<span>C. animal
Yeats, in this poem, uses an animal (swans) to represent the way time passes and changes, and the natural beauty of that cycle. He sees the swans year after year but knows that one day, even the swans will disappear from the lake.</span>
The poem has a different understanding once you take into account she committed suicide soon after. In the poem she talk of being dead in the figurative sense and hiding it with smiles of accomplishment and illusions. Instead after you see she meant she was dead inside and when she talked of her feet saying we've gone to far she means she's tired of living. And again she talks of flowe petals closing as she closes in on herself.
What Hamlet is contemplating in his most famous soliloquy (To be or not to be) is the nature of life and what he should do with it. He is thinking about whether he should end it all (kill himself) or continue living and fighting for his revenge. His father was killed by his own brother and he wants to avenge the king's death but he is unsure how to do it.
He is torn between these two decisions, leading him to be stuck and ultimately do nothing for a while because he is indecisive. On one hand, he can go after Claudius who murderer his father, but on the other hand, he understands that that is meaningless and it won't bring him anything. However, in the end, he finally makes a decision - to go through with his plan.
I’m pretty sure the answer is balding hair.
