Consider the following premises. For all x_14, x_14 is not a soldier. John is a soldier if and only if William is drinking water. For all x_25, x_25 will take a plane and x_25 will climb a mountain. Can we infer the following from them? William is drinking water.
 From the fact that for all x_25, x_25 will take a plane and x_25 will climb a mountain we can infer that Patricia is taking a plane and Patricia is climbing a mountain. From the fact that Patricia is taking a plane and Patricia is climbing a mountain we can infer that Patricia is taking a plane. From the fact that for all x_14, x_14 is not a soldier we can infer that John is not a soldier. Finally, from the fact that John is a soldier if and only if William is drinking water, and that John is not a soldier we can infer that William is not drinking water, which contradicts that William is drinking water. Therefore, the answer is no.
