Could you tell me a few lines in the poem so i can help you? does it say "I" "He/She" "You" or all of those pronouns ?
Maybe you can do a mystery??
What task are you talking about, I don't see anything?

All of these could be considered an "author's purpose". An author is technically anyone who writes anything, therefore the purpose of writing is theoretically limitless. If you have to choose one of these, however, it would be "to remind".
