What is the role of the conjunction operator in predicate logic?
- To combine two statements into a single statement that is true if both statements are true
- To combine two statements into a single statement that is true if either statement is true
- To combine two statements into a single statement that is true if both statements are false

What is the purpose of the implication operator in predicate logic?
- To establish a logical relationship between two statements, where the truth of the first statement implies the truth of the second statement

What is the purpose of a predicate in predicate logic?
- To express a property or relation that can be applied to objects in the domain of discourse

What is the difference between a term and a formula in predicate logic?
- A term is a logical expression that can be substituted for a variable, while a formula is a logical expression that can be evaluated as true or false
- A term is a logical expression that can be evaluated as true or false, while a formula is a logical expression that can be substituted for a variable
- A term is a logical expression that can be used to define a new logical operator, while a formula is a logical expression that can be used to establish a logical implication between two statements
- A term is a logical expression that can be used to negate the truth value of a statement, while a formula is a logical expression that can be used to combine two statements into a single statement
What is the purpose of a logical proof in predicate logic?
- To demonstrate the validity of a logical argument
- To define a new logical operator
- To establish a logical implication between two statements
- To negate the truth value of a statement
