Exercise 2: sample answer

A documented claim rests on contemporary evidence such as a patent, dated press report or surviving machine: Drais's machine and its patent of around 1818 (check). An attributed claim is made long after the event, often by a family or town, and its evidence is debated: the story of a Scottish blacksmith building a pedal-driven machine in the 1830s (check). A legendary claim has no firm provenance: the drawing sometimes said to show a bicycle from the 1490s, generally regarded as not authentic (check). The categories matter because each deserves a different level of trust.
