I answered
A sky with no stars at night

I have choose answer as A SKY WITH NO STARTS AT NIGHT because there are still stars will be available at morning time but they will be hidden but as far as we all will be in a sleep at home in night so I do not think it is as much as necessary to live a sky with no stars at night but a Sky with no clouds in morning just imagine how its looks embarrassing and we all people wakes up in morning and go to our job at morning time then it is necessary they beautiful sky should have clouds but it is not as much necessary as at night about starts.
