As a student, I want the ability to see if a question is unanswered, answered, or resolved, so that I can figure out the more important questions to look at.

Justification for ranking:
Effort:
Requires medium efforts to add status fields of questions, define status changes, and show it in UI, which includes both backend and frontend efforts.
Impact:
Allows students to quickly identify resolved and unresolved questions, and is also helpful for course staff to quickly sort questions to answer.
