although the turtle has been toothless for more than 150 million years, in some contemporary turtle species the moderately sharp and jagged edges of their horny jaws function for teeth.
A. their horny jaws function for teeth
B. its horny jaws function for teeth
C.its horny jaws function as do teeth
D the horny jaws function as teeth do
E the horny jaws function as teeth
Answer is E.
有两个地方不清楚: 1) as ...do 到底什么情况要加do? 2) the 的用法是否比its 好，its似乎这里并没有歧义。
刚看一个刚考完的NN说 他考SC主要还是看意思分辨 我觉得这道题也是 关于问题1 ：(in some contemporary turtle species) (the moderately sharp and jagged) edges of the horny jaws function as teeth 是说这个edges和teeth的function相像 如果加do 那指代哪个动作呢？ 关于问题2：its horny jaws 那就是一个龟好几个下巴了（估计是比较能吃得怪龟了......）
刚刚查字典确实function有 动词词性 那我原来就疏忽了 不好意思 看来就是动词补出的问题了 A study commissioned by the Department of Agriculture showed that if calved exercise and associate with other calves, they require less medication and gain weight more quickly than those raised in confinement.这个例子就是前面要对比两个动词，所以不补出动词 这是一种情况 不过关于这道题......我再查查
大全 171 Because young children do not organize their attention or perceptions systematically, like adults, they may notice and remember details that their elders ignore.
刚才看了几篇文章说基本上如果不出没有歧义就要补出来（要比不补出好） 关于本题the moderately sharp and jagged edges of the horny jaws function as teeth 会不会是因为moderately sharp and jagged edges 是两种不同的Functions(这里是名词 呵呵) 相当于moderately sharp function and jagged edges function(这里是动词) 如果补出do那么就不知道指代哪个function了 （写完之后觉得自己like a pervert 是不是误入歧途了 GMAC不会这么变态吧） 还是请牛人指教吧
