Arguments and evidence
Strategy card
A good argument gives a reason that really supports the claim.
- Step 1: Find the claim: what is the person saying?
- Step 2: Find the reason: why do they say it?
- Step 3: Ask: does the reason really prove it?
- Step 4: Pick the answer that best fits the question.
Tip: Words like "because" and "so" point to reasons and claims.
