Sports analysts studied four professional tennis players' first-serve speeds (in mph) and first-serve accuracy (% in)—Player W, 122 mph, 71% in; Player X, 130 mph, 64% in; Player Y, 138 mph, 58% in; Player Z, 144 mph, 51% in. The analysts argued that as serve speed increases, accuracy declines—a classic speed-accuracy tradeoff. The data most directly supporting the tradeoff claim is ______
Which choice most logically completes the text using the data above?
- A
Player W's accuracy of 71%.
- Bcheck_circle
the inverse pattern: speed rises from 122 to 144 mph as accuracy drops from 71% to 51%.
- C
Player Z's serve speed of 144 mph.
- D
the average speed across all four players.
Explanation
A "tradeoff" requires evidence of inverse movement between two variables. Choice C captures this monotonic inverse relationship across all four players, the strongest data support for the tradeoff claim.
