og12中语法26题，正确句子为Emily Dickinson's letters to Susan Huntington Dickinson, which were written over a period beginning a few years before Susan's marriage to Emily's brother and ending shortly before Emily's death in 1886,outnumber her letters to anyone else.
这个不是指代前面整个句子么？？可以么？？一头雾水.....

那是说，which不能指代整个句子但是可以指代前面的的fragment？？是只能指代逗号前面的名词还是优先指代名词？？
