Based on the growth rates of large modern reptiles such as the Galapagos tortoise and examinations of fossils of juvenile dinosaurs, scientists estimate that the largest dinosaurs probably lived to be between 100 and 200 years old.

(B) On the basis of growth rates of large modern reptiles such as

(C) Based on the growth rates of large modern reptiles like

(E) Based on such growth rates as those of large modern reptiles like

B for 2 reasons
1. Correct modifier " on the basis"
2. Use of "such as"

(A) Based on the growth rates of large modern reptiles such as

(C) Based on the growth rates of large modern reptiles like

(D) On the basis of growth rates of large modern reptiles, like those of

(E) Based on such growth rates as those of large modern reptiles like

"such as" cannot be right here. The X and Y here is "the growth rates of large modern reptiles" and "examinations of fossils of juvenile dinosaurs". Using "such as" makes this sentence unclear.

So, not A or B. E is wrong too, very awkward. So it is either C or D.
D is wrong because of the comma.
My pick is C. "Like" is correct here.

neeshpal,

Thanks for your explanation... what is wrong with A? can you explain.. I thought 'based on' sounded better than 'on the basis' ..

When use example, it should use such as. So eliminate C, D, and E. The idiomatic expression should be estimate on the basis of

"Based on" ---> here it looks like scientists are based on but actually their estimates are based.

In general but not always "based" is used for something physical and "basis" for abstract.

sentence wants to convey that the main reason behind their estimation is the growth rate .....etc etc..

so " on the basis" is used.

based on: Scientists estimation is based on the growth rates of ...etc etc..

such as is used for giving examples, hence C, D and E are out. A is wrong bcos bAsed on ...modifies scientists , this is wrong. B is the best choice.

Just taking a wild guess on whats wrong with A. In the first part of the statement we are using "the growth rates" whereas we are not using "the examinations" in the second part of statement. So is it breaking the parallelism. Experts please guide.
