GWD-10-37

On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow, as seen in the rings visible in the cross sections of their trunks.

C On Earth, the rate at which trees grow is believed to be among the surest indications of sunspot cycles

E Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow

Why choose C?

Why not E?

请赐教！

on earth插在中间会引起歧义。

但我觉得C也不好啊，我觉得as seen in the rings visible in the cross sections of their trunks应该紧跟与trees相关的成分？

再请教一下！

忽然发现应该是sunspot cycles seen in the rings visible in the cross sections of their trunks

So it should be C.Right?

what is the subject of 'is' in E

In my opinion, it should be "the rate at which trees grow".
