So I have a line from composition:
'But balloons had the disadvantage of having to go wherever the wind blew them, so that one never knew where they would come down.'
And I was asked a question:
'What was the disadvantage of flying in a balloon?'
I was instructed to answer in my own words and be only one sentence long. I wrote:
'The disadvantage of flying in a balloon was that one was forced to go in the direction where the wind blew the balloon, and thus one had no idea where he would descend.'
My professor marked me zero. Why is this wrong?
