Debater's tip (Relevant, specific, reliable): Relevant: does it talk about the topic of the motion? Specific: does it say exactly who, what, where or how many? “30 of 40 students” beats “lots of students”. Reliable: can we trust where it came from? Records, textbooks and official bodies beat rumours and unsigned posts.
