题目分析：
略。
选项分析：
A选项：Correct. 本选项在语法和逻辑上均是正确的。
B选项：本选项具有“主谓一致”的错误。整个句子的主语是一个单数名词——research，所以其谓语动词也应该用单数以保证体态一致，应该用has revealed，而不是have revealed。
C选项：本选项的主要问题在于by which it is produced and understood这个定语从句。先行词process在从句中做by身后的对象，放进定语从句则有：
language is produced by process and is understood by process.
and前的部分和选项A相同，主被动之间可认为没什么区别。但and身后的部分不对。过程不能发出“理解语言”这一动作，只能让语言变得可以理解。
D选项：by which身后的定语从句错误同选项(C)。主谓一致错误同选项(B)。
E选项：it指代错误同选项(C)。主谓一致错误同选项(B)。
C。 language is produced by process and is understood by process.
and前的部分和选项A相同，主被动之间可认为没什么区别。但and身后的部分不对。过程不能发出“理解语言”这一动作，只能让语言变得可以理解。
