还是我来给你回答这题吧.
这题和你刚才问的都是一个类型的问题,这两题认真理解清楚对于
你对这两个时态的认识有很大的好处.
现在完成时,有“现在”两个字,虽然发生的时间在过去,但着眼点永远都是“现在”
文中说爱迪生作为首席发明家(leading inventor)有60年的时间.
请问?他现在还是首席发明家吗?当然不是,他老人家早在1931年就去逝了.
比较：He has studied English for ten years.（他学英语10年了）
He studied English for ten years.（他曾经学过10年英语）
第一句用现完,说明他现在还在学英语,是从十年前学到现在的.
第二句用一过,说明他曾经学过10年,从他不学英语到现在已经有很久了.

对已故人物用一般过去时。比较：
Luxun was a famous writer in China.
Moyan is a famous writer in China.

这个题参考意义不大即便选d
也不能以此类推因为考察点很模糊出类似题的可能较小
