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
原文意思：地球上，在很多确定测算树木的生长速度的指标中，sunspot被认为是比较靠谱的一个，就像我们看到的年轮一样靠谱。
题目分析：A读完就不爽，on earth之后最好就别饶了，告诉我正事，还说among，没有说正事，杀，
B和A一样，杀。
C是rate被认为是indication了，反了，应该是sunspot被认为是树的indication，发起者不对，杀。
D的believe前面加了逗号，前面是among，其大概意思就是在一个东西中，那believe是谁干的呢？逗号前面根本就没说出一个主体来，是说在。。中（谁啊？不知道），发起者不明，干掉。
E前面几个选项所犯的错误都没有出现，虽然读起来语法结构乱七八糟的，就剩这1个了，选吧。（你要允许正确答案中的语法结构你分析不清楚，你又不是薄冰！）
