Question

Consider the following categorical proposition:

No books are buildings

This categorical proposition is:

		An I-type proposition
		An E-type proposition
		An O-type proposition
		An A-type proposition

Answer 1

No books are buildings is an E type proposition.

In categorical propositions, there are two parts such as, subject part and predicate part. When no subjects are predicate, then it is said to be an E type proposition as in the example. When all the subject are predicates, it’s supposed to be an E form proposition. For example, when all books are buildings, it’s an E form proposition. When some subjects are predicates such as, some books are buildings, then it is said to be an I form proposition. When some Subjects are not predicate, such as, some books are not buildings, then it is said to be an O form proposition.
