   Answer:

看也不看选择AC，但不知道选择A还是C，但我觉得C对，因为capability修饰系统才对，
                    ability 是修饰人的能力,但是讨论答案是A,为什么,牛牛帮帮忙

我的想法和你一样的， 是不是答案错了？

你的意思是说,只要是人或者动物的器官都是可以用ability 的，对吗 ？

第一题：(1)最后的and多余。前面有破折号（come from antioxidants—compounds also found in beta carotene, vitamin E, and vitamin C, and），如果不看意思，inhibit the formation of plaque along the body’s blood vessels想和前面的come并列的话，必须在最后一个and前加上“－”，请注意，这种符号是成对出现的，表示解释说明，如果后面没有看见结束“－”符号，那么说明inhibit,还是属于解释说明部分的，不能和前面的主句并列。如果和前面的come并列，应该这么改：Most of the purported health benefits of tea come from antioxidants—compounds also found in beta carotene, vitamin E, and vitamin C
                        — and inhibit the formation of plaque along the body’s blood vessels.(2) compounds also found in beta carotene, vitamin E, and vitamin C,and inhibit the formation of plaque along the body’s blood vessels,如果inhibit作为compounds的谓语，那么and 也是多于的，只需这么改：Most of the purported health benefits of tea come from antioxidants—compounds also found in beta carotene, vitamin E, and vitamin C，inhibit the formation of plaque along the body’s blood vessels.

第二提：答案C相比较答案A还是有所不妥的。关键在于in dealing，一般用capability of sb/sth to do sth 或capability fo doing，后面接in dealing很少见。一般情况下，按照GWD的说法，尽量用动词的原型，除非固定搭配一定要用in doing,否则都用to do 。

第一题写的好像有点累赘，请大家见谅。
