Had the teacher previously been dealing with the structure of a sentence and wanted the answers phrased in this particular way - which gets back to just learning by rote what the teacher tells you - a Thai educational method not practised in Europe for many decades.

Really, if the teacher was a native-English speaker, I cannot see why these answers were marked down.

Bu' then I wuz learnt to speek proper in the Saaarff of Englan'.
