Consider the following premises. It is not windy. It is windy if and only if David is playing squash. It is overcast if and only if Patricia is listening to a song. For all x_23, x_23 will not listen to a song. Can we infer the following from them? It is overcast.
 From the fact that for all x_23, x_23 will not listen to a song we can infer that Patricia is not listening to a song. Finally, from the fact that it is overcast if and only if Patricia is listening to a song, and that Patricia is not listening to a song we can infer that it is not overcast, which contradicts that It is overcast. Therefore, the answer is no.
