Thank you, dear Reed, for the answer.
Will you please help me with one more question. Which word is the best in the context (maybe, all of them are OK):
"the aim is to define/determine/identify and assess the actions of the Bush administration..."?
Thank you very much.
It depends on what you're trying to say...
I think determine or identify would work best with the information that I have.
Determine - This means you're trying to pin point what's going on
Identify - This means you really don't have a clue, but you're going to identify what he did.
Let me know if I can be of more assistance.
