"Does Keoki have four pairs of glasses?"
Translation:ʻEhā makaaniani o Keoki?
They have been pretty good about accepting either "pairs of eyeglasses" or just "eyeglasses". I can't say it's not missing in a sentence or two here or there, but I always put "eyeglasses" and have not been marked wrong yet. If you get marked wrong again, check carefully to make sure there isn't some other error, but if not, make sure to use the report flag button to say, "My answer should have been accepted."
