The government predicts that, for consumers and businesses that make a large number of long-distance calls, the Federal Communications Commission's recent telephone rate cuts will greatly reduce costs, though some consumer groups disagree with the government's estimates, suggesting they are too optimistic.
The government predicts that, for consumers and businesses that make a large number of long-distance calls, the Federal Communications Commission's recent telephone rate cuts will greatly reduce costs
The government predicts that costs will be greatly reduced for consumers and businesses that make a large number of long-distance calls by the Federal Communications Commission's recent telephone rate cuts

choice c, the prediction is ...不如predicts that
choice d,e: for consumers and businesses 作为状语修饰主句的谓语动词predicts
Choice A, on the other hand, correctly captures the intended meaning of the sentence: The government is making a general prediction (it's not a prediction aimed at anybody in particular), about the rate cuts that will be experienced by certain individuals.
the passive voice is indeed a problem, because it's unnecessary. (remember that the passive voice should only be employed when there's a fairly compelling reason to use it.) in choice b especially, there's also an unacceptably long distance between the passive-voice action (will be greatly reduced) and the agent of that action (by the ...).
one thing you should definitely notice in choice c is the wordiness of 'the government's prediction is'. constructions like that, which can easily be replaced by more compact forms ('the government predicts') with no change in meaning, are ALWAYS wrong. (also, you need the word 'that' after 'is'.)
the prepositional phrase at the beginning of choice e is an example of a dangling modifier: one isn't quite sure exactly what it's supposed to modify. according to the strict rules followed by the gmat, this phrase should technically modify the action directly following the comma (the government predicts), which doesn't make sense: the government is not making predictions for the benefit of consumers and businesses (rather, it is merely making projections).

C: 表语从句不能省略that
D: 抓住核心prediction will reduce costs
E: for状从修饰主句动词predicts
do sth for sb，为某人做某事
A for 修饰reduce，政策削减了成本for这帮人，ok
B for修饰reduce，成本被政策削减for这帮人，ok；但by要么+doing，要么+纯名词，不接action noun，by one''s cost cuts用法错误，应该是reduce costs by cutting……，
C The government's prediction is 语意不够通顺，应该是government predicts that，另外by cuts用法错误
D for修饰reduce，ok，但句子的主干是政府的预测削减了成本，错误，不是预测削减了成本，是政策削减了成本
E for修饰predict，政府预测某事for这帮人，错误
但B中be reduced by sb.离得太远了，而且有修饰make a large number of long-distance calls的歧义
C，predictions is...表述繁复，用动词更简洁
B, by用法不当，相距动作太远，会造成歧义
A correct
(B) cost be reduced by…，被动语态表达不清晰。
(C) 名词prediction不及动词表达更确切;被动语态表达不清晰。
(D) 句子主语是prediction，缺少谓语;介词短语for…修饰对象错误，应该是修饰FCC，而不是the government。
(E) 介词短语for…修饰对象错误，that引导定语从句修饰rate cuts不及直接用’s rate cuts简洁。
c,表语从句缺that
d,prediction will greatly reduce costs, 不对
e,for.. predicts 不对
错选了B
（A）正确
（B）reduced和by之前隔太远，by会被误解成修饰call；被动没有A主动来的直接
（C）is that，漏掉了that
（D）for……修饰了prediction，不是为了……而预测，而是为了……而减少
（E）错误同D
长得和A很像
介词短语放句首，修饰主句的predict
For consumers and businesses...Government predicts...
意思为了consuers...政府才predicts.
同B，被动没必要
