week 5 qiz phi 103 Not P and Q It is not the case that P and it is not the case that Q It is not the case that P or Q It is not the case that P and Q 2. What is the truth value of the sentence "P v ~ P"? (Points : 1) True False Cannot be determined Not a sentence 3. "P v Q" is best interpreted as (Points : 1) P or Q but not both P and Q P or Q or both P and Q Not both P or Q P if and only if Q 4. Truth tables can be used to examine (Points : 1) inductive arguments. deductive arguments. abductive arguments. All of the above 5. A conditional sentence with a false antecedent is always (Points : 1) true. false. Cannot be determined. not a sentence. 6. One of the disadvantages of using truth tables is (Points : 1) it is difficult to keep the lines straight T's are easy to confuse with F's. they grow exponentially and become too large for complex arguments. they cannot distinguish strong inductive arguments from weak inductive arguments. 7. In the conditional "P →Q," "P" is a (Points : 1) sufficient condition for Q. sufficient condition for P. necessary condition for P. necessary condition for Q. 8. The sentence "P → Q" is read as (Points : 1) P or Q P and Q If P then Q Q if and only P 9. The truth table for a valid deductive argument will show (Points : 1) wherever the premises are true, the conclusion is true. that the premises are false. that some premises are true, some premises false. wherever the premises are true, the conclusion is false. 10. A sentence is said to be truth-functional if and only if (Points : 1) the sentence might be true. the truth-value of the sentence cannot be determined from the truth values of its components. the truth-value of the sentence is determined always to be false. the truth-value of the sentence can be determined from the truth values of its components.
