What term refers to information that supports a main point in a text?

The term that refers to information supporting a main point in a text is text evidence. This is crucial in both writing and reading comprehension, as it allows readers to substantiate claims, arguments, or themes presented in the text. In academic writing, for example, using text evidence enhances the credibility of an argument by providing concrete examples and data that reinforce the main idea. This technique is essential in persuasive and analytical writing, as it ensures that the claims are not solely based on opinions but are grounded in textual support.

The other terms, while related to understanding and analyzing texts, serve different purposes. Implications refer to the suggestions or conclusions that can be drawn from a text but do not directly cite specific supporting information. Credible denotes trustworthiness or reliability, which is important when considering sources but does not specifically relate to the function of supporting evidence in a text. An index, typically found at the end of books, is a list of topics and their corresponding page numbers, which aids in locating information but does not provide evidence for text support.
