Consider the following premises. For all x_8, if x_8 were curious, then x_8 is a musician. For all x_8, x_8 will take a plane if and only if x_8 is excited. For all x_8, if x_8 were a musician, then x_8 is taking a plane. For all x_8, x_8 is not excited. Can we infer the following from them? For all x_8, x_8 is not curious.
 From the fact that for all x_8, x_8 will take a plane if and only if x_8 is excited, and that for all x_8, x_8 is not excited we can infer that for all x_8, x_8 will not take a plane. From the fact that for all x_8, if x_8 were a musician, then x_8 is taking a plane, and that for all x_8, x_8 will not take a plane we can infer that for all x_8, x_8 is not a musician. Finally, from the fact that for all x_8, if x_8 were curious, then x_8 is a musician, and that for all x_8, x_8 is not a musician we can infer that for all x_8, x_8 is not curious. Therefore, the answer is yes.
