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 challenged.
- States the writer’s opinion - It should clearly convey the writer's perspective or stance on the topic.
- Logical - It should be structured in a way that makes sense and follows a clear line of reasoning.
The other options (avoids controversy, states only facts, includes a call to action) may not necessarily apply to an effective opening statement.
