In defining "diction" as the choice of words employed,
Orwell might be making some distinct and deliberate choices in this sentence.  The first
deliberate word choice would have to be the linking of "studies" and pigs together. 
Indeed, Orwell depicts the pigs to be keen and studious about the prerequisites to
achieve power and how to keep it.  For example, when Old Major speaks, the Pigs are
gathered round him, paying close attention to what he says.  Clover might have been
concerned with the lost ducklings and have been in the back, but the pigs were in the
forefront, studying and analyzing what Old Major says and how he says it.  Another
deliberate example of diction would be in "succeeded in reducing."  I think that this is
powerfully effective because it helps to reflect how the pigs were skilled in "reducing"
opposition towards them.  Examine Napoleon's effective means in this realm in Chapter 7,
when he eliminates threats to his forced confessions and purges.  I think that Orwell's
employment of diction allows him to accomplish through word choice what he desire to
evoke from a thematic point of view.
