[EX Q]: Article: Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet. In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry . Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports. Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight. If you have been sedentary and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
Question: What is said about the average American in the passage?
Options: (A) They tend to hate "light" beer and low-calorie bread. (B) They usually ignore the effect of exercise on losing weight. (C) Most of them were combining exercise with their diet. (D) They know the actors that play a positive role in keeping down body weight.

With the saddest eyes I have ever seen, she continued. She said she had two babies, but she could no longer support two of them. She was taking her son to a family in New Hampshire. As she stood in front of me, crying, I could see the hopelessness on her face. I went away and got some diapers from the other mothers, and gave her a sweater of mine. After the woman and her son had changed their clothes, I sat with her, holding her hand, trying to provide some support and comfort. I could feel her pain and her love for her baby son. During that time, I kept thinking of my children who were waiting for me in New York. Once we landed, I walked with them to their next flight, which would take them to their final destination. The woman thanked me a lot, and I replied, "Thank you, too." At this moment, I couldn't wait to return home to see my children.
