这道题og上 没说by不可以 那就证明 by 和 with都说正确用法,要错就错在CDE搞乱了overcompensating和growing的逻辑关系。
本来题中想说通过animal compensating和 growing an extra两种方式来replace lost 的arm但是CDE没有体现出这是两种方式 。
the vital error in choice C is parallel, AND connects two action OVERCOMPENSATING and GROWING, so they should in same structure. Therefore, there are only choice A and C.
