关于as ...as 和more than 结构的问题

applemusic

在这两个问题上我总是搞不清楚，选项出现的时候我也不知道怎么选择，
还有关于as ---as后面的省略问题。
如According to a survey of graduating medical students conducted by the Association of American Medical Colleges, minority graduates are nearly four times more likely than are other graduates in planning to practice in socioeconomically deprived areas.

minority graduates are nearly four times as likely as other graduates to plan on practicing

原来问题里的我就没有看出来有什么错误，为什么要选下面的表达方式，？
而且我觉得原来题干里的句子读起来非常的顺口，
