请教“代词指代”的问题

xiaobaibai92112

Affording strategic proximity to the Strait of Gibraltar, Morocco was also of interest to the French throughout the first half of the twentieth century because they assumed that if they did not hold it, their grip on Algeria was always insecure.
(A) if they did not hold it, their grip on Algeria was always insecure
(B) without it their grip on Algeria would never be secure
(C) their grip on Algeria was not ever secure if they did not hold it
(D) without that, they could never be secure about their grip on Algeria
(E) never would their grip on Algeria be secure if they did not hold it
答案为B，为什么CE中it就指代模糊？？怎么样的才算指代清晰，怎么样的算指代模糊？这个好糊堵。。。求大神解答！

先回答你的问题：
it一般指代前面提过的东西，把每个选项放到题干里，AB前面只提过France，但是CE前面France,Algeria都出现不知道是指哪一个。

关于做这个题的思路：
1.题干里有assume且五个选项的意思都是假设在某种情况下会发生什么，所以后半句应该是未来时态，AC一定错，D可能可以，BE留
2.分析D,D和BE的一个区别是it or that， it指代明确的同一件东西，即这个东西就是前文提到的东西；that相对模糊。比如这里的天气比那里的天气变化更多，则这句话如果要指代天气会用that而不用it，因为两地的天气不是同一个天气，D去掉
3.分析BE，E的缺点在于it指代不明，另一个E用的是倒装，带有很强的情感色彩，GMAT是商科交流语气，陈述句更加清晰且理智（官方解释倒转繁琐且让人困惑我的理解是倒装句一次性读下来应该没有一句正常的话读下来爽快），E去掉
