Cоnsider the fоllоwing аrgument where the domаin is the set of аll people: There is someone in this class who has been to France. Everyone who goes to France visits the Louvre. Therefore, someone in this class has visited the Louvre. Define predicates used in the argument above. (This argument can be expressed using predicates with a single propositional variable, example P(x), a Predicate with two propositional variables like Q(x,y) should not be necessary.) Construct the argument in symbols using the predicates you defined in part A. (Use the Equation Editor to facilitate the symbolic language).

Step Statement Justification 1 2 Clearly delineate parts A, B, and C in your answer.
