The correct element that should be included in a summary of a text is: the central ideas.
The correct answer is "the central ideas." When writing a summary of a text, it is important to include the main points or central ideas that the author is conveying. This helps to provide a concise overview of the text's content without going into too much detail. Including interesting metaphors or other texts on the same topic may not necessarily be part of a summary, as they are more likely to be specific details or additional sources that are not essential to summarizing the main ideas. The reader's conclusions, although important for personal reflection and analysis, are typically not included in a summary as they are subjective and may vary among different readers.
