OG12 SC28的C选项看不懂

28. Building
on
civilizations that preceded them in coastal Peru, the Mochica developed their own elaborate society, based on cultivating such crops like corn and beans, the harvesting of fish and shellfish, and exploiting other wild and domestic resources.
(A) based on cultivating such crops like corn and beans , the harvesting of fi sh and shellfi sh, and exploiting
(B) based on the cultivation of such crops as corn and beans , the harvesting of fi sh and seafood , and the exploitation of
(C) and basing it on the cultivation of crops like corn and beans , harvesting fi sh and seafood , and the exploiting of
(D) and they based it on their cultivation of crops such as corn and beans , the harvest of fi sh and seafood , and exploiting
(E) and they based it on their cultivating such crops like corn and beans , their harvest of fi sh and shellfi sh , and they exploited
这道题C选项的解释是And basing it on … must come before the main verb in order to make this version a complete sentence.这句话看不懂什么意思啊，求解释！我当时做的时候是直接排除的C，这个选项中的三个因素不平行，且感觉and basing it on 稍显啰嗦，没有based on来的简洁有效，但是看了解释，偶的想法和OG的完全不一样啊，迷茫了~~

(C) and basing it on the cultivation of crops like corn and beans , harvesting fi sh and seafood , and the exploiting of

要抓句子主干。句子的主谓宾是 the Mochica developed their own elaborate society. 前头building on .... 是【V-ing短语】在句首，修饰主句主语，也就是the Mochica。而based on...是【V-ed形式】作定语，修饰前面紧邻名词society,作后置定语。但这些都只是修饰成分，并不影响主句的完整性。


而C的问题，在于用了个and。and表并列，而且需要前后的形式一致。如果后面是basing的话，就不可能和developed平行，只能和building平行。但没有这样，先一个修饰语，然后主句，再and连接另一个修饰语的。。and后面句子不完整，缺少谓语。
