Answer:
1. In my opinion, the correct answer is B. a sidebar containing a brief interview with a former New Orleans resident who was displaced by the storm. As opposed to a hard news article, a feature article will contain much additional information that can shed new light on the topic. A feature story is usually long and includes a lot of quotes, as a direct and authentic way to show a point, rather than telling it.
2. I believe the correct answer is C. often. Prevalent actually means widespread, frequent, common, predominant, usual. It is the antonym (the opposite meaning) to the expressions "very rarely" and "occasionally".
3. In my opinion, the right answer is C. Carmen is a volunteer at the local hospital. The word "volunteer" describes what Carmen is - therefore, it defines the subject. Predicate nominatives actually complement (complete) their subjects, revealing who or what they are.
