A．It helps people know the benefits of being fit and healthy.
B．It encourages more people to become competitors.
C．It leads old people to start taking exercise right now.
D．It gives people a reason to take good care of themselves.
参考答案A
解析:How does the assessment of fitness age benefit people, according to Peeke?
【解题思路】四项均以it开头，描述的都是一种积极正面的结果，本题考查的内容应该是某种情况带来的积极影响。
【解析】讲话中引用皮克的话说： “这种对健康年龄的评估实际上是非常有效的，它能帮我们了解保持健康的益处。”因此选项A正确。其他三项虽然也是对健康年龄进行评估所带来的积极影响，但都不是皮克的观点，因此都应排除。
