Consider the following premises. For all x_9, x_9 is a musician. If Patricia sleeps, then Linda is playing tennis. If James were a writer, then Patricia is sleeping. If James were a musician, then Linda is playing tennis. Can we infer the following from them? Linda is not playing tennis.
 From the fact that for all x_9, x_9 is a musician we can infer that for all x_9, x_9 is a musician or x_9 is a writer. From the fact that for all x_9, x_9 is a musician or x_9 is a writer we can infer that James is a musician or James is a writer. From the fact that if James were a writer, then Patricia is sleeping, and that if Patricia sleeps, then Linda is playing tennis we can infer that if James were a writer, then Linda is playing tennis. Finally, from the fact that if James were a musician, then Linda is playing tennis, that if James were a writer, then Linda is playing tennis, and that James is a musician or James is a writer we can infer that Linda is playing tennis, which contradicts that Linda is not playing tennis. Therefore, the answer is no.
