Consider the following premises. If William plays a game, then Karen is driving a car. If Richard were a musician, then it is late. Elisabeth is bored or Richard is a musician. Elisabeth is not bored or William is playing a game. If Karen drives a car, then it is late. Can we infer the following from them? It is not late.
 From the fact that Elisabeth is bored or Richard is a musician, and that Elisabeth is not bored or William is playing a game we can infer that Richard is a musician or William is playing a game. From the fact that if William plays a game, then Karen is driving a car, and that if Karen drives a car, then it is late we can infer that if William plays a game, then it is late. Finally, from the fact that if Richard were a musician, then it is late, that if William plays a game, then it is late, and that Richard is a musician or William is playing a game we can infer that it is late, which contradicts that It is not late. Therefore, the answer is no.
