A 2023 review tested four wireless routers' download speeds (Mbps) at varying distances: at 5 ft, Router I, 750; II, 720; III, 740; IV, 730. At 30 ft, I, 380; II, 90; III, 410; IV, 250. Reviewers argued that close-range performance is a misleading guide to mid-range performance. The strongest support is ______
Which choice most logically completes the text using the data above?
- A
the average across all routers.
- B
Router II's 5 ft speed of 720.
- C
Router I's 5 ft speed of 750.
- Dcheck_circle
the rank reversal at 30 ft: Router II had the second-fastest 5 ft speed but by far the slowest 30 ft speed (90 Mbps); Router III performed similarly at both distances.
Explanation
"Close-range performance misleads about mid-range" requires showing rank reversal between the two distances. Choice B captures Router II's dramatic drop, supporting the claim.
