"I do not like a lemon."
Translation:मुझे नींबू नहीं पसंद है।
It might be REALLY cool for Duolingo to allow us to click on something which opens to tell us what ALL the answers for that exercise could be.
The 'a' in this translation is kind of adorable, but a bit weird. It gives the impression that there's one specific lemon in the fruit bowl against which one holds a grudge (and the others are all dandy).
