Which of the following would most strengthen the author’s case that universal healthcare reduces overall costs?

• A. Data showing increased wait times in primary care.
• B. A study linking vaccination rates to lower emergency visits.
• C. A comparison with countries that have better outcomes with private systems.
• D. Anecdotes from patients about cost savings.

Answer: (D)

Focusing on the type of evidence that makes a financial claim credible in a real-world sense. Anecdotes from patients about cost savings matter because they translate abstract numbers into concrete, relatable experiences. When readers hear a story about a family paying less out-of-pocket or avoiding expensive emergency visits under universal healthcare, the idea becomes tangible and personally credible. That tangible impact helps persuade by showing how the policy affects people day to day, not just how much money might be saved in aggregate.

The other options don’t strengthen the case as directly. Data about longer wait times highlights a potential downside rather than cost savings. A study linking vaccination rates to fewer emergency visits shows a beneficial health outcome and a cost relationship, but it doesn’t directly demonstrate overall cost reduction under universal coverage. A comparison with private systems offers international context but can be confounded by different structures and policies, making it a weaker direct support for the specific cost-reduction claim.
