Translation:Who is the person who composed this song?
Your answer is a less literal translation. Look at the words used in the hawaiian sentences, and which are missing from your answer. Your answer still conveys the same meaning, but is just slightly off in terms of literal accuracy. The Duolingo lessons for Hawaiian are inconsistent in their dedication to having literal vs. figurative translations; so that being said, I would still have your answer accepted... if all the different versions of setences that convey the same meaning are inputed into the system.
