Translate the following inference to logic notation: For all x, if x reads a book, then x is a taxi driver. For all x, x will read a book or x is not an electrician. There is at least one x for which x is an electrician. Therefore there is at least one x for which x is a taxi driver.
forall x: P(x) -> Q(x). forall x: P(x) or ~R(x). exists x: R(x). Therefore exists x: Q(x).
