Consider the following premises. If Charles were a carpenter, then it is raining. For all x_12, x_12 is a carpenter or x_12 will play squash. If Charles plays squash, then it is raining. If Mary were an artist, then it is not raining. Can we infer the following from them? If we can, name the inference rule being used: Michael is a scientist.
We cannot infer that from the premises. Therefore the answer is no.
