C is wrong.

Thanx to --> Stacey Koprince (mgmat forum)

An inversion is when the subject of the sentence comes after the verb. In many of the choices, this occurs. If we look at A, we have the following prepositional phrases:
"on earth"
"among the surest indications"
"of sunspot cycles"

Prepositional phrases don't contain the main subjects of sentences, but these are the only words before "are believed to be" - so the subject must come after the verb.

What is or are believed to be? If I strip it down: The rate is believed to be among the indications...
I agree it sounds kind of weird, but it's grammatically correct.

As for C, it implies first that this belief is only true "on earth" - but maybe people living on other planets have different views. That's nonsensical. The ending "indications of sunspot cycles, as seen in the rings visible..." also implies that the rings are in the indications of sunspot cycles (the stuff after the comma modifies the stuff before the comma). That's also nonsensical - we see evidence of the tree growth rate in the rings, not sunspot cycles.

HI

CAN ANY ONE EXPLAIN WHY C IS WRONG

E it is

C is wrong because in the non-underline portion "their" should refer to trees and not sunspot cycles.
