"Lemons and bananas are fruit."
Translation:Les citrons et les bananes sont des fruits.
I had «Les citrons et les bananes ...», and then I looked at DuoLingo's suggestion, which had «Des citrons ...». I was a sucker and believed DL would be right, and changed my correct response. I should know better than to trust DL by now. What incentive could they possibly have for trying to mislead the student? :-(
