For Amy's task of using lines from the poem in her writing, the best strategy would be A. direct quote. This approach allows her to incorporate the lines from the poem exactly as they are written, preserving the original language and meaning, which can enhance her argument or analysis.
If she were to summarize or paraphrase the lines, she would lose some of the poem's specific imagery and emotional impact. In-text citation is necessary if she includes a direct quote to give proper credit to the original author but isn't a standalone strategy for using lines from the poem.
