Health researcher Dr. Michelle Garcia argues that standing desks provide significant health benefits for office workers. She claims that standing for part of the workday reduces back pain and improves cardiovascular health.
Which study result would most directly support Garcia's health claims?
Workers with standing desks who stood for 2+ hours daily reported 32% less lower back pain and showed improved blood pressure readings compared to workers at traditional desks
Standing desk sales have increased 200% in five years
Some workers find standing desks uncomfortable initially
Regular exercise is beneficial for cardiovascular health
Correct Answer: A
Choice A is the best answer. Directly measures both claimed benefits: less back pain + improved cardiovascular (blood pressure).
- Context clues: Garcia claims "less back pain" and "improved cardiovascular health."
- Evidence evaluation: 32% pain reduction + blood pressure improvement proves both.
- Verify: Comparison to traditional desks isolates standing's effect.
💡 Strategy: Multi-benefit claims need evidence for each specific benefit.
Choice B is incorrect because sales growth doesn't prove health benefits. Choice C is incorrect because initial discomfort doesn't address long-term health. Choice D is incorrect because exercise benefits don't prove standing desk benefits.
