单选题 Dimpy, the girl named in this passage ______.

A、 began to smoke when she was eleven
B、 became the focus of concerned policymakers because she has been smoking for quite a few years
C、 showed pictures of gross lungs of smokers to her fellow pupils
D、 forgot the shops where she usually obtained her cigarettes

【正确答案】 A

【答案解析】从文章第一段可知Dimpy现在14岁，上九年级，而她开始吸烟时是上六年级，所以可推出那时她是11岁；B项不正确，因为受到关注的是像Dimpy那样的青少年，而并非只有 Dimpy一人；C，D两项明显与原文不符。
