Couldn't it be "Hva lager de"?
That would be "What are they making?"
Hvorfor 'gjør' og ikke 'gjøre'?
It is å gjøre that is an infinitive form of presens' gjør.
Does the verb "gjor" has diffrent meanings? In this sentence it is the translation for "doing" and in another previous sentence it was translated as "driving"?
Why is it de and not det?
De = They. Det = it/that...
why de not dere
De = they
dere = you (plural)
Will Hva gjør de? be correct
