Consider the following premises. For all x_11, x_11 is a cashier or x_11 is an astronaut. For all x_11, x_11 will climb a mountain or x_11 will read a book. For all x_11, if x_11 climbs a mountain, then x_11 is a sailor. For all x_11, if x_11 reads a book, then x_11 is a sailor. For all x_11, x_11 is not a cashier. Can we infer the following from them? If we can, name the inference rule being used: Sarah is not playing a game.
We cannot infer that from the premises. Therefore the answer is no.
