Final answer:
An effective b) thesis statement should not be an announcement, but rather a declarative sentence that presents a fact, opinion, and reasoning behind an argument.
Step-by-step explanation:
A thesis statement is a concise summary of the main point or claim of an essay, research paper, or other academic document. It typically outlines the key argument or stance on a topic, providing a roadmap for the reader. A strong thesis guides the overall direction of the work, offering clarity and focus to the writer's intentions while inviting further exploration and discussion.
An effective thesis statement should not be an announcement. It should be a declarative sentence that presents a fact, your opinion, and the reasoning behind your argument. The thesis statement is usually placed at the end of the introduction and previews the organization of the paper and the recommended solutions.
