Answer:
Subject(S) - Mom
Verb(V) - made
Indirect Object(IO) - Sue
Direct Object - a birthday cake.
Step-by-step explanation:
A sentence usually consists of a subject followed by a predicate which includes a verb along with other elements to complete the predicate(verb, object, etc.). In the given sentence, 'Mom' is the subject as she performs the action of the verb and she is the one the verb is enacted upon. 'Made' exemplifies the verb as it indicates the action of the subject. 'Sue' illustrates the indirect object which is affected by the action of the verb(transitive) while 'a birthday cake' is the direct object that is primarily receiving the action of the verb.
