Consider the following premises. For all x_12, if x_12 plays a game, then x_12 is a mechanic. For all x_12, if x_12 were curious, then x_12 is playing a game. For all x_12, if x_12 plays a game, then x_12 is curious. There is at least one x_12 for which if x_12 were a mechanic, then x_12 is playing a game. Can we infer the following from them? There is at least one x_12 for which if x_12 were curious, then x_12 is a mechanic.
 From the fact that for all x_12, if x_12 plays a game, then x_12 is curious, and that for all x_12, if x_12 were curious, then x_12 is playing a game we can infer that for all x_12, x_12 will play a game if and only if x_12 is curious. From the fact that for all x_12, if x_12 plays a game, then x_12 is a mechanic, and that there is at least one x_12 for which if x_12 were a mechanic, then x_12 is playing a game we can infer that there is at least one x_12 for which x_12 will play a game if and only if x_12 is a mechanic. From the fact that there is at least one x_12 for which x_12 will play a game if and only if x_12 is a mechanic we can infer that there is at least one x_12 for which if x_12 plays a game, then x_12 is a mechanic. From the fact that for all x_12, x_12 will play a game if and only if x_12 is curious we can infer that for all x_12, if x_12 were curious, then x_12 is playing a game. Finally, from the fact that for all x_12, if x_12 were curious, then x_12 is playing a game, and that there is at least one x_12 for which if x_12 plays a game, then x_12 is a mechanic we can infer that there is at least one x_12 for which if x_12 were curious, then x_12 is a mechanic. Therefore, the answer is yes.
