麻烦看下这句话中的that从句是个什么从句?

high quality nursery schools could be established that would support families more in terms of raising the next generationthat would support families more in terms of raising the next generation就是定语从句。先行词是high quality nursery schools这种定语从句叫做分隔式定语从句,也就是先行词与从句分隔开。（主要是为了句子平衡或不产生歧义）如：The film brought the hours back to me when I was taken good care of in that far-away village．请参考：
