The best order for the sentences is: 3 – 4 – 1 – 2.
This order makes sense because:
- Sentence (3) introduces DeLuca's main question about whether rock lyrics are considered poetry.
- Sentence (4) provides DeLuca's assertion that the Nobel committee's award to Bob Dylan answers this question affirmatively.
- Sentence (1) expands on DeLuca's examination of Dylan's work and his literary contributions.
- Sentence (2) summarizes the evaluation of DeLuca's argument, acknowledging its convincing nature despite some confusion.
Thus, the orderly flow of ideas from the question to the evidence and evaluation is effectively maintained.
