The sentence that sums up a paragraph's main idea is the:
- Closing remark
- Topic sentence
- Linking phrase
- Supporting detail
Show answer and solution
Correct answer: B. Topic sentence
1. A paragraph is built around one main idea.
2. A topic sentence is the sentence that summarizes that main idea.
3. A closing remark, linking phrase or supporting detail does not sum up the whole paragraph.
**Why not the others:** A closing remark ends the paragraph, a linking phrase connects ideas, and a supporting detail backs up the main idea.
