Consider the following premises. For all x_7, if x_7 were a musician, then x_7 is a poet. For all x_7, x_7 is a musician and x_7 will listen to a song. Can we infer the following from them? Sarah is not a poet.
 From the fact that for all x_7, x_7 is a musician and x_7 will listen to a song we can infer that for all x_7, x_7 is a musician. Finally, from the fact that for all x_7, if x_7 were a musician, then x_7 is a poet, and that for all x_7, x_7 is a musician we can infer that for all x_7, x_7 is a poet, which contradicts that Sarah is not a poet. Therefore, the answer is no.
