Answer:
I would say that the best answer for this question: Which rhetorical device is used in these lines, would be: hyperbole, or exageration.
Step-by-step explanation:
Rhetorical devices are mechanisms of figurative speech, used by writers to convey their message in the best way possible, while at the same time encouraging the flourishing of emotions and feelings in the reader, to ensure the best comprehension of it. There are many such devices to be used from, and sometimes, you can use several in a simple paragraph, but in this particular case, we have a hyperbolic use of language. The language used by the speaker, and the sense of desperation conveyed by the words, like "I haven´t time to think", or "Advertisements everywhere", gives you the idea that literally, this speaker is surrounded by selling people and papers, and it conveys a sense of urgency and despair at being so surrounded. This is why it is a hyperbole.
