求问 从句+平行

奔跑吧鸡麦特

"The results of two recent unrelated studies support the idea that dolphins may share certain cognitive abilities with humans and great apes; the studies indicate dolphins as capable of recognizing themselves in mirrors—an ability that is often considered a sign of self-awareness—and to grasp spontaneously the mood or intention of humans.

A. dolphins as capable of recognizing themselves in mirrors—an ability that is often considered a sign of self-awareness—and to grasp spontaneously

B. dolphins' ability to recognize themselves in mirrors—an ability that is often considered as a sign of self-awareness—and of spontaneously grasping

C. dolphins to be capable of recognizing themselves in mirrors—an ability that is often considered a sign of self-awareness—and to grasp spontaneously

D. that dolphins have the ability of recognizing themselves in mirrors—an ability that is often considered as a sign of self-awareness—and spontaneously grasping

E. that dolphins are capable of recognizing themselves in mirrors—an ability that is often considered a sign of self-awareness—and of spontaneously grasping"


这是og上对C、D的解释：c) a clause is required following the studies indicate; to be capable of recognizing is not parallel to to grasp spontaneously  
                                    d) have the ability of is wordy and unidiomatic; of recognizing and spontaneously grasping are not parallel.
有两个疑问：1. 为什么这里indicate后面一定要接从句 官方解释没给原因
                   2. 按照ron对平行的说法，从右向左判断平行  那么可以说spontaneously grasping和recognizing平行吗？
哪位做过路过的朋友能解答一下吗。。。感激不尽

1）句子的意思是：研究显示海豚有镜子中自我识别以及感知人类感情能力的事实。所以严谨的来说，indicate的对象应该是这一事实，而不是dolphins 或者ability.

2）D当中的平行是 of recognizing 和 grasping 的平行，但是介词结构和分词短语是不存在平行的，所以错

我觉得，按照ron的说法，D选项的平行是不存在错误的。
D问题是，have the ability of is unidiomatic. 正确的idiom是have the ability to
