【求助】刘振民语法改错精解E9-25

好心情

各位XDJM这道题是刘振民语法改错精解第170页的E9-25。正确答案是B，我选的C，可我始终不太明白为什么答案说“C中补出was是多余的”，望高人指点，感激不尽！！！
In his eagerness to find a city worthy of Priam, the German archaeologist Schliemann cut through Troy and uncovered a civilization a thousand years older as was the city Homer’s heroes knew.



A older as was the city Homer’s heroes knew

B more ancient than the city known to Homer’s heroes

C older than was the city known to Homer’s heroes

D more ancient of a city than Homer’s heroes knew

E older of a city than was the one known to Homer’s heroes

比较对象：civilization 和 the city, 两个宾语间的比较，加was 干嘛 ＝ ＝
