Rule: Find the paragraph's job before you judge any individual sentence. The right answer usually matches the exact task the paragraph is performing, not the broad topic it mentions.
- A paragraph can be about one subject and still have a narrower purpose, such as explaining how a program works or showing why a result matters.
- Summarize that purpose in one sentence before looking at the choices.
