How mach summary should include as much information possible?

A summary should be concise and include only the most important information. It should provide a brief overview of the main points, without going into excessive detail. The length of a summary will vary depending on the length of the original text, but it should generally be no more than a few paragraphs.

A good summary should:

- Be objective and unbiased.

- Use clear and concise language.

- Avoid unnecessary details.

- Focus on the main points of the original text.

- Be well-organized and easy to follow.

The ideal summary should leave the reader with a clear understanding of the main points of the original text, without the need to read the entire text.
