Consider the following premises. For all x_19, if x_19 were an electrician, then x_19 is curious. For all x_19, x_19 is curious if and only if x_19 will cook. For all x_19, x_19 will cook or x_19 is an electrician. There is at least one x_19 for which x_19 will not play tennis. For all x_19, x_19 will play tennis or x_19 is a doctor. Can we infer the following from them? There is at least one x_19 for which x_19 is curious.
 From the fact that for all x_19, x_19 is curious if and only if x_19 will cook we can infer that for all x_19, if x_19 cooks, then x_19 is curious. From the fact that for all x_19, x_19 will play tennis or x_19 is a doctor, and that there is at least one x_19 for which x_19 will not play tennis we can infer that there is at least one x_19 for which x_19 is a doctor. From the fact that for all x_19, if x_19 cooks, then x_19 is curious, that for all x_19, if x_19 were an electrician, then x_19 is curious, and that for all x_19, x_19 will cook or x_19 is an electrician we can infer that for all x_19, x_19 is curious. From the fact that for all x_19, x_19 is curious, and that there is at least one x_19 for which x_19 is a doctor we can infer that there is at least one x_19 for which x_19 is curious and x_19 is a doctor. Finally, from the fact that there is at least one x_19 for which x_19 is curious and x_19 is a doctor we can infer that there is at least one x_19 for which x_19 is curious. Therefore, the answer is yes.
