The first thing I noticed was that the underline is quite long. That’s a really good clue that I might have one of these sentences where the “splits” (or differences in the answer choices) might be less obvious. It’s more likely that big chunks of the sentence will move around, and the form of different pieces may change more substantially than usual. Basically, the longer the underline, the more likely these types of things are to happen.
The government predicts that, for <a certain group>, the <long modifier> rate cuts will reduce costs, though some groups disagree, <-ing modifier>.
The independent clause is one of the more complex structures: Subject Verb THAT Subject Verb Object.
The government predicts that the rate cuts will reduce costs.
A prepositional phrase (“for…”) set off by commas interrupts the independent clause. If something is going to get picked up and moved around in the answers, that’s a good candidate.
There’s also a long adjectival modifier describing the rate cuts: they’re “owned” by the Federal Communications Commission (that is, the FCC was responsible for them) and they occurred recently.
More simply, we’ve got:
Start of independent clause, modifier, rest of independent clause, dependent clause (introducing a contrast), modifier
The commas above correspond to the commas in the original sentence.
As we discussed in the first half of this 2-part article, it is far better to compare answers vertically than to read each answer choice horizontally. Your goal is always to find the best answer of the five; finding the best of something is by definition a comparison. On the problems we’re examining in this series, the comparisons are not as straightforward as they are on many problems.
So how do we still use this technique when the splits, or differences, aren’t as straightforward? We break the sentence into major parts – that’s why I simplified our original sentence, above.
Where are those parts in the various answer choices? Answer choice A is always the same as the original, of course. What about the others? (The commas represent the actual commas found in the sentences.)
A: start of independent clause, modifier, rest of independent clause
B: independent clause with a “that” modifier embedded (“that make…”)
C: start of independent clause), modifier, hmm… more of the independent clause? A new independent clause?
D: opening modifier, subject (with embedded “that” modifier: “that the FCC…”)
E: opening modifier, independent clause (with embedded “that” modifier: “that the FCC has made”)
In practice, I would start just with the independent clause in each choice, ignoring the rest of the sentence. Is each independent clause okay?
So, let’s see. Answer D seems to be missing an independent clause. That’s not good – every sentence has to have an independent clause or it’s not a sentence in the first place. Let’s check that one again:
“For consumers…” Okay, that’s just a modifier.
“the prediction that <something is true>” There’s a subject (prediction) but no verb to go with it (only the “that <something is true>” modifier has a verb).
The rest of the sentence is the non-underlined stuff, and we already decided that that part consisted of a dependent clause and a modifier. So, we don’t have a complete sentence. “Prediction” could be the main noun, but it has no verb! Eliminate D.
I also stumbled a little bit when trying to describe answer C’s independent clause:
“The government’s prediction is costs will be greatly reduced…”
I predict that costs will be greatly reduced…
I predict costs will be greatly reduced…
What’s the difference? Can I skip the word “that” in this sentence?
Turns out I cannot! Not in the above structure. If I want to predict something simple I can – let’s say that I want to convey the idea that things will be chaotic when the GMAT switches to the new version of the exam in 2012. I might say, “I predict chaos!” I wouldn’t say “I predict that chaos.” Why not?
We reserve the “that” structure for situations in which we want to predict something more complete. I predict that you will all study hard tonight. I predict that there will be lots of chaos when the GMAT switches to the new exam in 2012. I predict that costs will be greatly reduced…
All of those are more complex thoughts – we’re predicting things that go beyond just a single word – we’re predicting entire situations. For that, we need “that.” Eliminate C.
What else have we got? The original sentence contains the modifier “for consumers and businesses that make a large number of long-distance calls.” Where is that info in B and E? In choice B, the modifier isn’t set off from the main sentence. What difference does that make? Choice E places the modifier at the beginning of the sentence, also set off from the rest of the sentence by a comma. Does moving the modifier to the front change anything?
Modifiers refer to some other part of the sentence, so we have to make sure that they’re placed in such a way that they modify the correct thing. The word “for” is a preposition, so we’re dealing with a prepositional phrase modifier. When a prepositional phrase modifier is set off by commas, it is typically functioning as an adverbial modifier – that is, it is referring to some action in the sentence, as represented by a verb (the action). The modifier does not have to be placed right next to the verb, but it does have to be placed in such a way that it is clear which verb the modifier is “attached” to – that is, we don’t want to introduce confusion by placing the adverbial modifier too close to some other verb or action.
So what is happening “for (certain) consumers and businesses?” The rate cuts will reduce costs for these people and companies. The relevant action is “reduce costs.”
A and E both use commas to set off the prepositional phrase. In A, the prepositional phrase comes just before the clause that includes the verb “reduce,” so the placement in A is fine.
In E, the prepositional phrase comes just before “the government predicts.” That is one action: the government is predicting something. Is the government making this prediction for or on behalf of the consumers and businesses? No, that’s the wrong action. Rather, the government is predicting some other action – that costs will be reduced for consumers and businesses. The placement of the modifier in E is incorrect. Eliminate E.
What about choice B? The modifier comes immediately after “will be greatly reduced.” The placement here looks fine – the costs will be reduced for these groups. That meaning is correct.
We’re down to A and B. What else can we compare? Interesting. The opening part of B (“The government predicts that costs will be greatly reduced…”) sounds so much better than the opening part of A that it makes me wonder about the end of choice B. On really long choices, I’ve seen them do this before: the opening part sounds better but then something falls apart towards the end of that choice. If I’m not paying enough attention, I might not spot it, and they’ve just gotten me to fall into a trap. So I’m going to examine the end of B.
Let’s see: costs will be greatly reduced for <certain groups> that <have a certain characteristic> by <the thing that’s reducing the costs>
That last bit is problematic. The verb is in the passive voice (“costs will be reduced”). With passive voice, the subject is not the thing making the action happen. Rather, something else is (often, but not always, introduced using the preposition “by”). So the “by” preposition at the end is telling us who or what is responsible for reducing the costs. For example: “I ate the pizza” (active) or “The pizza was eaten by me” (passive).
As a general rule, we prefer active voice to passive voice. We can see active voice in choice A: “the rate cuts will greatly reduce costs.” The subject (rate cuts) is responsible for the action. So this is one reason to prefer A over B, but I’m going to take it a little further. The word “by” is a preposition and introduces a prepositional phrase. When a preposition immediately follows a noun with no comma between them, the default assumption is that the prepositional phrase refers to that noun. It doesn’t always have to 100% of the time, but that is the most likely scenario.
Is that accurate here? Does “by the Federal Communications Commission’s recent telephone rate cuts” modify “long-distance calls?”
No. I might say “I make a large number of long-distance calls by Skype” or “by satellite phone.” But I don’t make a large number of long-distance calls by rate cuts. The fact that the sentence can initially be read in this nonsensical way introduces an ambiguity and the GMAT doesn’t like ambiguity. Now we have two reasons to prefer A over B, and that’s definitely enough to pick A and move on!
The correct answer is A.
Key Takeaways for Long Underlines + Jumbled Sentences on SC:
(1) Long-underline sentences are more likely to be “jumbled” – that is, to move big chunks of the sentence around and even to change what information is located in the dependent vs. independent clauses. When you see this happening, break the sentence down into those chunks (commas are often great natural separators) and figure out the role of each chunk.
(2) When you use the “chunk” strategy, you will often start in one of two places: either start with the first chunk of the original sentence and go find the location of that chunk in subsequent answer choices, or start with the independent clause in each answer choice, wherever that might be. The more complicated the sentence, the more likely you are to concentrate on the independent clause first.
(3) These kinds of sentences also typically test the placement of the chunks – is the modifier or other “extra” info in the right place relative to the other pieces of information? In this case, we were able to eliminate some choices because the modifiers were placed incorrectly relative to the other words in the sentence.
