"Do we have sugar?"
Translation:Har vi sukker?
To state a question you should to put the verb at the beginning.
Technically you can ask a question like that, but only if you're questioning someone.
A: "Vi har ikke sukker her." "Vi don't have (any) sugar here."
B: "Vi har (jo) sukker?" "We do have sugar(, don't we)?
But this word order is not accepted in the course, as it isn't the standard way of asking a question.
