To find the answer to this question, we need to first understand what each term means.

- Direct object: It is a noun or pronoun that receives the action of the verb directly. In this case, "the grain of the western prairies" is not receiving the action of the verb but is acting as the subject.
- Indirect object: It is a noun or pronoun that indirectly receives the action of the verb. However, there is no indirect object in this sentence.
- Predicate nominative: It is a noun or pronoun that appears after a linking verb and renames or identifies the subject. For example, in the sentence "He is a doctor," "doctor" is the predicate nominative.
- Predicate adjective: It is an adjective that appears after a linking verb and describes or modifies the subject. For example, in the sentence "She seems happy," "happy" is the predicate adjective.

Given these definitions, the correct answer is "predicate nominative." In the given sentence, "source" is a noun that comes after the linking verb "is" and identifies or renames the subject "grain of the western prairies."

No.
