Consider the following premises. There is at least one x_12 for which x_12 will take a plane and x_12 is happy. For all x_12, x_12 is excited and x_12 is a scientist. Can we infer the following from them? For all x_12, either x_12 will take a plane or x_12 is excited are not true.
That contradicts the premises. Therefore the answer is no.
