Consider the following premises. For all x_13, x_13 is a police officer or x_13 will not listen to a song. For all x_13, x_13 will play squash if and only if x_13 is a police officer. There is at least one x_13 for which if x_13 plays squash, then x_13 is listening to a song. Can we infer the following from them? For all x_13, if is not true that x_13 will play squash if and only if x_13 is a police officer.
That contradicts the premises. Therefore the answer is no.
