I found a path:
choose the yellow (bottom right) answer for the second question and have the narrator ask "do you think you're funny?" which reliably happens if you answered the first question "alpaca", then said that you do know what a color is.
Then, answer that you do not think you're funny.
Then, the narrator asks you morality questions. after you answer them, I had the narrator tell me that he wanted to ask these questions all along but was not allowed to, and show signs of relief as he tells you that he was afraid of you just being another troll. You will then get a 4/5.
