请教一个英文句子的语法问题
as a consequence,efforts to improve economic and social condition,which have a transportation component,as most do,are less efficient and the breadth of opportunities is more restricted.
请大虾们帮我分析下上面这个句子的语法,which 引导的那个句子在里面是充当什么成分?跟efforts的那句有啥语法关系?
答
which 引导的是定语从句,修饰efforts to improve economic and social condition这个名词词组的,而to improve economic and social condition又充当一个定语来进一步修饰effort,到底是怎样的effort.
