问题 According to a new report, healthier lifestyles and public health action could help reduce about ______.
All the following factors may increase cancer rates EXCEPT. ______.

选项 A、occupational carcinogens
B、lack of access to tobacco
C、unhealthy habits
D、aging populations

答案B

解析 该题可借助常识直接判断答案。也可利用备选项中的用词作为答案线索,这样发现文章第4段。第7段分别提到了不健康的习惯,老龄化的人口,职业引起的致癌物质,吸烟等因素及其与癌症发生率的关系。所以B(缺少与烟草的接触)是答案。
