Final answer:
Option B is the best choice as a replacement for sentence 25 because it effectively summarizes the main points of the essay, highlighting that uniforms suppress individual expression and fail to solve significant issues like bullying and inequality.
Step-by-step explanation:
To bring the paper to a more effective conclusion and remain cohesive with the argument that uniforms have a negative impact, one would replace sentence 25 with a statement summarizing the main points of the argument. A good conclusion should not introduce new evidence or examples, but rather should synthesize and restate the main points of the essay.
Therefore, the best choice to replace sentence 25 would be option B: "Uniforms suppress individual expression, maintain inequality, and are useless against issues like bullying and test scores." This statement encapsulates the various argument points made earlier in the paper, specifically referencing the suppression of individuality and the assertion that uniforms don't address significant issues within the school system.
