Question

in an expository body paragraph, what is the most important role of the sentence(s) that come after a piece of evidence or a quote?
to transition the reader to the next body paragraph.
to explain how the evidence proves the topic sentence and what the evidence means.
to introduce a new, separate idea to keep the reader engaged.

Explanation:

In an expository body paragraph, after presenting evidence or a quote, the subsequent sentences should clarify the connection between the evidence and the topic sentence. This helps the reader understand the significance of the evidence. Transitioning to the next paragraph (first option) is typically done at the end of a paragraph, not right after evidence. Introducing a new, separate idea (third option) disrupts the flow of explaining the current evidence - topic sentence relationship. The second option focuses on the logical link between evidence and the main point of the paragraph (the topic sentence), which is crucial in expository writing.

Answer:

To explain how the evidence proves the topic sentence and what the evidence means.
