问题 The device has a sensor that measures body temperature and changes to the heart rate called HRV.
选项 A、正确
B、错误
答案 B
解析 原文说：The device has a sensor that measures hemoglobin oxygen levels and changes to the heart rate called HRV．这里有一个术语(hemoglobin oxygen levels)可能有的同学不太熟悉，但是，文章后面提到了blood oxygen levels(血氧水平)，不是体温(body temperature)，因此，是错误的。
