Final answer:
A simple predicate is part of English grammar and describes the main verb in a sentence, not boolean variables connected by boolean operators which is a concept from mathematics and computer science, hence the statement is false.
Step-by-step explanation:
The question asks whether a simple predicate is multiple boolean variables joined by boolean operators. This is false. A simple predicate in English grammar refers to the main verb or verb phrase in a sentence that tells what the subject does or is. It is not related to boolean variables or boolean operators, which are used in mathematics and computer science to perform logical operations. Predicates help us understand the actions or descriptions related to the subject of a sentence, and they can include verbs, objects, and additional descriptive information. However, they are different from Boolean logic where variables might be connected by operators like AND, OR, and NOT for the purpose of creating logical expressions.
