Flaw questions ask you to name what's wrong with an argument's logic; parallel reasoning questions ask you to find another argument with the identical flawed (or valid) structure. This lesson catalogs the recurring flaw types LSAC reuses across exams — such as correlation-causation errors and equivocation — so you recognize them by pattern rather than reasoning from scratch each time.
