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


Tell me what you think, and I'll give you the surprising answer

I will go for B

Does B has a typo - metabolisms(plural)?
If it is plural, then I will pick B. If not, I will pick A.

A is close call. But I think singular article(a) is wrong for metabolism.
C - metabolisms ... were more like metabolisms of mammal's metabolism - wrong

D and E are out because we need contend that

Pathik

I went for B, the answer is A. Tho I cannot 100% guarantee A is the official answer.

I think A is final. Metabolism cannot be "WERE" in B.

I have a pen just like yours. Sounds right...

The parallelism thing sometimes makes me think awry... >_<

this problem shouldn't be that challenging if you have a grasp of the very mechanical issues that commonly plague these sorts of problems.

in particular:
(c), (d), and (e) are all eliminated by their use of redundant language: since 'mammal's' and 'reptile's' are already possessives, there is no need for 'those of'/'that of'.

the poster above is correct about (b): the subject of 'were' is, ostensibly, 'metabolism', creating a singular-plural mismatch.

answer = a
