(A) relations between nations that illustrates
(B) relation of one nation with another that illustrates
(C) relations between nations that illustrate
(D) relation of one nation with another and illustrate
(E) relations of nations that illustrates
答案为B.答案中的that指代relation,我的问题是:that 在什么条件下可跳跃指代,如本题,为何that 不是指代lecture, nation, or episodes, 只能从意思上判断吗, 谢谢指教.
