问题 According to Dr. Nora Volkow, the use, of drugs
Paulus could accurately predict the relapsers because
选项 A、the part of their brain controlling cognitive skills is less active.
B、a four-week intensive rehabilitation program is not effective enough.
C、he has the devices sophisticated enough to scan any brain damage.
D、something innate to their brains prompt them to use drugs.
答案A
解析 原因细节题。文章第四段末尾提到Paulus可以准确预测谁会在一年内再次吸毒。其原因在于前面的解释。第四段的主要内容就是：对戒掉毒瘾一年内又重新吸毒者的大脑扫描成像研究表明他们认知技能较差，不太容易适应新的规则。他们大脑的前额脑皮层(控制理性思维的部分)活跃度较低。证明，能够准确预测的原因在于这些重新吸毒者大脑中控制认知技能的部分活跃度较差。
