答案
参考答案：B
解析：
译文：根据本文，下列哪些说法是正确的？
由于题干部分没有可供定位的关键词信息，因此应通过选项当中的信息来定位。其中有三个选项的关键词都和“walking“相关，
Of the women,47% said walking was their only recreational activity.（A. Most women take walking as their only recreational activity. 不正确，不是大多数女人把散步当做唯一的休闲方式，而只有47%，）因此B. Walking was the only recreational activity for about half of the women.是最符合原文意思的。
