The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Reflective, informal writing can help someone develop an informed and well-considered opinion on an issue. because used an understandable common-day language, people can better understand complicated issues in a simpler way.
If the writer knows how to approach a complicated idea and turned it into simpler terms so more people can grasp the basic ideas, then he/she is a talented writer. For that to happen, the writer has to really know the topic: context, origins, evidence, consequences, and more.
Once understood, the author will be able to explain it in a clear way so people can be aware of the issue and the way they can do something to solve it or to move people into participation.
