answer choice incorrectly compares "a metabolism" to "that of a warm-blooded mammal's (metabolism)" and "a cold-blooded reptile's (metabolism)"; the use of "that" alongside the possessive nouns "mammal's" and "reptile's" illogically suggests that the metabolisms of many species of dinosaurs were more like the metabolism of the metabolism of a warm-blooded mammal than the metabolism of the metabolism of a cold-blooded reptile; the intended meaning is that many species of dinosaurs had a metabolism that was more like the metabolism of a warm-blooded mammal than the metabolism of a cold-blooded reptile; remember, a comparison must always be made between similar things. Further, Option E uses the unidiomatic construction "contend + clause"; please remember, “contend + that” and "contend + with" are the correct, idiomatic construction. Additionally, Option E uses the passive construction "there were many dinosaur species", leading to awkwardness and redundancy.
Hence, A is the best answer choice.
All the best!
