Answer
Brief Explanations:
A concluding sentence summarizes the main idea of the paragraph. The underlined sentence "So, even though they live in water and look like fish, dolphins are still mammals" wraps up the paragraph by restating the key point that dolphins are mammals despite their aquatic appearance. A topic sentence introduces the main idea (the first sentence here: "Dolphins are mammals that live in water and look like fish"), and supporting details provide evidence (like giving birth to live young, giving milk, breathing air). This underlined part is a conclusion.
