A diagram. The last Task 1 type is writing about a diagram. It is important that you look closely at what is being presented and carefully read all of the labels attached to the diagram. In this example, there are 5 different labels. To write 150 words and get a good result, you will need to do more than just describe what is labeled. You will need to describe most of what you see. In the example, you could write about the two windows being close to each other and relatively high compared to the door.
