Question 14 is based on the passage you have just heard.

14. What does the speaker say about Alzheimer’s disease?

解析：B。本题目为细节题。问题为：关于阿尔茨海默病，作者说了什么？原文所在句：But by 2014, the death rate from Alzheimer’s disease for this age group had more than doubled—increasing from 3.8 percent to 8.5 percent—making the progressive brain disease the second leading cause of death for centenarians.到2014年，阿尔茨海默病所引发百岁老人的死亡率增加了一倍，从3.8%升至8.5%，这使得进行性脑病成为了百岁老人死亡的第二大原因。选项B) It is now the second leading cause of death for centenarians（它是如今百岁老人死亡的第二大原因），与文中信息完全一致。同上题，此题目要求同学们不要盲目记录数字，而是跳过数据关注句子主要含义。
