Explanation:
A summary should be composed of the most relevant information that will help the reader to understand the main subject of the original text. Repetitive phrases, with little impact and information that are not relevant to understanding the subject such as "Many of the early residents lived in caves," can be omitted so that the text becomes smaller, but objective and more direct.
