Consider the following premises. If Jessica were a janitor, then Robert is fast. If John reads a book, then Jessica is a janitor. For all x_13, x_13 will listen to a song if and only if x_13 will read a book. Can we infer the following from them? If we can, name the inference rule being used: The fact that John listens to a song does not imply that Robert is fast.
That contradicts the premises. Therefore the answer is no.
