Consider the following premises. If Linda were a musician, then it is windy. William is curious or Linda is a musician. For all x_14, x_14 is a bartender if and only if x_14 is curious. If William were a bartender, then it is windy. Can we infer the following from them? If we can, name the inference rule being used: It is not windy.
 From the fact that for all x_14, x_14 is a bartender if and only if x_14 is curious we can infer that for all x_14, if x_14 were curious, then x_14 is a bartender via universal biconditional elimination. From the fact that for all x_14, if x_14 were curious, then x_14 is a bartender we can infer that if William were curious, then William is a bartender via universal instantiation. From the fact that if William were curious, then William is a bartender, and that if William were a bartender, then it is windy we can infer that if William were curious, then it is windy via transitivity. Finally, from the fact that if William were curious, then it is windy, that if Linda were a musician, then it is windy, and that William is curious or Linda is a musician we can infer that it is windy via disjunction elimination, which contradicts that It is not windy. Therefore, the answer is no.
