SECTIONA-19

19.   The last “wild” Indian in North America, according to anthropologist Alfred Kroeber, was the lone survivor of California’s lost Yahi tribe, which staggered out of the mountains near Lassen Peak in 1912, deep in mourning for the last of his companions, expecting to be butchered and eaten by white ranchers. A

(A) which

(B) who

(C) that

(D) the survivor having（B）

(E) having

这个从句是修饰tribe的吗？which不能用吗？

另外deep in mourning for the last of his companions, expecting to be butchered and eaten by white ranchers在这里是什么作用？

修饰survivor，所以用who（也是后面句子得逻辑主语）
