Final answer:
The author's purpose refers to the reason why an author writes a text, not to be confused with a thesis statement, which is a claim made to support the author's argument or main purpose in persuasive writing.
Step-by-step explanation:
The phrase author's purpose describes B. the reason an author writes a text. When discussing the author's purpose, it's important to understand that it encompasses the motivations and reasons behind their creation of a particular work, whether it be to persuade, inform, entertain, or express themselves. This should not be confused with a thesis statement, which is a part of persuasive writing where the author's argument or main claim is stated. The thesis statement, often found at the end of an introduction or the start of a conclusion, supports the author's purpose by laying out the central argument that will be expanded upon throughout the text.
In argumentative writing, an author's thesis forms the backbone of their work, providing the claim or position that they are attempting to prove with supporting evidence. This claim is clearly stated in the thesis statement and is expertly supported with credible researched evidence throughout the text. Each paragraph typically contains a topic sentence that suggests the subject of discussion and transitions from the previous paragraphs. This is followed by a claim that relates to the overall thesis, evidence supporting the claim, and an analysis explaining how the evidence relates to the argument.
