Expository Essay

Assessment Tasks
Relevance is a crucial factor in any piece of work for assessment, and relevance is determined by the question actually asked and the way you have interpreted it, which should be made clear from the outset. For that reason you should begin each piece of work by giving the full wording of the question you are answering. For the essay, in your first paragraph you
should make it clear how you are planning to address the question that was set.

A critical expository exercise is a short exercise consisting of two kinds of questions. Four exposition questions (of around 150 words per question) calling for exposition of particular arguments, or an explanation of a philosopher’s position on some matter. And one critical evaluation
question (of around 200 words) calling for a critical evaluation of the
issues discussed in the expository questions. Total word length for the
critical expository exercises is 800 words. To be satisfactory, each answer
needs to be precisely focussed, and deal in detail with the relevant textual
material.

evidence)? (About 150 words.)
