Without access to the specific text of "How AI Can Help Businesses Provide Customer Service," I can’t provide a precise answer. However, in general, if paragraphs 3–5 effectively transition between ideas about AI's applications in customer service or provide examples that support the central theme, option A ("They transition between two ideas") might be a reasonable choice.
If the paragraphs introduce a new concept related to customer service that enhances understanding of AI's role, then option B could be correct.
If the paragraphs seem to connect unrelated ideas without a clear relationship to the main theme, option C could apply.
If they argue against a potential criticism of AI's role in customer service, option D would be appropriate.
To determine the best answer, consider how those specific paragraphs relate to the central message of the text.
