With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.Through sensors.Through a mobile robot.It can locate people and do any task.D.Doubtful.B.Elderly people leave the nursing home.根據(jù)章第二段中的“ The Robot Activity Support System, or RAS, uses sensors （傳感器）equipped in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities”可知機(jī)器人活動支持系統(tǒng)（RAS）使用WSU智能家居中配備的傳感器（傳感器）來確定其居民在哪里，他們在做什么以及何時(shí)需要日常活動的幫助，說明傳感器起到了重大的作用，故選A。 （3）考查推理判斷。再根據(jù)最后一段中的“The next step in the research will be to test RAS39。 Andre has spent 20 years developing an advanced system to better understand why incidents like this happen.
