This task is intended to assess your knowledge of conventional microeconomic principles (part of LO1). The word count is deliberately tight in order to force you to prioritise the most important arguments/explanations in your answers. Providing clear and concise explanations of the most important aspects will lead to good marks. Your answers should be written in an academic style.
