Violence in the stands at soccer matches has gotten so pronunced in several European countries that some stadiums have adopted new rules that aim (to identify fans of visiting teams and that seat them ) in a separate area.
答案B to identigy fans  of visiting teams and seat them
我想问D错在哪里?
D at identifying fans of visiting teams so as to seat them
aim at doing 也应该是可以的呀,b是把identify  和seat作为rules的两个aim,可是d 把seat 作identifying 的目的为什么不可以?
请指教.谢谢!

aim at doing 是可以, 如果SO AS TO表目的,那摸它 的逻辑主语是什莫呢?

同意gigi。
so as to 跟简单的系表结构，而且与主语不能离太远。
因此，上面的seat的主语就模糊了。
