Technology analyst Dr. David Park argues that free basic-tier apps generate more revenue than paid apps through advertising and in-app purchases. He suggests that the lower barrier to downloads creates a larger user base that can be monetized over time.
Which data would most effectively support Park's business model claim?
Many successful apps are available for free
Users download more free apps than paid apps
App developers work long hours
Free-tier apps earned an average of 2.99 earned only the initial purchase price, giving free apps 17% more lifetime revenue
Correct Answer: D
Choice D is the best answer. Direct revenue comparison proves free model earns more than paid model.
- Context clues: Park claims free apps "generate more revenue."
- Evidence evaluation: 2.99 lifetime revenue proves the claim with 17% advantage.
- Verify: Per-user calculation accounts for different user base sizes.
💡 Strategy: Revenue claims need per-unit comparisons, not just total earnings.
Choice A is incorrect because examples don't prove which model earns more. Choice B is incorrect because download numbers don't show revenue comparison. Choice C is incorrect because work hours don't address revenue models.
