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
♠ 注意：限定条件【during a competition 比赛中】
目的：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.
这个[设备]用来帮助[医生]决定是否应将在比赛中头部受到打击的运动员送回【比赛中】。
选项B最相关：
B选项：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】
通过使用该[设备]，[医生]是否能够在【比赛结束前】就是否允许运动员重返赛场做出明智的决定
回答yes or no 分别指出设备有效和无效
（评价有效性：注意限定的有效条件：时间、类型、地点……）
OG类似题目：评价【教室内】上电脑课纠正姿势减少手腕受伤
正确选项：whether【教室外】
看经过device检测concussion的运动员是否会出现严重的不适：是的话，device不准，好的决定，游泳
- B correct： 运用设备做sound decision about 运动员重返的比赛的状态（范围明确）
对于C 不要自己多想 intend 一起的目标不是普及使用 而是可否正是证实他的功效它的功效
A 和intend purpose 无关 读题读题读题
B. Correct. If the answer is yes, then the device is effective for its intended purpose. If the answer is no, then the device is not effective for its intended purpose: to help doctors make sound decisions about whether athletes who have suffered a head blow can safely resume play during a game.
