The three characteristics that apply to an effective opening statement are:
- debatable - An effective opening statement should introduce a topic that can generate discussion or disagreement.
- logical - It should be well-structured and make sense, providing a clear foundation for the argument.
- states the writer’s opinion - An effective opening statement often includes the writer's viewpoint, making it clear where they stand on the issue.
However, the option "includes a call to action" can also be effective in certain contexts, particularly persuasive writing, but it is not always necessary for all opening statements.
