A new handheld device purports to determine the severity of concussions by reading the brain’s electrical signals and comparing them to a database of 15,000 scans compiled at a brain research lab. The device is intended to help doctors decide whether an athlete who has received a blow to the head during a competition should be sent back into the game.
Which of the following would it be most useful to establish in order to evaluate the effectiveness of the device for its intended purpose?
Whether the database of brain scans will regularly be updated with new scans
Whether by use of this device doctors will be able to make a sound decision about whether to allow an athlete back into the competition before it ends
Whether the device will be endorsed by a large number of medical professionals
Whether the database includes scans of non-injured athletes in the same game as the injured athlete
Whether team doctors have until now been mistaken in their assessments of whether an athlete can safely continue to play
一开始的思路是对的
B选项中表示：医生能否通过这个仪器的使用做出明智的选择，关于是否让运动员在比赛结束前返回比赛
目的：帮助医生决策能够让头部受伤的运动员重返赛场
方案：使用这个机器，检测受伤的人和数据库中的数据对比
B选项对应方案的实现方式
D选项在这方面大致类似于更好的方案？
实际上有了数据库反应一般情况，哪怕没有未受伤运动员的情况，也能够反映受伤者的指标是否符合正常
E选项大概是因为和使用仪器达成目的的这个方案关联较小
