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 fi sh and shellfi sh, 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
Diction; Parallelism
Th e sentence describes the elaborate society of the
Mochica with a series of three features, the fi rst
of which contains an example. Th e three features
must be presented in parallel structures—e.g.,
cultivating, harvesting, and exploiting. Th e use of
such to introduce the examples of crops requires
that the comparison be completed with as instead
of like.
A Th e second item in the series violates the
parallelism required for the series; like
is the incorrect word to complete the
introduction of examples.
B Correct. Th e three items in the series are in
parallel form, and such crops is correctly
followed by as.
C And basing it on … must come before the
main verb in order to make this version a
complete sentence.
D Th e items in the description of the society
are not in parallel form.
E Like is the wrong word to introduce the
examples; based it on their cultivating such
crops … is awkward and wordy; they based is
parallel to they exploited, but for this sentence
to work, and would have to be inserted
before their harvest of fi sh.
Th e correct answer is B.

题目解释中提到了正确parallel structures 应该是cultivating, harvesting and exploiting.
但是选项B中却使用cultivation, harvesting 和exploitation。为什么前后矛盾还正确阿

这道题当初也差点被这个解释搞懵来着~~
解释中讲parallel structures时，只是把cultivating, harvesting and exploiting当作一个example来说的（可以看到e.g.的字眼），这时三个动词都加ing变成gerund，这是一种平行结构。同样，其它类型的平行结构也是可以的，比如三个动词都变成名词性（如选项B中的）。。不知这样说lz是否能清楚些了呢呵呵。。

个人从这道题中得到的总结是，不要看到表面的ing形式就认为是平行，还需要仔细辨别它们的功能（如动词性质还是名词性质），有的动词有tion形式的名词，有的动词没有名词形式，某些时候只能用ing形式前面加定冠词the表达名词涵义。
