请教！大全E-15，关于定于从句指代的问题；还有E-16，望NN指点！

15.   In good years, the patchwork of green fields that surround the San Joaquin
      Valley town bustles with farm workers, many of them in the area just for the season.

(A) surround the San Joaquin
     Valley town bustles with farm workers, many of them

(B) surrounds the San Joaquin
     Valley town bustles with farm workers, many of whom are

(C) surround the San Joaquin
     Valley town bustles with farm workers, many of who are

(D) surround the San Joaquin
      Valley town bustle with farm workers, many of which（A）

(E) surrounds the San Joaquin
     Valley town bustles with farm workers, many are

我把那个that理解成了修饰patchwork，我想请问定从前的of结构到底如何指代？？我觉得中心词是patchwork就应该指他。还是应该通过其他，比如逻辑意思判断？

感谢大家！

16.   John Smith provides information on the conditions that lead women to a gynecologist, and he notes that these conditions can, and sometimes are, used in the promotion of surgery which is not needed.

(A) and he notes that these conditions can, and sometimes are, used in the promotion of surgery which is not needed

(B) noting that these conditions can be, and sometimes are, used to promote needless surgery

(C) and notes that they could and sometimes are used unnecessarily in promoting surgery

(D) sometimes promoting needless surgery（B）

(E) which they use sometimes to promote unnecessary surgery

这道题我知道AC有大量错误，但我想问的是为什么这里使用伴随状语？大全解释是这里伴随状语比平行结构好，这个解释实在不足以解馋。如果把B的noting改为and he notes会选B吗？为什么？

谢谢大家～

顶起来！！高手帮忙～

我不是什么高手，

关于你的15题，答案是A吗？

我没看你说的那处，我是看后面，many of them 好像是同位语从句吗 或者独立主格之类的，所以后面是没有are的，我直接看了一个没有 are的选了。关于你说的patchwork 那个 还是 green fields，关于修饰与被修饰，应该提倡就近指代，所以你看到that从句应该首选是green fields除非十分不合逻辑，这处如果体会比较难，那还是尽量比较后面吧

16题，之所以用noting因为强调JS 提供信息和他noting是同时发生的 伴随状语就有这个功能，而其它选项加入and的强调先后顺序，notes被放在提供信息的后面不太符合实际的语义。所以即使按你说的把B改成那样 我也不认为可以。伴随状语在gmat里很常见 多留意和总结一下。

非常感谢MM的指导，呵呵，能将这么详细也算NN啦～

看来这个伴随和句子还是和逻辑意思有直接联系，因为做题掐时间，没有体会好，我再体会体会！
