believed to be is the correct idiom.

I pick E

'Believed to have' is also a correct idiom.
In this case,B makes more sense as belief still exists...'to have'

(E) to be split

I vote B.

If it happened 5 to 20 million years ago, it's clearly in the past and won't happen anytime again.

"...it is believed to have" correctly addresses this issue.

If we say "...to be split..." wouldn't that mean it is split and continues today? I think the next phrase (5 to 20 million years ago) would indicate that is no longer the case.

This is just what the voices in my head are telling me..

I'd go with B as well.

A, D are out because "that" doesn't go with the sentence. , C is incomplete.

E makes is sound like the line of descent is split b/w 20 and 5 mil years ago, NOT split of descent between apes and human.

B. (i know its short, but plz underline the part in need of correction)

A. it split? the line of decsent... is believed... that it split??? wrong

C. to split... need present perfect to show a past action

D. they is ambigious and has no clear referent

E. to be split, in my time w/ the GMAT i have been told that to be is usually taboo on the GMAT. but, believed to be split... some time btwn 20 million and 5 million years ago... this construction is akward and requires a construction w/ past action
