Consider the following premises. For all x_3, x_3 will not make tea or x_3 will play squash. For all x_3, if x_3 plays squash, then x_3 is curious. There is at least one x_3 for which if x_3 were an office clerk, then x_3 is fast. For all x_3, x_3 will make tea or x_3 is an office clerk. For all x_3, if x_3 were fast, then x_3 is curious. Can we infer the following from them? If we can, name the inference rule being used: For all x_3, x_3 will not make tea or x_3 will play squash.
That is one of the premises. Therefore, the answer is yes.
