"Is he unemployed?"
I would normally use: "Чи він є безробітний?" for "Is he unemployed?" - which is more accurate and grammatical. For me, "Він - безробітний?" is the "lazy man's" way out of speaking. I never use it.
Чи він є безробітний? has a different meaning in literary Ukrainian: 'Is it he who is unemployed?' (also, it should really have «є»). Therefore, it should not be accepted.
