1 The anthropological concept of "culture" like the concept of "set" in mathematics()主语,is(系动词) an abstract concept (表语)which makes possible immense amounts of concrete research and understanding(定语从句,修饰an abstract concept ).
2 make(谓语) sth(宾语) possible(宾语补足语) ----------这是正常的语序,作为宾语,immense amounts of concrete research and understanding字数太多太长.因此possible这个宾语补足语放到了宾语的前面,这样做的目的是为了让句子有平衡感.
