Consider the following premises. For all x_9, x_9 will read a book if and only if x_9 will cook. There is at least one x_9 for which if x_9 plays squash, then x_9 is reading a book. For all x_9, if x_9 reads a book, then x_9 is playing squash. For all x_9, x_9 will not play squash. Can we infer the following from them? If we can, name the inference rule being used: There is at least one x_9 for which if x_9 plays squash, then x_9 is reading a book.
That is one of the premises. Therefore, the answer is yes.
