So I think of a family I know like that, and then eliminate answer choices that are not true about the family I know. Reply

If P then Q If Q' then P' (the prime symbol means opposite of the statement, simply adding a “not”) E.g. If square then rectangle (p then q) If not rectangle, then not square (q' then p') Reply
