Continuing the previous question, consider the same statement: VX & P, By @ P, Parent(x) + ParentOf(x, y) For this problem, we assume the following facts entirely describe the world: John is a parent Mary is a parent No one else is a parent John is a parent of Sally Mary is a parent of Joe No one else is a parent to anyone else There are no people besides John, Mary, Sally, and Joe. (That is, P = {John, Mary, Sally, Joe}.) Given these facts about the world, which of the following strategies proves the statement true? Hint: as usual, remember that -> here is logical implication. Keep in mind what makes an -> true! O If my adversary selects John, I will select Sally. Otherwise, I will select Joe. No matter what my adversary does, I will select John. No matter what my adversary does, I will select Sally. Although the statement is true, none of these strategies is correct. There is no successful strategy because the statement is false
