Questions: Which of the following is the best topic sentence for a persuasive essay? A. Cancer research is a good idea. B. Space debris is becoming a hazard and needs to be addressed with aggressive action. C. There is a global warming crisis that we need to do something about.

The answer is B: Space debris is becoming a hazard and needs to be addressed with aggressive action.

Explanation:

• Option A: Cancer research is a good idea.

  • This statement is too vague and lacks a sense of urgency or a clear call to action. It does not strongly persuade the reader to take a specific stance or action.

• Option B: Space debris is becoming a hazard and needs to be addressed with aggressive action.

  • This statement is specific and highlights a clear problem (space debris) and a necessary response (aggressive action). It sets the stage for a persuasive essay by indicating both the issue and the urgency of addressing it.

• Option C: There is a global warming crisis that we need to do something about.

  • While this statement identifies a significant issue (global warming), it is somewhat broad and lacks specificity in terms of what actions need to be taken. It could be more compelling with a more focused call to action.

In summary, Option B is the best topic sentence for a persuasive essay because it clearly identifies a specific problem and suggests a strong, actionable response.
