Which of the following best explains what a strong thesis statement is?

A. A strong thesis statement consists of several sentences that explain the writers ideas.
B. A strong thesis statement provides details about the writers personal experiences and credibility.
C. A strong thesis statement clearly and explicitly states the writers purpose.
D. A strong thesis statement addresses counterparts to the writers ideas.

C. A strong thesis statement clearly and explicitly states the writer's purpose.

The correct answer is C. A strong thesis statement clearly and explicitly states the writer's purpose.

To understand why this answer is correct, it's important to know what a thesis statement is and its purpose in an essay or paper. A thesis statement is a sentence or two that summarizes the main point or argument of the essay and guides the reader through the writer's thought process. It is typically found in the introduction paragraph.

To determine the best answer, let's evaluate the other options:

A. A strong thesis statement consists of several sentences that explain the writer's ideas.
This answer is incorrect because a strong thesis statement is usually concise and focuses on the main argument or point of the essay. It is not a lengthy explanation of the writer's ideas.

B. A strong thesis statement provides details about the writer's personal experiences and credibility.
This answer is also incorrect because a strong thesis statement should be objective and focus on the central argument or purpose of the essay, rather than the writer's personal experiences or credibility.

D. A strong thesis statement addresses counterparts to the writer's ideas.
This answer is incorrect because while a strong thesis statement may acknowledge opposing viewpoints or arguments, its main purpose is to clearly state the writer's own purpose or argument, rather than addressing counterparts.

In summary, option C is the best explanation of a strong thesis statement because it accurately reflects that a strong thesis statement should clearly and explicitly state the writer's purpose.

C. A strong thesis statement clearly and explicitly states the writer's purpose.
