The correct answer to this open question is the following.
Describe a situation (real or fictional) where not having a focused message in your writing could lead to a problem or poor outcome.
A situation like this can be so real that indeed just happened to me the other day. I was writing something but my mind was in other parts, so I was not focused on the task at hand. In the beginning, I had the idea and how to develop it. But then it came some distractions and my mind started to wander. I finish muy writing but the other mistake was that I did not double-check it. The result: a very bad work that made no sense at all.
So hope this does not happen to you. Please, use the writing process to ensure your writing is focused and effective. The first step is the prewriting phase, then the drafting, followed by the revising, and finally, the editing.
Follow these steps and you will have good writing.
