"the parents of the child"
Translation:nā mākua o ke keiki
I answered with "nā mākua o ke keiki," but got the admonition to pay attention to the accents. I believe I answered correctly (with the macron in "mākua"). I'm sure the admonition was not warranted.
Aloha e Stephanos! Mahalo for posting this to the forums. There was an error on our side, where "makua" was accidentally used in place of "mākua". It has now been corrected, and should give you a fully correct answer once the Duolingo system updates.
