Consider the following premises. Joseph is an artist or it is snowing. For all x_10, if x_10 takes a plane, then x_10 is an artist. For all x_10, if x_10 were an artist, then x_10 is taking a plane. If it snows, then Joseph is taking a plane. Can we infer the following from them? If we can, name the inference rule being used: Mary is a scientist.
We cannot infer that from the premises. Therefore the answer is no.
