I just took the test it's A. Alfred, Lord Tennyson. He wrote it
It is a Christian allegory.
The answer is C. tear down the stone wall and get to know his neighbor better
The narrator seems to question why they need a wall but his neighbor doesn't feel the same and says the famous line "good fences make good neighbors"
Using short sentences makes the author sound rude. using run-on sentences makes the author seem super talkative. I suggest use medium length sentences to set the tone.
