Consider the following premises. For all x_13, if x_13 were a carpenter, then x_13 is working. For all x_13, x_13 is a carpenter or x_13 is a nurse. For all x_13, if x_13 were a nurse, then x_13 is working. Robert is a lawyer. Can we infer the following from them? Some lawyers will work.
 From the fact that for all x_13, if x_13 were a carpenter, then x_13 is working, that for all x_13, if x_13 were a nurse, then x_13 is working, and that for all x_13, x_13 is a carpenter or x_13 is a nurse we can infer that for all x_13, x_13 will work. From the fact that Robert is a lawyer we can infer that there is at least one x_13 for which x_13 is a lawyer. Finally, from the fact that there is at least one x_13 for which x_13 is a lawyer, and that for all x_13, x_13 will work we can infer that some lawyers will work. Therefore, the answer is yes.
