3道AI来路不明???

跪求各位帮忙
            XDJM帮帮忙…….3道AI来路不明???

我找了GMAT官方版本加上今年GMAT官方更新的版本

以下这3道AWA来路不明???

AWA JJ 里有一道题:the primary function of act is to challenge the society, not to entertain it.12月后好像出现了好几次.

The best teachers should expect students to challenge the popular ideas, rather than accept those ideas.
            

People have the duty to disobey the laws they regard unjust.
            

上面那题我只找到类似的是The primary responsibility of citizens is to obey their nation’s civil and criminal laws
            

这个版好像很冷清…….-.-!!!!!

再次跪求各位xdjm们帮忙…….
