There’s a type of sentence known among linguists and grammar mavens as a “garden path” sentence. These sentences earned this name by leading readers “down the garden path” — you think the sentence is going in one direction, but halfway through, you suddenly realize that it’s saying something else entirely. Here’s the classic example:

The horse raced past the barn fell.

Believe it or not, this sentence is grammatically correct. The core of the sentence is The horse fell. “Raced past the barn” is just a modifier describing the horse. The sentence is equivalent to this one:

The horse that was raced past the barn fell. 

The second sentence is written much more clearly. The phrase “that was” makes it obvious that a modifier is about to start, so you don’t expect raced to be the main verb of the sentence. Yet grammatically, they’re both technically fine. It’s okay to start modifiers with that was, but it’s also okay to start modifiers with just a past participle, like in these examples.

The man trampled by the horse has made a full recovery.

                The mural created last year won several awards.

In English grammar, it’s often okay to leave out the that was or who was. Doing so sometimes leads to a poorly written or difficult to read sentence, which is why writers are cautious about it. But the GMAT tests grammar and logic, not clear writing. The right answers to GMAT Sentence Correction questions will sometimes phrase things in awkward-sounding or unclear ways.

Another example is the infamous appositive. Here’s a grammatically correct sentence from the GMAC’s GMATPrep software:

Architects and stonemasons, the Maya built huge palace and temple clusters without the benefit of animal transport or the wheel.

The phrase “architects and stonemasons” at the beginning of the sentence throws many readers off. It seems as if two nouns have been stuck onto the front of the sentence with no attention to how they fit in. This type of modifier — in which a noun, set off by commas, can modify another noun — sounds awkward to many readers. We almost never use appositives in speech, and many writers rarely use them. However, they’re acceptable in formal English grammar, and they’re acceptable on the GMAT.

In his recent self-help book, the author and diet guru proposed a revolutionary new way of losing weight, a method that allowed dieters to eat dessert after every meal and do only minimal exercise.

The phrase beginning with “a method” is also an appositive. Making matters worse, the appositive contains yet another modifier inside of it: that allowed… modifies method. Yet the sentence is still grammatically correct! You don’t need to memorize the technical details of this type of modifier, but you should remember that even if they sound strange, that’s just because they’re rare. They’re grammatically correct and okay on a GMAT Sentence Corrrection problem.

I’ll leave you with one last bizarre sentence. You might think that it’s never possible to have two verbs right next to each other! But this sentence would be correct on the GMAT:

The threat of dehydration that desert reptiles, such as the northern blue-tongued skink and the red diamond rattlesnake, face results from the dry and hot environment.

This sentence sounds strange because of the two verbs, face and results, that appear immediately next to each other. It’s also difficult to read because these two verbs can both also be used as nouns! However, structurally and grammatically, the sentence is correct. It actually has two modifiers nested inside of each other. The core is The threat of dehydration results from the dry and hot environment. The next phrase, that desert reptiles face, modifies threat of dehydration. And finally, such as the northern blue-tongued skink and the red diamond rattlesnake modifies reptiles.

The threat of dehydration that desert reptiles, such as the northern blue-tongued skink and the red diamond rattlesnake, face results from the dry and hot environment.

That’s a hideous sentence — but it’s not wrong. And what can you do about this? Here are three major ideas to use as you practice Sentence Correction:

  1. Learn the grammatical constructions that tend to sound wrong to you, so that when you see them on the test, you’ll know not to eliminate them by accident.
  2. It’s okay to use your ear, but use grammar first. GMAT Sentence Correction tests grammatical and logical rules, not writing style. Your ear might not know the difference between wrong grammar and just plain lousy writing.
  3. Don’t ever eliminate an answer choice just because it seems poorly written — unless it’s totally incomprehensible, or you can’t find any more grammatical or logical issues to work with.

If you’re anything like me, you read books and articles avidly (although maybe less often than you did in college), and you’ve been told that you’re a good writer (although you definitely write less than you did in college). The Sentence Correction portion of GMAT Verbal seems like it should be easy for you: fix anything that sounds like bad writing, and you’ll do well here.

Here’s What to Do When You Can’t Find the “Split” on GMAT Sentence Correction

by

In GMAT Sentence Correction, a “split” is a clear difference among the answer choices that allows you to identify and eliminate several incorrect answers. You can’t always find a perfect, straightforward answer choice split to work with in every Sentence Correction problem. Sometimes, most or all of the sentence is underlined, and the answer choices seem completely different from each other. When this happens, don’t fall back on bad habits. Even if you can’t find a great split, you can take a smart, fast approach to the problem. Let’s work through that approach using the following problem, from the GMAC’s GMAT Prep software. Read more

Have you been following our grammar tips series? We’ve already talked about opening modifiers and noun modifiers. We’re almost done with this much-feared topic. If you’re still having problems, it’s probably with adverbial modifiers.

These can be the most overwhelming, so let’s break them down now. Back to our favorite modifier-riddled sentence:

Barking ferociously, the dog, which was known to be vicious, ran down the street, chasing the boy who had been poking at it just moments before.

An adverbial modifier is something that describes almost anything in the world that is not a noun. There’s actually a one-word adverbial modifier in our ferocious dog sentence (or, put far more simply, an adverb). Go back and see if you can find it. Read more
