Part Ill: Using rules of inference for quantified statements (50 pt.) Write each of the following arguments in argument form. Then, use the rules of inference to show that each argument is valid Let P(x) be x is a student in this class," Q(x) be "X does not own a car., and R (x) be "x takes the subway every morning," where the domain consists of all people. a. (15 pt.) Jack is a student in this class. Jack does not own a car. Everyone who does not 1. own a car takes the subway every morning. Therefore, someone in this class takes the subway every morning.
