During the eighteenth century,widespread changes in agriculture, known as the agrarian revolution, involving the large-scale introduction of enclosed fields, of new farming techniques and crops, and the substitution of commercial for subsistence farming.
我的思路是：the large-scale introduction 和the substitution of是并列的，所以and后面不能加of，排除DE。ABC怎么判断呢？我觉得of enclosed fields和of new farming techniques and crops是并列的，那么他们中间必须加上连词and才行么？ 句子的整体意思是在18世纪这段时间，广泛的变化在农业中被认为是agrarian革命，后面介绍了革命的内容，C选项用which指代革命，后面跟着革命的内容为什么不可以？
