B. On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth
这句话的实际主语是“the rate”，所以不应用“are”

E. Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow
倒装句，所以结构是"介词短语+谓语+主语"

on earth 到底在逻辑上应该修饰什么，是一处考点。
按照逻辑意思，应该是surest indications (of sunspot cycles) on earth，而不是it is believed on earth。

看了解释，还是想问问，后面的这个as seen ……是啥子成分啊？修饰的是

as这里是代词，意思是a fact that。

as...这里是同位语，同位the rate at which trees grow。
