On Wednesday I showed you a task 2 essay that I wrote with some of my students. After reading the essay again, I noticed that we hadn't fully answered all parts of the question. Paragraph 3 needed to say more about "alternative sources of funding for artists".
One thing that this shows you is that nobody is perfect! A more important lesson to learn is that you should keep checking the question as you write your essay. Make sure you cover everything that the question asks you to cover.
