Out of the bear, elephant, badger and hamster, the one that is least like the others is the elephant. The elephant is not furry and has no hair like the other animals listed. Elephants also have a trunk and not a nose. The elephant also doesn't have claws like the other animals. All of the animals listed are mammals since they give live birth to their young.
I believe that the best answer for this question is an allusion. An allusion is a literary device where a writer refers to some other work of literature in their own work of literature in order to make some point or add emphasis. Here, T.S. Eliot is referring to Hamlet by Shakespeare. The speaker is asserting that he is not indecisive, as Hamlet is. Rather, he is like Polonius, a servant of the king in Hamlet. Polonius is a very cautious character but is overall fairly useless. I hope this helps.
