<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>
I believe this to be false as of the fact that a paradox would be like this "<span>If "this sentence is false" and you agree it is true then the statement would be false but that would make it true" and so on.
