Exercise 3: sample answer

A claim such as "the new line will cut the journey to X minutes" is a forecast, so I would treat it as a round number and look for the assumptions behind it. A claim that it is "the first" or "the fastest" is a record only if an independent source confirms it and defines the terms. A tidy story about one person or one decision is probably legend. I would check the operator's own figures, an independent report and the date of the claim.
