ESSAYBID ANSWER

ANS: B
Although many factors have led to obesity in American society—including cultural pressure, increased portion sizes in restaurants (portion distortion), offers of more food at a reduced price (“super-size”), and a perceived lack of time to cook nutritious inexpensive foods—the primary cause remains the consumption of more calories than needed for physical activity. With computers and television as recreational choices, Americans are as a group sedentary rather than physically active.
