求助一道逻辑题哇

When scouts look for gymnasts to join their gymnastics teams, they often base their recruiting criteria on a gymnast's work ethic instead of his or her athletic ability. After all, even the most athletic gymnasts might not have the dedication required to succeed. Such recruiting criteria can be adjusted to minimize instances in which athletically gifted gymnasts are overlooked. These adjustments, however, increase the likelihood of recruiting unmotivated gymnasts.

Which of the following conclusions is most strongly supported by the information above?

A.

If scouts base their recruiting criteria mainly on athletic ability,  they will not recruit any gymnasts who are both athletic and motivated.

B.

If the recruitment of unmotivated gymnasts is reliably prevented, some athletically gifted gymnasts will be overlooked.

C.

Basing recruiting criteria on work ethic is only appropriate when recruitment of unmotivated gymnasts is less of a problem than is overlooking athletically gifted gymnasts.

D.No criteria—based, for example, on flexibility—are less likely than those based on work ethic to result in the recruitment of unathletic gymnasts.
E.Scouts should consider the ratio of less athletic but highly motivated to athletic but less-motivated gymnasts they desire when adjusting their recruiting criteria.

题目意思：

当S招募G时，标准是职业道德>运动能力。而许多G不能成功。标准调整为最小化忽视G天赋（即注重于运动能力>职业道德）。结果，这个调整导致不明动机的G可能性增加。

条件是Such recruitingcriteria can be adjusted to minimize instances in which athletically giftedgymnasts are overlooked.双重否定为肯定，最小化被忽视，就是最大化重视，即GG增加

结果increase thelikelihood of recruiting unmotivated gymnasts，不明动机的G可能性增加，

即UG增加

逻辑链：如果GG增加，则UG增加。

B.If the recruitment of unmotivatedgymnasts is reliably prevented, some athletically gifted gymnasts will beoverlooked.

B，如果招募不明动机的G被阻止，则一些有天赋的G将被忽视。即如果UG减少，则GG减少。

所以选B

This is a must be true problem.
The correct answer must be supported by the information from the stimulus.
From a perspective of Set Theory, the stimulus tells us some athletic gymnasts are unmotivated and some unmotivated gymnasts are athletic.
In other words, these two sets are overlapped but do not inclusively include each other.

A: too extreme. it means the unmotivated set includes the athletic set wholly.
B: Correct. the word "some" represent the relationship of the two sets accurately
C: the stimulus does not tell us the relative numerous relationship of the sets. Thus, we cannot make this conclusion.
D: Information about Other criteria is not provided. Thus, this conclusion is gratuitous.
E: the ratio indicate nothing if the scout's aim is to find people both athletic and motivated.
