Which term refers to brief restatements of main ideas from a text?

The term that best refers to brief restatements of main ideas from a text is "summaries." Summaries condense the essential points and ideas, presenting the core message in a concise manner without including unnecessary details or examples. This allows readers to grasp the fundamental aspects of the original material quickly and understand the overall theme or argument being presented.

Insights, while valuable, typically refer to deeper understandings or interpretations derived from the original text rather than a straightforward restatement of its main ideas. Resumés, on the other hand, are documents summarizing a person's work experience, skills, and educational background and are not applicable in the context of summarizing text. Highlights are often points of emphasis or notable features from a text but may not capture the comprehensive essence of main ideas as effectively as summaries do.
