The author’s argument would be most strengthened by which type of evidence?

• A. Anecdotes only
• B. Quantitative data showing outcomes
• C. Opinion polls
• D. Editorial cartoons

Answer: (B)

When a claim concerns impact or effectiveness, grounding it in numbers that show actual results provides solid, objective support. Quantitative data showing outcomes offer concrete measurements of change, allowing you to see not just that something happened but how big the effect was and whether it’s consistent across contexts. This kind of evidence moves beyond individual stories or opinions by presenting verifiable, generalizable information. Anecdotes illustrate a single instance but can mislead about broader patterns. Opinion polls reveal what people think, not what outcomes occur. Editorial cartoons express a viewpoint rather than empirical results. So, presenting outcomes as data gives the strongest argumentative footing.
