Consider the following premises. For all x_5, x_5 will play a game. There is at least one x_5 for which x_5 will work. For all x_5, x_5 is a taxi driver. Can we infer the following from them? There is at least one x_5 for which x_5 will play a game and x_5 will work.
 From the fact that for all x_5, x_5 will play a game, and that for all x_5, x_5 is a taxi driver we can infer that for all x_5, x_5 will play a game and x_5 is a taxi driver. From the fact that for all x_5, x_5 will play a game and x_5 is a taxi driver we can infer that for all x_5, x_5 will play a game. Finally, from the fact that for all x_5, x_5 will play a game, and that there is at least one x_5 for which x_5 will work we can infer that there is at least one x_5 for which x_5 will play a game and x_5 will work. Therefore, the answer is yes.
