1.(With one) of the most successful African American business in history,the MR Corporation was founded in 1959 in Detroit by Berry Gordy,Jr.
A.不改动；B.It was one; C.Being one; D.One; E.As one
但c和e为什么不行?答案说c和e与MR Corporation这个名词成分不平行,这里还要考虑平行吗?
2改句子：Although long considered a vestigial organ that has no function in humans,(the appendix,some scientists believe,may have) a significant role as part of the body's immune system.
正确答案是a,就是不改动
我选的是b：改成：the appendix,which,some scientists believe,may have
答案说b的话,句子就没动词,但which,some scientists believe,不是插入语吗?所以动词是may 反而a我觉得错是因为有2个动词啊：believe和may（就算some scientists believe是插入语,which指代appendix啊,然后动词是may have）
