In any case, to wear an improper expression on your face (to look incredulous when a victory was announced, for example) was itself a punishable offence. There was even a word for it in Newspeak: FACECRIME, it was called.

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.
