Consider the following premises. For all x_15, if x_15 reads a book, then x_15 is a cashier. It is snowing if and only if Jessica is listening to a song. If Jessica listens to a song, then Jennifer is reading a book. Can we infer the following from them? If we can, name the inference rule being used: The fact that it snows does not imply that Jennifer is a cashier.
That contradicts the premises. Therefore the answer is no.
