Consider the following premises. There is at least one x_13 for which x_13 will climb a mountain or x_13 is a mechanic. For all x_13, x_13 will not climb a mountain. For all x_13, if x_13 were excited, then x_13 is not a sailor. For all x_13, if x_13 were a mechanic, then x_13 is a sailor. Can we infer the following from them? For all x_13, x_13 is excited.
 From the fact that there is at least one x_13 for which x_13 will climb a mountain or x_13 is a mechanic, and that for all x_13, x_13 will not climb a mountain we can infer that there is at least one x_13 for which x_13 is a mechanic. From the fact that for all x_13, if x_13 were a mechanic, then x_13 is a sailor, and that there is at least one x_13 for which x_13 is a mechanic we can infer that there is at least one x_13 for which x_13 is a sailor. Finally, from the fact that for all x_13, if x_13 were excited, then x_13 is not a sailor, and that there is at least one x_13 for which x_13 is a sailor we can infer that there is at least one x_13 for which x_13 is not excited, which contradicts that For all x_13, x_13 is excited. Therefore, the answer is no.
