求助 TPO14听力一道题

朝雨浥轻尘

就是那篇讲Passage Graves里的physical 现象那篇, 有一道题是重听了一段，大意是那种声音会使人心率加快、头疼、feel sick什么的，然后紧接着教授说了句That's the sort of the things, you see? 问题是最后一句什么意思，我选的是 she wonders if the explanation may be too difficult to understand 答案给的是she is confident that no more examples should be necessary
求解释！
