Answer: Caesar refuses to reverse Cimber’s banishment. He says that, although the world is full of reasonable men, he is the only one who stands firm, and he will stick by his sentence to prove it.
Step-by-step explanation: In the given excerpt from Act 3, Scene 1 of Julius Caesar, we can see Caesar talking about the apprehensive nature of men, but he says that he is the only one that maintains firm ("And men are flesh and blood, and apprehensive; Yet in the number I do know but one That unassailable holds on his rank"), to prove that he says that he banished Cimber and Cimber should remain banished.
