Question

The plot below shows the relationship between the mortality risk of cardiovascular disease and the number of steps a person walks per day. Based on the data, which one of the following options is true?

Correct answer (C) For any 5000 increment in steps/day the largest risk reduction occurs on going from 0 to 5000. Solution The graph represents a convex decreasing function. The 'risk reduction' for a specific interval of steps is the change in the y-value (Mortality Risk). 1. From 0 to 5000 steps, the risk drops significantly from 1.0 to approximately 0.4 (a reduction of 0.6). 2. In subsequent 5000-step intervals (5000-10000, 10000-15000, etc.), the curve flattens, meaning the vertical drop (risk reduction) becomes smaller and smaller. 3. Therefore, the largest risk reduction for any 5000-step increment occurs in the first interval, from 0 to 5000. Turn this into a strength.
