What does a summary include?

A summary is intended to provide a clear and concise overview of the text, capturing the main ideas and key details without extraneous information or personal interpretation. This succinct representation allows readers to grasp the essential points of the material quickly. By focusing on the core messages and critical elements, a summary omits subjective critiques, personal opinions, and detailed analyses, which are not integral to the purpose of summarization. Thus, the choice highlighting a brief overview of main ideas and key details accurately reflects what a summary encompasses.
