Consider the following premises. For all x_11, x_11 is bored or x_11 will write a letter. There is at least one x_11 for which x_11 will drive a car. For all x_11, if x_11 drives a car, then x_11 is a lawyer. For all x_11, x_11 is not bored. Can we infer the following from them? There is at least one x_11 for which x_11 will write a letter and x_11 is a lawyer.
 From the fact that for all x_11, x_11 is bored or x_11 will write a letter, and that for all x_11, x_11 is not bored we can infer that for all x_11, x_11 will write a letter. From the fact that for all x_11, if x_11 drives a car, then x_11 is a lawyer, and that there is at least one x_11 for which x_11 will drive a car we can infer that there is at least one x_11 for which x_11 is a lawyer. Finally, from the fact that for all x_11, x_11 will write a letter, and that there is at least one x_11 for which x_11 is a lawyer we can infer that there is at least one x_11 for which x_11 will write a letter and x_11 is a lawyer. Therefore, the answer is yes.
