Question

Two statements are logically equivalent when: The two statements agree in point of truth or falsehood in virtue of their logical structure alone, i.e. The two statement are true or false in exactly the same conditions. The first statement implies the second, i.e. If the first statement is true, so is the second. The two statements are true in virtue of their logical structure alone, i.e. The two statement are always true. The two statements are false in virtue of their logical structure alone, i.e. The two statement are always false. Which of the following is not a WFF? ((R^Q) v Z) ~P (((P > Q)^) R)(((P > Q)^R) An argument is [x] if and only if, when turned into an appropriate material conditional, there are no false lines under the MLO. An instance in which a line on the truth table for an argument is false, under the MLO, is called a [x].
