A tech analyst compiled smartphone battery life (hours of video playback) for four flagship phones released in 2023: Phone W, 12.0 hours; Phone X, 14.2 hours; Phone Y, 16.5 hours; Phone Z, 18.8 hours. The analyst argued that battery life now varies dramatically across flagships, contradicting the industry's claim of "near-parity" among premium phones. The data point most uniquely supporting the analyst's argument is ______
Which choice most logically completes the text using the data above?
- Acheck_circle
the 6.8-hour gap (more than 50% range) between the lowest and highest performers.
- B
Phone W's 12.0 hours.
- C
the average battery life of about 15.4 hours.
- D
Phone Z's 18.8 hours.
Explanation
The claim is dramatic variation among flagships. Choice C quantifies the spread (6.8 hours, more than 50% range), the strongest evidence against "near-parity." Single values can't establish variation.
