"Are these skirts or pants?"
Translation:Ezek szoknyák vagy nadrágok?
Your confusion must be coming from "these skirts". But those two words do not belong together here. Rather, there is an implied "things":
"Are these (things) skirts or pants?"
The same thing is happening in the Hungarian sentence:
"Ezek (a dolgok) szoknyák vagy nadrágok?"
See, there is your missing article, omitted.
