In Part Two, Montag boards a subway train headed towards Faber's home in hopes of learning how to comprehend the various texts that he has been reading from the former English professor. During the train ride, there is an extremely loud and annoying Denham's Dentifrice advertisement blaring through the speakers on the train car, which causes him to lose focus and prevents him from reading a verse out of the Bible. As Montag tries his best to read the passage aloud and comprehend the text, he is continually distracted and interrupted by the intense, loud advertisement over the train's speakers.
Bradbury emphasizes the overwhelming nature of the advertisement and illustrates how it affects the passengers on the train by writing, "The people were pounded into submission" (37). Bradbury's metaphorical comment highlights the oppressive, overpowering sound of the Denham's Dentifrice advertisement. The extremely loud and annoying advertisement prevents passengers from thinking, reading, or engaging in conversations with each other. Montag can no longer take listening to the overpowering advertisement and screams in frustration before sprinting off the train at the next stop.
