prize5-1, Exercise 3: Questions before trusting a claim

Model answer (one possible choice: the Fringe; check):

1. How was "size" measured? Number of shows, number of performances, tickets issued, performers, or audience? A claim of "biggest" needs a stated measure.
2. Who produced the figure, and for what purpose? The Fringe Society, a council report, a newspaper or a promoter each has a reason to present the numbers in a particular way.
3. Which year, and is it comparable? Registration rules, venues and counting methods change, so figures from different years may not be like for like.

An extra question: has anyone independent checked the figure, or is it repeated from a press release?
