Consider the following premises. For all x_10, if x_10 were excited, then x_10 is a scientist. If it is windy, then Joseph is excited. For all x_10, if x_10 were a scientist, then x_10 is excited. Can we infer the following from them? If it is windy, then Joseph is a scientist.
 From the fact that for all x_10, if x_10 were excited, then x_10 is a scientist, and that for all x_10, if x_10 were a scientist, then x_10 is excited we can infer that for all x_10, x_10 is excited if and only if x_10 is a scientist. From the fact that for all x_10, x_10 is excited if and only if x_10 is a scientist we can infer that for all x_10, if x_10 were excited, then x_10 is a scientist. From the fact that for all x_10, if x_10 were excited, then x_10 is a scientist we can infer that if Joseph were excited, then Joseph is a scientist. Finally, from the fact that if it is windy, then Joseph is excited, and that if Joseph were excited, then Joseph is a scientist we can infer that if it is windy, then Joseph is a scientist. Therefore, the answer is yes.
