Consider the following premises. Sarah is driving a car if and only if Barbara is a cashier. If James were bored, then Sarah is driving a car. For all x_15, if x_15 were a cashier, then x_15 is excited. Barbara is not excited. Can we infer the following from them? If we can, name the inference rule being used: It is snowing.
We cannot infer that from the premises. Therefore the answer is no.
