The correct option is: <em>the reader could set his or her own pace and reread parts for clarity.</em>
When we read a text, we are able to do it in <em>our own pace</em>, <em>managing our time</em>, and <em>reading again</em> the parts we could not understand the first time.
On the other hand, <em>listening to audios</em> (or watching videos) can easily <em>affect our emotional perception</em> about a particular theme.
You have to tell/show us what the questions are if you want people to answer them
