Translate the given statement into symbolic form. Be sure to define all pred- icates used. Use the variable a with domain D = {a : a is an animal } as your main variable. Then, negate the symbolic statement. In your answer, negations should appear only in front of predicates. Finally, rewrite the negated statement clearly in plain English. "Any animal that is wild can be tamed." 2.
