Final answer:
A topic sentence states the paragraph's main idea and directs its content. The validity of a topic sentence can be assessed by seeing if it reflects the reasoning strategy, supports the thesis, makes a clear point, and fulfills an intended purpose. Main points in an essay should start with topic sentences that reflect the thesis statement.
Step-by-step explanation:
The topic sentence of a paragraph is the opening line that states the main idea or argument. This sentence guides the content of the paragraph and is supported by details, examples, reasons, and evidence. It functions as a kind of mini-thesis for the paragraph, setting up what will be discussed and how it relates to the broader thesis of the writing. To verify the strength and validity of your topic sentences, you can ask yourself certain questions:
- Does the topic sentence reflect the reasoning strategy in use?
- Does it support the overall thesis statement?
- Does it make a clear and sensible point?
- What is its purpose, such as providing background information or presenting a claim?
Moreover, when planning your essay, each main point should begin with a topic sentence that is a direct reflection of your thesis statement. This practice helps ensure that your paragraphs are focused and contribute to building your argument or analysis.
