57.      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

白勇语法说过~代词的逻辑指代顺序是：当在主从句中 代词优先指代主句中的主语核心词--》宾语核心词--》修饰语中N
但是这道题的OG解释说 C  D 选项的IT 都可以指代 ALGERIA 和 strait 
their grip on Algeria was not ever secure if they did not hold it  其实本身也是条件从句
为什么不能优先指代到主句中ALGEIA 虽然这样想这道题也作对了 但是为什么还可以指代那个strait  那个strait 可是外面一个大主句的内容·····不是可以优先么·
很confused   就是对这种很多层主从句中的代词搞混


希望NN进来指教

这题不套规则直接看为画线部份
Morocco （was） also of interest to（ the French） throughout the first half of the twentieth century because （they） assumed that

这样括起来 因该就可看清楚谁带谁了
顺便补充 the French 国名前加冠词 表人种 用多数
