Review It

When you analyze a text for meaning, citing evidence can help you to gain a deeper understanding of what you read. Authors include evidence to support and convey ideas in a text. You can use evidence to support your ideas about a text, to determine the author’s purpose, to support claims, to determine the meaning of words and phrases, and to answer questions about information in a text.

Evidence can be used to support explicit ideas in a text or to support inferences drawn from a text.
