Psychologist: In a survey, several hundred volunteers rated their own levels of self-control and their overall life satisfaction. The volunteers who rated themselves as having better self-control also reported greater satisfaction with their lives. This suggests that self-control is one factor that helps people avoid situations likely to produce dissatisfaction.

In order to assess the strength of the psychologist's argument, it would be most helpful to know whether

A. people typically rate themselves as having significantly better self-control than expert psychological assessments would rate them as having

B. people's perceptions of how satisfied they are with their lives could be affected by factors of which they are unaware

C. there is a high level of self-control that tends to reduce overall life satisfaction

D. people's ratings of their overall satisfaction with their lives tend to temporarily decrease in situations likely to produce dissatisfaction

E. feelings of dissatisfaction significantly interfere with people's ability to exercise self-control
