Why does Montag seem to struggle so much in trying to understand the books?

Also know, why is Montag trying to remember the Bible?

Montag compares his ability to remember the Bible verse to sand going through a sieve. Montag is only able to recall the words "Consider the lilies of the field" because the advertisement is so distracting. Montag becomes extremely frustrated with his inability to remember the entire verse and cries aloud on the train.

Similarly, what happens right before Montag and Mildred begin to read the books? Just before they start, the front door calls them to say there is someone at the door. They assume it is Beatty who has returned. There is one very important point that Beatty mentions when he is talking to Montag.

Similarly, what do you think Faber could have meant when he said that watching television feels more real than reading a book?

Faber agrees with Mildred that television seems more “real” than books, but he dislikes it because it is too invasive and controlling. Books at least allow the reader to put them down, giving one time to think and reason about the information they contain.

What seems to be wrong with Mildred?

Physically, the main thing that goes wrong with Mildred in Part One of the book is that she almost dies. She accidentally takes a whole bottle full of sleeping pills and is near death before Guy gets these guys to come over and pump her stomach and replace her blood.
