Mike,
Yeah, it makes a lot of sense to me. But, I think I didn't ask my doubt very clearly in the previous post, so could you please help me on the below?
My doubt is only regarding non-essential modifiers (past and present participial phrases preceded by a comma).
Let us first look at the past participial modifier. Typically, the sentence looks as below:
<main clause>, <verb-ed modifier>.
The verb-ed modifier modifies the closest noun preceding the comma and belonging to the main clause.
Ex: Diabetes ranks as the nation’s third leading cause of the death, surpassed only by heart disease and cancer. (The past participial phrase is modifying the noun 'third leading cause'.)
Now, my doubt is whether the below is also correct on the GMAT.<main clause>,non-essential modifier ending with some noun, verb-ed modifier modifying the noun in the preceding modifier.
Ex: Diabetes, the nation's third leading cause of death, surpassed only by heart disease and cancer, is a deadly disease.
Now, let us look at the present participle (verb-ing)Typically the sentence looks like the below:
<main clause>,<verb-ing modifier modifying the verb or the main clause>.
Ex: Sam is the third fastest runner in school, running at 10 miles per hour.
I want to know if the below is also correct on the GMAT.<main clause>,non-essential modifier,<verb-ing modifier intending to modify the verb of the main clause or the main clause>.
Ex: Sam is the third fastest runner in school, surpassed only by John and Ronnie, running at 10 miles per hour. (If it is wrong, then is it wrong because of the missing conjunction?)
Ex: Sam is the third fastest runner in school, surpassed only by John and Ronnie and running at 10 miles per hour. (Is this a correct sentence on the GMAT?)
If so, can we say that
the verb-ing modifier or present participle modifying a verb or clause should only be preceded by a clause that it intends to modify?Dear
gmatter0913,
So, let's look at these sentences.
Diabetes ranks as the nation’s third leading cause of the death, surpassed only by heart disease and cancer.
This sentence, which is suspiciously similar to OG13 SC #6, is perfectly correct. It's debatable whether the participle "
surpassed" is a noun modifier, modifying "
third leading cause of the death", or a verb modifier, modifying "
ranks," or something that modifies the entire clause. One could make any of those cases.
Diabetes, the nation's third leading cause of death, surpassed only by heart disease and cancer, is a deadly disease.
This is awkward. I don't think there's something definitively wrong with it, but it sounds funny. The reason it's not entirely wrong is that the first modifier is an
appositive phrase. See:
https://magoosh.com/gmat/2012/gmat-gramm ... e-phrases/Appositives are very different from other non-essential modifiers, because they are restatements of the noun. What's between the commas is another way of stating the subject, so a modifier that modifies it is modifying the subject. If you wanted to demonstrate the effect of an intervening non-essential modifier, unfortunately you chose the worst possible example in choosing an appositive phrase. Here's what I think you were trying to demonstrate,
Amyotrophic lateral sclerosis, which killed Lou Gehrig, associated with loss of motor control, has no cure.
That sentence is a total trainwreck. The participle "
associated" is a noun-modifier that should touch the noun it modifiers, but instead of touching ALS, it incorrect touches Gehrig. That involved the past participle as a noun-modifier. Here's another:
California was admitted to the US in 1850, nine years before Oregon's admission, propelled to importance by the discovery of gold at Sutter's Mill.
Hmmm. Questionable. It's hard to imagine this as a correct answer on the GMAT SC. Participle modifiers are flexible, but this is a bit over the top. The funny thing is --- it sounds OK. It's very colloquial. Nevertheless, I suppose we would have to call this a misplaced modifier, and hence wrong. Do these two examples answer your question?
Sam is the third fastest runner in school, running at 10 miles per hour.
Correct.
Sam is the third fastest runner in school, surpassed only by John and Ronnie, running at 10 miles per hour.
Wrong, because the absence of the conjunction creates ambiguity about the target noun of the second participle.
Sam is the third fastest runner in school, surpassed only by John and Ronnie and running at 10 miles per hour.
This is 100% grammatically correct, but I'm not completely sure that such an unconventional structure would be tested on the GMAT.
Notice that a present participle modifying a verb or clause can come
before the clause or
after the clause:
Running at 10 miles per hour, Sam is the third fastest runner in school.
I'm not sure whether all this answers your questions.
Mike
