Exercise 3: sample answer

I would look for a dated source that existed at the time, such as an official report, a timetable or a named eyewitness account, which would make it a record. If I only find retellings with no source, or details that change between versions, I would treat it as a legend until a primary source supports it. If it quotes a figure, I would check whether it is an exact count or an estimate, which makes it a round number (check with a museum or specialist history).
