Food labeling regulation: Food of a type that does not ordinarily contain fat cannot be labeled “nonfat” unless most people mistakenly believe the food ordinarily contains fat. If most people mistakenly believe that a food ordinarily contains fat, the food may be labeled “nonfat” if the label also states that the food ordinarily contains no fat.

Summary

The stimulus can be diagrammed as follows:

Notable Valid Inferences

If most people are aware that a food does not ordinarily contain fat, that food cannot be labeled “nonfat.”

Although most people know that bran flakes do not normally contain fat, Lester’s Bran Flakes are not labeled “nonfat.”

Does not violate. The regulation states that, if most people know that bran flakes do not normally contain fat, Lester’s Bran Flakes cannot label their product “nonfat.” Lester’s does not do so and thus is in compliance with this regulation.

Although most people are aware that lasagna ordinarily contains fat, Lester’s Lasagna, which contains no fat, is not labeled “nonfat.”

Does not violate. The regulation doesn’t describe situations in which a company must label a product “nonfat,” so Lester’s isn’t in violation by choosing not to do so. Note that “labeled ‘nonfat’” is a sufficient condition, so negating it (as (B) does) cannot yield a violation.

Although most garlic baguettes contain fat, Lester’s Garlic Baguettes are labeled “nonfat.”

Does not violate. The entire stimulus and the conditional logic it presents take place in the domain of “food that does not ordinarily contain fat.” This answer choice takes us out of the domain—if garlic baguettes normally contain fat, the regulation has no bearing on them.

Although most people are aware that applesauce does not ordinarily contain fat, Lester’s Applesauce is labeled “nonfat.”

Violates the regulation. As shown below, “most people mistakenly believe the food to be fatty” is a necessary condition of “labeled ‘nonfat’”. Since Lester’s Applesauce fails the necessary, it would have to also fail the sufficient in order to comply with the regulation.

Although most people mistakenly believe that salsa ordinarily contains fat, the label on Lester’s Zesty Salsa says “This product, like all salsas, is nonfat.”

Does not violate. As long as most people mistakenly believe that a food ordinarily contains fat, a company is allowed to label it “nonfat.” So Lester’s is in compliance with the regulation!
