Analyze the following categorical proposition by doing the following: (1) Identify the subject and predicate of each proposition
spayn [35]

Answer:

(1) Subject term: Bats and Predicate term: Mammals.

(2) A- Proposition

Step-by-step explanation:

Categorical proposition is a tool of deductive reasoning that involves two classes of objects. Coined by Ancient Greeks, categorical proposition asserts or denies whether one group contain all or some of the members of another group.

In the standard form of categorical proposition, the subject term comes first an the predicate term comes second. Hence, for the given sentence

<em>                                    </em>    <em>"</em><u><em>All bats are mammals</em></u><em>"</em>

The subject term is "bats" and the predicate term is "mammals". Furthermore, it is stated that all bats belong to the category of mammals. Thus, it is an example of proposition A(All S are P).
