因为than的左边没有出现时间状语，所以右边now直接会跟左边的a great deal这个状语比较。因为左边已经不能补出时间状语了，所以在右边补出完整的主谓以避免歧义。
除此之外，时态不同也是一个点，但不是所有GMAT的题比较的时态不同都补出了主谓。这一个split算第二位吧。

第二道题的A，it要么指代half the spending,要么指代the presidential campaign,或者a greater proportion,这三个无论谁放这里逻辑都不通顺。（Ron讲过，it、they这种pronoun，指代的时候一定是包括了essential modifier的antecedent）。
除此之外，a greater proportion是名词词组，in any previous election是状语，逻辑上看他们不会比较，所以不会产生歧义。

我猜...因为这里相当于一个独立主格？ 不能有完整的主谓宾？（ it is） a greater proportion 煮鱼 than  （it was） in any previous year . 还有就是名词性从句

Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than it was in any previous election.

A. a greater proportion than it was

B. a greater proportion than

C. a greater proportion than they have been

D. which is greater than was so

E. which is greater than it has been

这道题我选错了C，把they指代了costs，后来发现应该比较的是proporotion。
关于A答案。因为以前的proportion跟1992的proportion不是同一件事，所以不能用it（专门指代前面提到的名词）指代。
B是正选。补全省略的部分是Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than（the proportion） in any previous election.


hopefully it helps.
