Translation:On the fourteenth day, we only ate the strange pears.
This has to be one of the most bizarre sentences I have ever seen on Duolingo, and I have seen quite a few. I stared at the screen for several minutes before submitting my answer wondering if I had missed something that would serve to make it less surreal in such an oddly-specific way...
I'm sorry if the question seems ridiculous. But I understand from English version, that those people ate normal food for thirteen days and only on the last fourteenth day they had to eat pears. The Chech version shows us, that the poor people ate weird pears every day for two weeks running. Am I the only one seeing this dissonance?
