Translate the following inference to logic notation: For all x, x_9 is a scientist or x_9 is a musician. For all x, x_9 will read a book. For all x, x_9 will go running or x_9 is not a scientist. For all x, if x_9 were a musician, then x_9 is running. Therefore Robert is reading a book.
forall x: P(x) or Q(x). forall x: R(x). forall x: S(x) or ~P(x). forall x: Q(x) -> S(x). Therefore R(a).
