Question 1 Multiple Choice (Single Answer)

What is the main difference between propositional logic and predicate logic?

  1. Propositional logic deals with statements that are either true or false, while predicate logic deals with statements that can be true or false depending on the values of their variables.
  2. Propositional logic uses symbols to represent propositions, while predicate logic uses symbols to represent predicates.
  3. Propositional logic is used to study the logical relationships between propositions, while predicate logic is used to study the logical relationships between predicates.
  4. Propositional logic is simpler than predicate logic.
Question 2 Multiple Choice (Single Answer)

What is a predicate?

  1. A predicate is a property or relation that can be applied to an object.
  2. A predicate is a statement that is either true or false.
  3. A predicate is a symbol that represents a proposition.
  4. A predicate is a variable that can take on different values.
Question 3 Multiple Choice (Single Answer)

What is a quantifier?

  1. A quantifier is a symbol that indicates the number of objects that a predicate applies to.
  2. A quantifier is a symbol that indicates the truth value of a proposition.
  3. A quantifier is a symbol that represents a variable.
  4. A quantifier is a symbol that connects two propositions.
Question 4 Multiple Choice (Single Answer)

Question 6 Multiple Choice (Single Answer)

What is the difference between a term and a predicate?

  1. A term is a symbol that represents an object, while a predicate is a symbol that represents a property or relation.
  2. A term is a symbol that represents a proposition, while a predicate is a symbol that represents a statement.
  3. A term is a symbol that connects two propositions, while a predicate is a symbol that indicates the truth value of a proposition.
  4. A term is a symbol that indicates the number of objects that a predicate applies to, while a predicate is a symbol that represents a variable.
Question 7 Multiple Choice (Single Answer)

What is a logical connective?

  1. A logical connective is a symbol that connects two propositions.
  2. A logical connective is a symbol that indicates the truth value of a proposition.
  3. A logical connective is a symbol that represents a variable.
  4. A logical connective is a symbol that indicates the number of objects that a predicate applies to.

Question 9 Multiple Choice (Single Answer)

What is the difference between a tautology and a contradiction?

  1. A tautology is a proposition that is always true, while a contradiction is a proposition that is always false.
  2. A tautology is a proposition that is sometimes true and sometimes false, while a contradiction is a proposition that is never true.
  3. A tautology is a proposition that is true for some values of its variables and false for other values, while a contradiction is a proposition that is false for all values of its variables.
  4. A tautology is a proposition that is true for all values of its variables and false for some values, while a contradiction is a proposition that is false for all values of its variables.
Question 10 Multiple Choice (Single Answer)

What is a model of a proposition?

  1. A model of a proposition is an assignment of values to the variables of the proposition that makes the proposition true.
  2. A model of a proposition is an assignment of values to the variables of the proposition that makes the proposition false.
  3. A model of a proposition is an assignment of values to the variables of the proposition that makes the proposition sometimes true and sometimes false.
  4. A model of a proposition is an assignment of values to the variables of the proposition that makes the proposition true for some values and false for other values.

  1. The completeness theorem states that every proposition that is true in all models is a tautology.
  2. The completeness theorem states that every proposition that is false in all models is a contradiction.
  3. The completeness theorem states that every proposition that is true in some model is satisfiable.
  4. The completeness theorem states that every proposition that is false in some model is unsatisfiable.

  1. The compactness theorem states that a set of propositions has a model if and only if every finite subset of the set has a model.
  2. The compactness theorem states that a set of propositions has a model if and only if the set is consistent.
  3. The compactness theorem states that a set of propositions has a model if and only if the set is complete.
  4. The compactness theorem states that a set of propositions has a model if and only if the set is satisfiable.
