1）选C.
这是过去完成时.前面有个“It is said”,已经是过去时态.后面的完成时就要用过去完成时.
该句其实是间接引语.直接引语的话,后面就用“has been”：
It is said in the book,“ Thomas Edison (1847-1931) has been the world leading inventor for sixty years.”
至于答案A、D是直接就排除的.因为有for sixty years表示持续性的一段时间,只能用完成时.
2）选A.
这一句可以用“asked（说过）”或者“have asked（已经说过）”.
D是第三人称单数的谓语,不能选.
选D，因为他已经去世了，这是过去的事情
1、C.had been,理由that Thomas Edison (1847-1931)_____ the world leading inventor for sixty years 是宾语从句，表示的动作“过去的过去”，用过去完成时。
2、 B ask ，理由now i can't find it 表示将会发生的动作。
