Passage Summary: You can't call a food 'nonfat' if it never had fat to begin with, unless people are confused; if you do label it that way, you have to tell them it's naturally fat-free.

Reasoning: The regulation prohibits 'nonfat' labels on naturally fat-free foods unless the public wrongly thinks they contain fat, and even then, the label must clarify that the food is naturally fat-free.

Analysis: To identify a violation, we need to find a scenario that breaks one of the two conditional rules provided. One violation would be labeling a naturally fat-free food as 'nonfat' when the general public is perfectly aware that the food is fat-free. Another violation would occur if the public is confused, the 'nonfat' label is used, but the manufacturer forgets to include the required disclaimer about the food's natural state. Focus on the specific conditions under which the label is permitted and ensure the scenario you choose ignores at least one of those requirements.
