 From the fact that there is at least one x_9 for which x_9 will play squash if and only if x_9 will listen to a song, and that for all x_9, x_9 will not listen to a song we can infer that there is at least one x_9 for which x_9 will not play squash. From the fact that for all x_9, x_9 is rich or x_9 will play squash, and that for all x_9, x_9 is not rich or x_9 is bored we can infer that for all x_9, x_9 will play squash or x_9 is bored. Finally, from the fact that for all x_9, x_9 will play squash or x_9 is bored, and that there is at least one x_9 for which x_9 will not play squash we can infer that there is at least one x_9 for which x_9 is bored.
