A polemical D interchangeable

后面说他们 yet hide了什么，因此前面是一定是努力说了什么，表达了什么
只能选F vocal

不是dissimilar 吗。。。shadowing 'difference' in the latter part of the sentence

对啊，同问。
应该是dissimilar吧，后半句说advertisements hide 其实重点是讲hide了candidate的difference，所以应该前面选dissimilar；而并不是说广告的沉默，所以该对应vocal吧？不然跟第一空的deceptive也对不上啊。
正确答案是什么？
