Answer: (3) Yes, it uses supporting evidence.
In "Forgetfulness", by Billy Collins, the possible theme of the poem is<em> D. Retiring, packing a bag, and floating down a river are similar to losing one's memory</em>. First, Collins writes that we first forget the author of a novel and then we completely forget of its existence at all. Lost memories are compared to someone retiring to a fishing place without phones, so we cannot reach them. There is a personification when he writes that the memory of the quadratic equation "pack its bag". He then writes about floating down the Lehte river, it is a Greek mythological river and if you floated down its waters you forgot what you knew.
