求助关于AND的结构题!

在OG11补充材料的那本紫色书第82题:

geologists believe that the warning signs for a major earthquake may include sudden fluctuations in local seismic activity ,tilting ,and other defrmations of the earth's crust ,changing the measured stain across a fault zone and varing the electrical properties of underground rocks .

正确答案是D)changes in the measued strain across a fault zone , and variations in .

OG解释上说只是NOUN的平行结构, 但在划线前的other 有个AND , 根据N,N,N+N的表达,OTHER 应该是最后的名词了 所以我选的是A)changing the measured strain across a fault zone and varing .做伴随状语, 虽然意思不通.

请大家帮忙解答, AND连接的名词到底是怎么排列的?先谢谢大家了

一般OG11内的题目根据题号对照可以找到老题的题号，然后根据题号在大全注释或者讨论连接中可以找到前人对此题的分析。

and结构中的大平行套小平行，

（fluctuations in local seismic activity ,tilting ,and other defrmations），changes and variations。。。
