Answer:
The correct answer is option B. "Raoul's practice is massed; Scarlett's is distributed".
Step-by-step explanation:
A massed practice condition is defined as a task that its performed by an individual without taking a significant amount of rest. Since Raoul is only taking 5 seconds of rest between trials, his practice is massed. On the other hand, distributed practice conditions involve resting for longer periods of time. Scarlett is resting 40 seconds between trials, which represents a longer period of time that the trial itself (30 seconds), therefore her practice is distributed.
