What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_5, if x_5 writes a letter, then x_5 is a musician. For all x_5, if x_5 were a musician, then x_5 is taking a plane. For all x_5, x_5 will not take a plane. There is at least one x_5 for which if x_5 were curious, then x_5 is writing a letter.
