Translate the following inference to logic notation: For all x, x_7 is not a scientist. There is at least one x for which x_7 is a soldier or x_7 is a scientist. For all x, x_7 is not a soldier. Therefore there is at least one x for which x_7 will read a book.
forall x: ~P(x). exists x: Q(x) or P(x). forall x: ~Q(x). Therefore exists x: R(x).
