"Would you like bread?"
Shouldn't "visne" be accepted as well? There's nothing in the English sentence to indicate whether the person is singular or plural.
Right. I was initially thinking it wanted me to guess what number the English "you" was, so I was confused that it wanted plural; but then I realized it wanted the answer in subjunctive for some reason instead of indicative, which I'm guessing is a snag due to the course still being in beta. Latin doesn't use the subjunctive to ask questions (like English sometimes does).
