Between A, B, E....I pick "B".....altho I am not sure of the usage of "On the basis" vs "Based on".

Yes, I would appreciate if you could give more detailed explanations about "base on" and "on the basis of". I'm still confused about them. Thanks!

Do you C what is what is being modified In A? Ask yourself what is based on? Scientist ot the estimate ... it's is not clear in A... So A is wrong.

Where as in B.."on the basis" is modifying the "estimate made by scientist"

Does it help?

B)
Reason is simple:
X and Y: Both X and Y have to be parallel
We need to make the first part parallel to the second part after and i.e examination

For this we need a noun!
On the basis is Noun phrase

So On the basis wins.

Such as makes more sense than like as we are giving examples here.

Wow nocilis !! Your explanation seems plausible.

Could you explain a bit more..
"On the basis" is Noun phrase

Why "Based on" is adjective? which noun it is modifying?
Why "On the basis" is noun phrase? Is it not adjective similar to "based on" modifying scientists?

Thanks,

(B) seems fine.

1) "Based on" vs "On the basis of" - Based on conveys the meaning that the scientists were based on something. Whereas, "on the basis of" conveys that their findings were based on something.

2) "such as" vs "like": such as is used when arguments are quoted citing examples from the sample space. In this case, "the Galapagos tortoise and examination of fossils of juvenile dinosaurs".

go with B.
(A)(C)(E) based on is dangling
(D) the useage of like is no better than that of such as.

Ahh I got you. If the subject is the finding and not the people then it would be ok to use "based on" right?

OA is (B).
