Which statement best describes the role of a signal phrase in quoting?

• A. Introduce the quotation and attribute it to the source.
• B. Convey the credibility of the source by presenting its credentials.
• C. Set up the quote with context.
• D. Lead into the quotation naturally.

Answer: (B)

Signal phrases connect the reader to the speaker behind a quote by naming the source and attributing the words. They help establish who is speaking and, when credentials are included, why that speaker’s voice matters for the topic. Thinking about credibility this way explains why the option describing conveying the source’s credibility through its credentials captures the essential function of a signal phrase: it not only introduces the quote but also signals why the reader should trust it. While other aspects like setting up context or leading into the quotation are part of smoothly integrating quotes, the credibility angle is a distinctive and important part of what signal phrases accomplish.
