What purpose does paragraph 3 serve in relation to paragraph 2?

The choice indicating that paragraph 3 describes detailed information by giving specific examples and graphs is correct because it highlights how the text builds on the information presented in paragraph 2. If paragraph 2 introduces a concept or idea, paragraph 3 typically elaborates on that idea by providing concrete examples, data, and visual aids, such as graphs. This serves to enhance the reader's understanding by illustrating the points made in the earlier paragraph, demonstrating how theory translates into practice, or how general trends can be analyzed in specific instances. Such an approach helps to ground abstract ideas in reality, making the argument more compelling and easier for the reader to grasp.
