问题 What is the passage mainly about? [br] Who are most likely to be overweight according to Katherine Flegal’s study?

选项 A、Heavy smokers.
B、Passive smokers.
C、Those who never smoked.
D、Those who quit smoking.

答案 D

解析 根据题干中的人名Katherine Flegal定位至原文第三个小标题下第二段,答案出现在该段最后一句话中对三组人群的对比:戒烟者、从未吸烟者和吸烟者的肥胖率分别为50%、37%和28%。因此答案应该选D项“戒烟者”。
