"Hoe gaat het? Goed, dank je."
Translation:How are you? Fine, thanks.
I got it marked wrong too, but "How goes it" is correct, if a bit colloquial.
I wrote: "How are you going?" as opposed to "doing". I think it would be an acceptable translation.
I think that's only an Australia thing though. If you were to ask someone that in Europe, per se, they would look at you funny.
