1. An outline is a plan made before writing; it helps organize ideas in order, remember details, and keep paragraphs clear.

2. Main topics are labeled with Roman numerals, like I, II, and III.

3. Supporting details are labeled with letters and moved slightly to the right (indented); the indent shows they belong to the main topic above them.

4. Taking care of a pet dog.

5. A. Feed the dog healthy food. B. Walk and play with the dog. C. Keep the dog clean and healthy.

6. Answers will vary; check that the student used a Roman numeral for the main topic and letters A, B, C (indented) for three details that genuinely explain that topic.
