We took ourselves off to the museum , delightfully cool in the aircon - it 's around 35 outside . I was inspired by the olympic swimming and rushed into the refreshing river , picking my way through broken glass . Dinner was going to be at a nice hotel as a special treat but low and behold , no food . They were cleaning .
According to the above context, answer the following question.
Why was there broken glass in the swimming pool ?


None of the above choices .
