标志：Even the “radical” critiques (of this mainstream research model,) (such as the critique developed in Divided Societ y ,) attach the issue of ethnic assimilation too mechanically to factors of economic and social mobility and they are thus unable (to illuminate the cultural subordination of Puerto Ricans as a colonial minority).

译文： 甚至连（对这种主流研究模式的）“激进”批评 ，（比如在《分裂的社会》一书中的批评 ），也把 民族被同化的问题机械地与 经济和社会流动性的因素联系到一起，这样 这些批评 就无法 （把PR人作为殖民地的少数民族来说明其文化上的次等地位）。

解释： 本句实际上是由and连接的两个句子。阅读的一个难度在于，and之后省略了主语they （此处指前面的主语the “radical” critiques），而are thus unable to又与前面离得太远，使读者难以找到主语。

另外，句中的固定搭配attach A to B当中的A、B既长又抽象，理解起来较为困难。
