The three characteristics that apply to an effective opening statement are:
- Debatable - An effective opening statement should present a viewpoint that can be argued or discussed.
- States the writer’s opinion - It’s important for an opening statement to convey the writer's perspective.
- Logical - A compelling opening statement should be based on a logical foundation to support the argument.
The other options, such as including a call to action, stating only facts, and avoiding controversy, do not align with the qualities of a strong opening statement in an argumentative context.
