og16 sc73 有一个问题没搞懂

亲爱的敌人

Researchers studying the brain scans of volunteers who pondered ethical dilemmas have found that the basis for making tough moral judgments is emotion, not logic or analytical reasoning.

(A) the brain scans of volunteers who pondered ethical dilemmas have found that the basis for making tough moral judgments is

(B) the brain scans of volunteers who pondered ethical dilemmas and found the basis to make tough moral decisions to be

(C) the brain scans of volunteers pondering ethical dilemmas and found that the basis for making tough moral decisions is

(D) volunteers’ brain scans while pondering ethical dilemmas have found the basis to make tough moral judgments to be

(E) volunteers’ brain scans while they pondered ethical dilemmas have found that the basis for making tough moral judgments is

A选项中who pondered ethical dilemmas have found如果这个have found的动作发出者不是researchers，而是volunteers呢？可以这样理解吗？如果这样理解那么A选项也就没有谓语动词而导致句子不完整


求大神解释一下啊！跪谢！

不能这样理解吧。
Researchers studying the brain scans of volunteers （who pondered ethical dilemmas） have found
who pondered ethical dilemmas是定语从句修饰 volunteers

不能这样理解。

假设have found的发起者不是researchers，那么发起者也只能是"brain scans"而不是"volunteers"

the brain scans (of volunteers) .. have found that ...

括号里的部分是修饰 brain scans的，brain scans才是中心词，“of volunteer”是modifier，不可以做动作的发起者。

brain scans have found that .. 不符合逻辑，因此不正确。

谢谢！懂了！我直接忽略了句子前面的成分，看成volinteers who````have found，把of结构硬生生拆开了
