Supporting details enhance a paragraph by providing evidence and examples that clarify the main idea. These details serve to explain, prove, or illustrate the primary point being made, making the paragraph more informative and persuasive. When supporting details are included, they help to create a clearer understanding for the reader, allowing them to see how the evidence backs up the main idea.

For instance, if a paragraph discusses the importance of recycling, supporting details could include statistics about waste reduction, examples of recycling programs, or quotes from experts. This wealth of information strengthens the argument and makes it more convincing.

In contrast to the correct choice, introducing new topics and ideas would divert attention from the main point rather than support it. Summarizing the paragraph would not provide the depth or detail needed to enhance understanding. Additionally, adding too much information could indeed confuse readers rather than clarify the main idea, undermining the paragraph's effectiveness.
