Hello. You did not present the types of feature stories, which were discussed in the classroom, which makes it impossible for your question to be answered. However, I will try to help you in the best possible way.
A feature article is an article that wants to present information in a deep and very descriptive way, allowing the reader to know the subject, that the article is addressing, in the most complete way possible. This issue can be a social issue, a current issue, a celebrity, an activity, among other issues. In this case, to answer this question, you must evaluate a subject that you are interested in and are able to present relevant information about it, in an article. After that, you should assess which of the types of feature stories discussed in the classroom, your article would fit best.
