E

as seen紧接trees grow 

sunnyfields

个人觉得E更好，因为后半句

as seen in the rings visible in the cross sections of their trunks.

应该直接连在rate at which tree grow 后面，而不是连在surest indications of sunspot cycles后面

sunnyfields

补充一点，后面出现一个代词their trunks，指代trees，C选项的trees在句首，距离太远，当中隔了sunspots, indications等复数名词，显然有指代不清的问题，所以E更好。

谁能帮忙具体分析一下为什么C不对啊？

forgetviviva

the rate on earth? or "the rate is believed to be among...." on earth? not logical

A B C wrong for sure

forgetviviva

E has a full stentance followed by as seen. which makes sense to me....

做题的时候直接把E去掉了，因为没有主语

E主语是rate么？是倒装么？由于among引起的么。。。实在看不明白
