Consider the following premises. James is playing squash. For all x_16, x_16 will drink water or x_16 will not play squash. If James drinks water, then it is sunny. Can we infer the following from them? If we can, name the inference rule being used: It is not sunny.
 From the fact that for all x_16, x_16 will drink water or x_16 will not play squash we can infer that for all x_16, if x_16 plays squash, then x_16 is drinking water via universal rewriting. From the fact that for all x_16, if x_16 plays squash, then x_16 is drinking water we can infer that if James plays squash, then James is drinking water via universal instantiation. From the fact that if James plays squash, then James is drinking water, and that James is playing squash we can infer that James is drinking water via modus ponens. Finally, from the fact that if James drinks water, then it is sunny, and that James is drinking water we can infer that it is sunny via modus ponens, which contradicts that It is not sunny. Therefore, the answer is no.
