For essay 2, you will be describing something in detail. Start by choosing a subject. Make sure it's something that you have spent a lot of time with and can discuss completely from your own experience. It should be something relatively specific. For example, trying to describe a whole country or even a whole city wouldn't work. Instead, describing the street you grew up on or your childhood home would be much better. Whatever you wrote about for 4.5 or 4.6 could work as well.
