The three characteristics that apply to an effective opening statement are:
- Logical - It should present a clear and reasoned argument.
- Includes a call to action - It effectively engages the audience and encourages them to think or act in a certain way.
- States the writer’s opinion - An effective opening often reflects the writer's viewpoint to establish a position on the topic.
The options "debatable," "states only facts," and "avoids controversy" do not typically apply, as an effective opening can indeed be debatable, may include opinions in addition to facts, and might purposely engage with controversial topics to provoke thought or discussion.
