What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_10, x_10 is fast. For all x_10, if x_10 were a musician, then x_10 is not fast. There is at least one x_10 for which x_10 is a musician if and only if x_10 will read a book. For all x_10, if x_10 cooks, then x_10 is reading a book.
For all x_10, x_10 is not a musician. There is at least one x_10 for which if x_10 were a musician, then x_10 is reading a book. There is at least one x_10 for which if x_10 reads a book, then x_10 is a musician.
