Translation: जूलिया खेल सकती है लेकिन पीटर सो नहीं सकता।

Why does this sentence not end with है ?

[emrys29]

You can drop the 'hai' if the sentence is negated. I don't recommend doing it though.

Let poor Peter sleep :'(

[GabrielBou109736]

I think that Duo wants us to know that Peter has the ability to not sleep, not that he is forbidden to. He CAN not sleep: वह नहीं सो सकता है। He can't sleep: वह सो नहीं सकता है। but that's a wild guess...
