In statement–conclusion questions, a conclusion follows only if it must be true from the statement alone. Your own knowledge, guesses and "probably" do not count.
Rules
- "All who did X got Y" + "P did X" → P got Y. But "P did not do X" tells you nothing about whether P got Y.
- "Only those who …" works the other way round: getting Y requires X.
- Comparisons chain together: A > B and B > C give A > C.
- A conclusion that predicts the future, judges someone's effort, or talks about everyone in general usually goes beyond the statement.
