光光哥哥，我有OG，我翻了一下，是这样的
B、which was conlder and wetter than usual in some regions,slowing
C、since it was colder and wetter than usually in some regions,which slowed
D、being colder and wetter than usually in some regions,slowing
E、haveing been colder and wetter than was usual in some regions and slowed

that后面是省略了it was
另外than usual是一个习惯性的说法

那是不是说这种省略只在than usual时出现呢？希望不会碰到选项同时有省略又有补出的的题。
提出的原题，这会有新理解。
making在这里是用一个新词，来修饰前半句。和那一类不能用which和不定式来指代前句的题是一类的。可见刚才的我是有点犯困。。。

很多省略已经称为一种固定用法了
lzm书上举了
than ever(before)
than usual/necessary
than estimated/thought/anticipated
as soon as possible
应该不会出现选项同时有省略又有补出的的题，如果真的有，选省略得

习惯用法指要记住就好啦
我看了一下你的原题
making在这里是指前面整个句子Florida will gain another quarter-million jobs 这件事儿。用来可以表示前面整个一段话对后面造成影响的正确答案有两种形式：
1）现在分词；2）一个新的名词用来慨括整个句子
而which引导的和不定式一定是错误的干扰选项
