Which of the following should not appear in a thesis statement for a problem and solution essay?

A possible solution or solutions
Specific research and facts from sources
The problem
Who or what is affected

The correct answer is "Specific research and facts from sources."

While specific research and facts from sources are essential for supporting the thesis statement in a problem and solution essay, they should not be included in the actual thesis statement itself. The thesis statement should focus on presenting the main problem and proposed solution(s), as well as identifying who or what is affected by the problem. The inclusion of specific research and facts from sources is better suited for the body paragraphs of the essay, where they can be properly cited and discussed in detail.

In a thesis statement for a problem and solution essay, the problem, a possible solution or solutions, and who or what is affected should all be included. Therefore, the option that should not appear in a thesis statement is "Specific research and facts from sources." While research and facts are important in developing the body of the essay, the thesis statement should focus on summarizing the problem, proposing a solution, and identifying the affected individuals or entities.

In a thesis statement for a problem and solution essay, all of the following elements should generally appear:

1. The problem: The thesis statement should clearly state the problem or issue that will be addressed in the essay. This sets the context for the discussion of the problem and its potential solutions.

2. A possible solution or solutions: The thesis statement should include, at least implicitly, the proposed solution(s) to the problem. This indicates the overall focus of the essay and gives the reader an idea of the direction the author will take to address the problem.

3. Specific research and facts from sources: Since a problem and solution essay aims to provide evidence-based solutions, it is important to include specific research and facts from credible sources in the thesis statement. This helps establish the essay's credibility and shows that the proposed solutions are supported by evidence.

4. Who or what is affected: It is also important to mention who or what is affected by the problem in the thesis statement. This helps to highlight the significance and impact of the problem and aligns the reader's understanding with the overall purpose of the essay.

Therefore, none of the above elements should be excluded from a thesis statement for a problem and solution essay. They all play a crucial role in articulating the problem, proposing solutions, incorporating evidence, and conveying the impact of the problem.
