  1. State, with reasons, which of the four Local Authorities is most likely to be a rural area with many hills.
  2. Explain why pie charts are more suitable for answering part (a) than bar charts showing the same data.
  3. Two of the Local Authorities represent urban areas.
    1. State with a reason which two Local Authorities are likely to be urban.
    2. One urban Local Authority introduced a Park-and-Ride service in 2006. Users of this service drive to the edge of the urban area and then use buses to take them into the centre of the area. A student claims that a comparison of the corresponding pie charts for 2001 (not shown) and 2011 would enable them to identify which Local Authority this was. State with a reason whether you agree with the student.
