Claim: Potatoes are food.

Evidence: It turned black when I put iodine on it which means that it has starch in it which also means that it’s food.

Reasoning: I know that potatoes are food because potatoes have starch in them which is a nutrient and food needs to have nutrients to be food if it doesn’t it’s not food.
