问题 What is the passage mainly about? [br] According to the US National Heart, Lung and Blood Institute, the reason why older mothers’ children tend to be obese remains ______ .
选项
答案 not entirely clear
解析 根据题干中的US National Heart，Lung and Blood Institute定位至第六个小标题下第二段，再根据题干其他信息the reason why older mothers’ children tend to be obese remains，准确定位至该段最后一句：why this should be so is not entirely clear，remains与is的语法功能及意思一致，因此可填入not entirely clear。
