原文定位：关键词：land enclosure；根据关键词定位到文中第六段的：“In the sixteenth century enclosures were usually used for creating sheep pastures, but by the eighteenth century new farming techniques made it advantageous for large landowners to seek enclosures in order to improve agricultural production.”

选项分析：

A选项：未提到数量下降，属于无中生有。

B选项：原文的逻辑是，圈地导致了小农场无法竞争，所以去城里的工厂工作，促进了工业革命，而不是工业革命导致了圈地。

C选项：原文未提到，属于无中生有。
