According to the study, the behavioural treatment group was effective in improving sleep in the elderly. Therefore, Jack who was in the behavioural treatment group could have slept better than Bill who was in the drug-and-behavioural treatment group. However, the study also found that only the behavioural treatment group maintained the improvements at the two-year follow-up. Therefore, even if both Jack and Bill were sleeping equally well at the end of treatment, only Jack maintained these improvements at the follow-up. Therefore, the best choice is C.
