Question

in a concluding statement, when a writer refers back to keywords, metaphors, questions, or other ideas from the introduction, what does the writer achieve? (1 point)

the writer makes the explanatory text feel complete.

the writer reinforces a message by showing how a particular expert agrees with them.

the writer asks the reader to take action or to think a specific way.

the writer shows the reader a wider impact behind the topic.

Explanation:

When a writer refers back to elements from the introduction in a concluding statement, it creates a sense of closure. This circular structure (referring back to the start) makes the text feel whole. The other options involve different techniques: reinforcing via an expert (which is citation - related), asking for action (a call - to - action), or showing wider impact (expanding on the topic). Referencing the introduction is about textual completeness.

Answer:

The writer makes the explanatory text feel complete.
