In the statement “No dogs are reptiles”, which terms are distributed?
Both subject and predicate terms
A term is said to be distributed when the proposition refers to the whole (every member) of the class denoted by that term. The statement "No dogs are reptiles" is a universal negative (E) proposition of the form No S is P.
In an E proposition, the subject term is distributed because the statement speaks about all dogs (every dog is excluded from being a reptile). The predicate term is also distributed because the statement excludes dogs from the entire class of reptiles (no dog belongs anywhere among reptiles). A standard rule is that the universal negative (E) distributes both its subject and its predicate.
Hence both the subject term (dogs) and the predicate term (reptiles) are distributed. The options naming only the subject, or only the predicate, or neither, are incorrect because they overlook the fact that an E proposition uniquely distributes both terms.
