问题 Bad eating habits, increased food availability, increasingly sedentary lifestyle and reduced physical activity are the first four causes of the obesity epidemic.
Black women are  ______ per cent more likely to be obese than Mexican-American women.

选项

答案30

解析 本题涉及到黑种妇女和墨西哥裔妇女的发胖概率比较,从而将题目出处定位到A Little Older...部分。该部分首段末句涉及到黑种妇女及墨西哥裔妇女和白种妇女的比较,前者30%,后者60%。但题干中却变换了一下比较项,应为60%减30%。
