Answer:
A. to show that cleaning the room will be a huge task.
Explanation:
We do not know what poem this is referring to, but this poet uses a simile or metaphor. This is a type of figurative language and is not meant to be "taken literally." This rules out options C and D because there is not an <em>actual</em> elephant.
While B could still be an answer, the narrator could have cleaned up their room once before without it feeling like a big task. Since they chose to compare it to an elephant specifically, we can guess that the answer will be "A. to show that cleaning the room will be a huge task."
In this excerpt from The Song of Hiawatha, Henry Wadsworth Longfellow tries to share with the reader the feelings about native american indians and their beautiful traditions with the objective of recording the deeds of Hiawatha and showing the reasons why he was so imporant for his tribe.
