请教一道parallelism的题-16og38题（diagnostic test）

pppjj

d选项:that dolphins have the ability of recognizing themselves in mirror——an ability that is often considered as a sign of self-awareness——and spontaneously grasping.
og解释说of recognizing和spontaneously grasping不平行，为什么不可以看成是recognizing和spontaneously grasping两者平行呢_(:з」∠)_想请教一下大神~
类似的结构像Fossils were found in a and b.和I want to eat, drink, and go to sleep.又是对的呀_(:з」∠)_有点晕

正常來說 看到ability+of Ving就該刪了(正確用法ability to V)

假設ability of Ving是正確的好了, 沒有 N of adv Ving

is considered as 见一次，打一次

除去楼上说的ability to 才是对的

recognising themselves 是动宾结构
spontaneously grasing 不是啊

谢谢两位！
