For context, I was writing about different activities that took place during a programme. I discussed five out of six different types of activities and then said:
'The final type of activities was organised trips '
as an introduction to paragraphs that discuss these trips.
My supervisor corrected me and suggested that it should be:
'The final type of activities were organised trips'
However, I think that the subject is 'the type' (singular) and not 'organised trips' (plural). So in my mind it should be was not were...
Am I wrong? Please help...
