Consider the following premises. David is an artist. Charles is not listening to a song. For all x_3, x_3 will listen to a song or x_3 is curious. Can we infer the following from them? Charles is not curious.
 From the fact that for all x_3, x_3 will listen to a song or x_3 is curious we can infer that Charles is listening to a song or Charles is curious. Finally, from the fact that Charles is listening to a song or Charles is curious, and that Charles is not listening to a song we can infer that Charles is curious, which contradicts that Charles is not curious. Therefore, the answer is no.
