In the multiple choice, "vid elva" was accepted as well. I thought that rather means "at about eleven". Or does it mean the same as "klockan elva"?
Yes, vid elva is 'at about eleven'. It shouldn't appear in the multiple choice here, I'll take a look at that.
So no lunch, then.
What does klockan mean? Is it a special kind of at that only applies when talking about time?
Guess it literally is an hour. Like here it means '(at) hour eleven'
Can one use slutar instead of stänger here as well?
