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.

1. On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow
   
   
2. On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth
   
   
3. On Earth, the rate at which trees grow is believed to be among the surest indications of sunspot cycles
   
   
4. Among the surest indications on Earth of sunspot cycles, believed to be the tree growth rate
   
   
5. Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow
   
   
   
   看不明白题目是什么意思，主语是什么呀。。。。对于这个among开头的结构有些抓头
   正答是E

我是这么想的。
把选项E倒装一下，就是：The rate at which trees grow is among the surest indications on Earch of sunsport cycles.
(在把这个句子简化，The rate (at which trees grow) is the among the surest indications ( on earth) of sunsport cycle.

再看看A为什么不对：The rate 是单数的主语，所以复数谓语不对，淘汰。
再看看B为什么不对　多了一个it, 所以这个文章有多个主语，是fragment
再看看C为什么不对: 这里on earth 是壮语，放在句子的最前面有强调地点的意思。但是实际上这个句子是强调Rate的。
再看看D为什么不对：没有谓语，是Fragment

感谢楼上和楼上上~~对于我选错的那个答案..还是不太明白为什么错啊....难道是因为on earth放在前面没有放在后面做后置定语好？

c的话，划线的里面那个their的指代存在歧义，它最近的是sunspot cycles，逻辑逻辑上应该是trees,未划线部分的 as seen 应该要紧跟其修饰的名词。。。大概

这个among在这里什么意思？
