Hello lazyshod- which course are you doing? A level law by any chance? How unfair of them to ask a question that hasn't been covered in any lectures and in any text books.
You can just buy an answer to this essay on the internet-(http://www.lawteacher.net/AS12AQA.php) maybe even copy answers to all the questions on your course, but eventually you'd come unstuck when it comes to the exam or when you try to practise law in the real world.
