Task Two is report essay, which has nothing to do with your opinion (or anyone’s opinion, for that matter). Your job is to interpret a graphic data into a written text. Unlike Task Two where you will be given questions, this task has no guideline questions. Therefore, the most important thing is to select the right angles to write about, using around 150-170 words. There are four criteria to be concerned just like Task One but the detail of assessment is different. Please see this link.
