In summarizing, it is important to include the key elements of the information being summarized. These elements are: who, what, when, where, why, and how. By including these elements, the summary provides a comprehensive overview of the subject matter, including the individuals involved (who), the actions or events (what), the time frame (when), the location (where), the reasons or motivations (why), and the methods or processes (how). Including all of these elements ensures that the summary covers all the necessary details and provides a clear and concise overview of the topic.
