ABSTRACT
Writing tasks frequently ask students to examine a problem and evaluate a range of solutions. This unit explains ways in which this kind of text can be organised. Currently, roads are often congested, which is expensive in terms of delays to the movement of people and freight. It is commonly suggested that building more roads, or widening existing ones, would ease the traffic jams. This remedy is criticised for being expensive and liable to lead to more road use. This may be partly true, yet the alternatives are equally problematic. Road pricing has many practical difficulties, while people are reluctant to use public transport. There is little alternative to a road-building programme except increasing road chaos. Many developing countries have found that the development of a tourism industry can bring social and environmental drawbacks. One possible solution is to target upmarket holidaymakers, in order to get the maximum profit from minimum numbers.
