参考答案：B

解析：

译文：从Dr. Alpa Patel’的研究中可以推论出________？

这是一道推论题，从题干部分的infer可以看出，相关的动词有：suggest, imply, conclude, indicate等都表示暗示、推导、总结、表明。选项往往表现为句子。

首先通过题干部分的关键信息，Dr. Alpa Patel’（不可被同义替换掉的人名、职位名称）找到相关的段落（extensive reading）然后通过结合选项当中的关键词（名词、动词、形容词、副词等）进行筛选，由于是推论题，往往没有直接的信息，会有同义替换（paraphrasing）

Dr. Alpa Patel, a senior epidemiologist at the American Cancer Society in Atlanta, Georgia, who led the study, said:”Given that more than 60% of women report some daily walking, promoting walking as a healthy leisure-time activity could be an effective strategy for increasing physical activity amongst post-menopausal women. We were pleased to find that without any other recreational activity, just walking one hour a day was associated with a lower risk of breast cancer in these women.””More strenuous（紧张的）and longer activities lowered the risk even more.”

简便的办法是找到本段的重复词语“walking”显然该研究围绕“walking”的问题展开，该段的中心意思是：散步时健康的休闲方式，可以大大降低妇女乳腺癌的可能性。因此B. daily walking could cut the chance of breast cancer最为符合该段的中心意思（paraphrasing: from specific examples to category）
