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.



A.On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow

B.On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth

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

D.Among the surest indications on Earth of sunspot cycles, believed to be the tree growth rate

E.Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow
答案选E，谁能解释一下E这句话是怎么看的。是不是有倒装在里面，那面正确的句子结构是什么？Among the surest indications on Earth of sunspot cycles是一个整体还是Among the surest/ indications on Earth of sunspot cycles？
此外，as seen in the rings visible in the cross sections of their trunks，这句话的逻辑主语是谁啊？

中文：树木成长的速率（可以通过观察树干的某个东西发现）被认为是世上最准确的太阳黑子活动周期指标。

此处among的用法不会有点诡异吗。。一般我们可以说
The princess is believed to be the prettiest girl.
The princess is believed to be among the prettiest girls.
is believe to be what！介词？
