<span>The answer is b visionary. 
When the animals were to successful take control of the farm from the
humans everyone was jubilant from their victory.  Benjamin on the other hand, was not as
excited about it as the others.  He seems
to know that what the future may bring based on past events and how things go
about in the present.  He can already
foretell what will happen in the long run. 
Still, he keeps it all to himself knowing that the only thing that
changed was the one in charge of the farm.  He can envision the future but he sees it in a pessimistic light.</span>
