“ED FORMS” – VERBS OR MODIFIERS

Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and root like tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.

This is probably one of the most discussed problems in GMAT Verbal SC section. This sentence is a cake walk for those who understand verb-ing and verb-ed modifiers thoroughly, and is confusing to the hilt for those who have just started to learn these concepts. The tactfully crafted answer choices of this problem keep bringing this question on various forums for discussion and detailed explanation. So let’s take a look at those interesting answer choices:

A. extending
B. extends
C. extended
D. it extended
E. is extending

In the first glimpse, the sentence looks simple and easy. You scan the sentence, discover the word “spawned”, look at conjunction “and”, think, “Oh! Parallelism dude. How simple!”, mark Choice C. But all the excitement is robbed off by the Answer Key page that says Choice A is the correct answer.

So where did you go wrong? Aren't “spawned” and “extended” grammatically parallel? They both have the same structure. The instinct (especially of the non-natives) is to believe that words with “ed” are simple past tense verbs. So if you took “spawned” to be the simple past tense verb, you looked for the same for “extending” and marked “extended”. You got the incorrect answer.

VERB-ED – CAN BE SIMPLE PAST TENSE OR MODIFIER

So, what is happening in this sentence? “Extended” fits as simple past tense verb and looks parallel to “spawned”. Then how can “extended” be incorrect? Well, the answer is that Verb-ed forms can be used in two ways –One as verb in simple past tense and the other as modifier (also called Verb-ed modifiers) and in this case it is used as the latter (explained later). In essence, the same word, for example extended, can assume the role of a verb in simple past form or that of a modifier. The challenge in the question is to determine whether “spawned” and extended” are verb-ed modifiers or just the verbs and then decide in what form should “extended” be used.

To determine that, let’s examine two simple examples:

a. The company extended the training period for the interns. – extended = simple past tense
b. The training period extended last year made many interns unhappy. – extended as verb-ed modifier
Let's analyze the meaning of sentence a. The sentence clearly conveys that that the company did the job of extending the training period for the interns. The word “extended” works as “verb” in this sentence.
Sentence b means that many interns became unhappy because the training period was extended. In this sentence, the verb is "made". "Extended" is the verb-ed modifier that is giving additional information about "the training period". So, here we see that the same word "extended" can work as a verb and as a modifier, depending upon how it has been used in the sentence. In fact, most of the words can be written as “verb” as well as “modifier” if we add “ed” to them. “Spawned” is also one of them.

If you want to know how to tell whether a verb-ed word is a simple past tense verb or a modifier, read in the following section about this simple test that can be very handy.

There is a simple test we can perform to find out whether the verb-ed is a verb in simple past tense or the verb-ed modifier. Here is the test:

Let’s have another look at both the examples above:
a. The company extended the training period for the interns.

The subject of the sentence above is “The Company” . Now ask yourself, “Is the subject the doer of the verb?” In other words, did the company extend the training. The answer is yes it did. The Subject Verb pair makes sense. Hence, in this sentence, extended is used as a verb in simple past.

b. The training period extended last year made many interns unhappy.

The subject here is “The training period”. The next word is the verb-ed “extended”. Is it a verb or a modifier? Ask this question: “Did “the training period” do the action of “extending”? The answer is “No”. The action of extension was not done by the training period. In other words, the Subject-Verb pair does not make sense. This tells you that “extended” is a verb-ed modifier here and not the verb.

Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and root like tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.

Now let us apply this test on the “giant fungus”. After cutting the flab, this is the core that we get:
…a giant fungus… spawned by a single fertilized pore some 10,000 years ago…

So let’s ask, did “a giant fungus” do the action of “spawning”? The answer is “no” because it is clearly mentioned in the sentence that the action of spawning was done by “a single fertilized pore”. Hence, the litmus test confirms that “spawned” is a verb-ed modifier.

Therefore, to maintain parallelism we need to use a form of “extend” that is used as a modifier. Note that “extended” CAN be a verb-ed modifier. However, we need to find out if this form works in this sentence as a modifier:

…a giant fungus… extended for more than 30 acres in the soil of a Michigan forest.

Did “a giant fungus” do the job of extension? Yes, it did. It is the giant fungus that extends for more than 30 acres. This means that “extended” will work as simple past tense verb in this sentence and not as a modifier. This is the reason why “extended” cannot be used since a verb CANNOT be parallel to a verb-ed modifier.

Let’s once again quickly look at the answer choices:
A. extending
B. extends
C. extended
D. it extended
E. is extending

A quick scan of these choices will tell you that all the answer choices B, C and E are verbs in different forms while Choice E is a clause. Choice A “extending” is the only modifier that describes one of the characteristics of “a giant fungus”. Hence, verb-ed modifier “spawned” and verb-ing modifier “extending” are parallel entities because they both perform the same function, although they differ structurally.

HOW VERB-ED MODIFIER IS DERIVED

This section is for those who have the grammarian like quest for knowledge. We will explain here in detail how verb-ed modifiers are derived. This knowledge is not imperative to take the GMAT, but is more for personal understanding as to why verb-ed modifiers work the way they do. So let’s bring the sentence with verb-ed modifier back here:
a. The training period extended last year made many interns unhappy.

Now this sentence can be written as:

i. The training period that was extended last year made many interns unhappy.

So, we have a relative pronoun clause here that is written in simple past tense in passive voice. Per the grammar rules, verb-ed modifiers are derived by removing the relative pronoun modifier that is written in passive voice by removing “the relative pronoun” and “the helping verb” (is/are/am/was/were). Hence we derive:
that was extended last year = was extended last year = extended last year

Let’s take another example:
b. A good leader who is followed by the mass and is respected for his benevolent qualities is always remembered for several generations.

So here we have two relative clauses with passive verbs “is followed” and “is respected”. Let’s turn both of them into verb-ed modifiers.
Who is followed by the mass = is followed by the mass = followed by the mass
Who is respected for his benevolent qualities = is respected for his benevolent qualities = respected for his benevolent qualities

c. A good leader followed by the mass and respected for his benevolent qualities, is always remembered for several generations

Notice that active verbs in relative pronoun clause cannot be turned into verb-ed modifiers. Let’s try this:
a. A leader who guides his followers honestly earns immense respect from the mass.
If we apply the rule to derive verb-ed modifier here, this is what we will get:
Who guides his followers = guides his followers

Notice the limitation with the sentence containing a relative pronoun in active voice and simple present tense. There is no question of getting verb-ed modifier here because originally there is no verb-ed word in this sentence.
This method will not work even if we change the tense of the above sentence:
a. A leader who guided his followers honestly earned immense respect from the mass.

Who guided his followers = guided his followers
Now let’s put this verb-ed modifier phrase in the sentence:

a. A leader guided his followers honestly earned immense respect from the mass.
No need to say that this sentence is a fragment because here “guided” is the simple past tense verb and not a verb-ed modifier. “earned” again is a verb . So this sentence has two verbs that are not connected properly. We landed up with this disaster because we tried to make the verb-ed modifier out of the verb in active voice in the relative clause.

People who are fluent in the language do not need to know the basics behind the derivation of the verb-ed modifiers because they intuitively know that sentence 1 is correct but sentence 2 is incorrect. They may not be able to pin point the reason for the same, but they can distinguish right from wrong. But people who are not that fluent in this language may get confused about the above. For example, one of the students asked me the following question about OG12#85:

Can I omit “that” from this sentence or is “that” required?

Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization that flourished at the same time as the civilizations …

The answer = “that” is required because if you omit it, the sentence will be a run-on sentence. But consider another version of this sentence:

Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization that was destroyed multiple times by flooding of Indus river…

Now in this sentence, “that” can be omitted (obviously along with “was”)

Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization destroyed multiple times by flooding of Indus river…

In essence, this information helps build your knowledge about the sentence structure, which in turn results in more solid foundation.

Verb-ed modifiers are covered in detail in the concept titled “Modifiers – verb-ing”. This concept is available in the free preview of Sentence Correction course. You will need to login at e-gmat.com to access this concept.

Identify whether the underlined words are verbs or verb-ed modifiers.

1. Like birds today, Archaeopteryx had feathers that were fully formed.

2. Our powers of color vision are derived from cells in our eyes called cones, three types in all, each triggered by different wavelengths of light.

3. As Joel Bregman hoped, dozens of young stars turned up in each of the three dead galaxies—and as an added surprise, they even appeared in Messier 105.

4. Dark matter might actually be produced at the energies explored by the world’s most powerful particle accelerator, the Large Hadron Collider (LHC).

5. A leader guided by sound principles earned immense respect from the masses.

6. A company founded on sound business principles achieves much higher success.

7. The lamp decorated with stars filled the child’s room with innocent beauty.

Correct these sentences if you feel they are incorrect.
1. The lamp decorated the child’s room filled his room with innocent beauty.

2. A leader guided his followers earned immense respect from the masses.

1. Like birds today, Archaeopteryx had feathers that were fully formed. <-- modifier

2. Our powers of color vision are derived from cells in our eyes called cones, three types in all, each triggered by different wavelengths of light.
Called = modifier; triggered = verb

3. As Joel Bregman hoped, dozens of young stars turned up in each of the three dead galaxies—and as an added surprise, they even appeared in Messier 105. Hoped = verb; turned = verb; added = modifier; appeared = verb <-- this sentence is definitely the most challenging.

4. Dark matter might actually be produced at the energies explored by the world’s most powerful particle accelerator, the Large Hadron Collider (LHC). explored = modifier

5. A leader guided by sound principles earned immense respect from the masses. guided = modifier; earned = verb

7. A company founded on sound business principles achieves much higher success. founded = modifier

8. The lamp decorated with stars filled the child’s room with innocent beauty. decorated = modifier; filled = verb

Correct these sentences if you feel they are incorrect.
1. The lamp decorated the child’s room filled his room with innocent beauty.
The lamp which decorated the child's room filled his room with innocent beauty.
2. A leader guided his followers earned immense respect from the masses.
A leader who guided his followers earned immense respect from the masses.

SOLUTION

Identify whether the underlined words are verbs or verb-ed modifiers.

1. Like birds today, Archaeopteryx had feathers that were fully formed.
Formed = simple past tense verb. In the relative pronoun clause, “that” is the subject that stands for “feathers” and the verb for this subject is “were formed”.

2. Our powers of color vision are derived from cells in our eyes called cones, three types in all, each triggered by different wavelengths of light.
Called & triggered = verb-ed modifier
Litmus Test: Did the “eyes” do the action of calling? No. Hence, it’s a modifier.
Did “each” do the job of triggering? No. Different wavelengths of light did that job. Hence, “triggered” is the modifier.

3. As Joel Bregman hoped, dozens of young stars turned up in each of the three dead galaxies—and as an added surprise, they even appeared in Messier 105.
Hoped, turned & appeared = simple past tense verbs for subjects “Joel Bregman”, “dozens of young stars” and “they” respectively.
Added = modifier that modifies “surprise”.

4. Dark matter might actually be produced at the energies explored by the world’s most powerful particle accelerator, the Large Hadron Collider (LHC).
Explored = verb-ed modifier
Litmus Test: Will “the energies” do the job of exploring? No. The world’s most powerful particle accelerator, the Large Hadron Collider might do that action. Hence, “explored” is the modifier.

5. A leader guided by sound principles earned immense respect from the masses.
Guided = verb-ed modifier, earned = simple past tense verb for the subject “A leader”.
Litmus Test: Did a leader do the action of guiding? In this context, no. “Sound principles” guided “a leader”. Hence, guided is the modifier.

6. A company founded on sound business principles achieves much higher success.
Founded = verb-ed modifier
Litmus Test: Did a company do the action of founding? In this context no. May be the founder of the company did that job. Hence, founded is the verb-ed modifier.

7. The lamp decorated with stars filled the child’s room with innocent beauty.
Decorated = verb-ed modifier, filled = simple past tense verb for the subject “The lamp”.
Litmus Test: Did the lamp do the action of decorating. No. Hence, it is the modifier.

Correct these sentences if you feel they are incorrect.

1. The lamp decorated the child’s room filled his room with innocent beauty. = Incorrect
Correct = The lamp that decorated the child’s room filled his room with innocent beauty.

2. A leader guided his followers earned immense respect from the masses. = Incorrect
Correct = A leader who guided his followers earned immense respect from the masses.

Another example of how the verb form and verb-ing form can change the meaning and logic of a sentence:

John worked hard on the project, coordinating with his professors, running simulations, and discussing the results with his peers.

In the above sentence, 'coordinating with his professors, running simulations, and discussing the results with his peers.' tells us how John worked hard. The main part is that John worked hard.

If we change the verb form:

John worked hard on the project, coordinated with his professors, ran simulations, and discussed the results with his peers.

This completely changes the meaning of the sentence and gives equal weight to the four parts of the sentence. Now 'coordinated with his professors, ran simulations, and discussed the results with his peers.' no longer describes how John worked hard; rather it becomes an extension of the things describing what John did.

I think this is a good lesson in meaning/logic VS parallelism. Sometimes you may not have to make all verbs parallel if it drastically changes the meaning of the sentence.

just my 2c...

Hi eGMAT,
Going by your 'Takeaway', if the subject of the sentence IS NOT the doer of the action then is there any exception that still the verb-ed form in that sentence,IS NOT the MODIFIER...?

Can you show some examples ?

Hi Debayan,

A verb-ed word will be either a verb or a verb-ed modifier. If it is a verb, it will certainly have a Subject or some doer (if the sentence does not have any grammatical error). If it is not a verb, then the verb-ed word has to be a modifier.

Hope this helps.
Thanks.

Understood the concept on Verb-ed Modifiers. Could you clarify the below question, in line with Verb-ing modifiers

The increased popularity and availability of televisions has led to the decline of regional dialects, language
variations which originate from diverse ethnic and cultural heritages and perpetuated by geographic isolation.

A. which originate from diverse ethnic and cultural heritages and perpetuated
B. that originated from diverse ethnic and cultural heritages and perpetuated
C. originated from diverse ethnic and cultural heritages and perpetuated
D. originating from diverse ethnic and cultural heritages and perpetuated
E. originating from diverse ethnic and cultural heritages and perpetuating

Hi there,
The increased popularity and availability of televisions has led to the decline of regional dialects, language variations which originate from diverse ethnic and cultural heritages and perpetuated by geographic isolation.

First of all, I would recommend you to read the following articles that describe in details various usages of “verb-ing” modifiers.
usage-of-verb-ing-modifiers-135220.html
verb-ing-modifiers-part-2-in-our-first-article-on-verb-ing-135567.html

Now let’s solve this problem at hand.

Meaning Analysis:

Popularity of television has resulted into decline of regional dialects. These regional dialects are language variations. Two characteristics of dialects have been presented:
a. they originate from diverse ethnic and cultural heritages and
b. they are perpetuated by geographic isolation

Error Analysis:

The first characteristic of dialects has been presented in clause “which originate”. Hence the second characteristic must be presented in the same format. Now “which” can be taken to be understood in the case of second clause. However, notice the construction “perpetuated by geographic isolation”. This means dialects did not do the action of perpetuating. The action was done on them Hence, we need a passive voice verb here. To maintain parallelism, the correct verb should be “are perpetuated by…”. In absence of “are” before “perpetuated”, this word acts as a verb-ed modifier that cannot be parallel to a clause.

PoE:

A. which originate from diverse ethnic and cultural heritages and perpetuated: Incorrect for the reason stated above.

B. that originated from diverse ethnic and cultural heritages and perpetuated: Incorrect. Same error as in choice A.

C. originated from diverse ethnic and cultural heritages and perpetuated: Incorrect. “originated” here is a simple past tens verb. This leads to a run-on construction where the two independent clauses are connected by a comma.

D. originating from diverse ethnic and cultural heritages and perpetuated: Correct. “originating”, the verb-ing modifier and “perpetuated”, the verb-ed modifier, correctly modify “language variations”. These two forms of modifiers are parallel because they both perform the same function.

E. originating from diverse ethnic and cultural heritages and perpetuating: Incorrect. Verb-ing modifier “perpetuating” incorrectly modifies “language variations”. This modification means that the action of “perpetuating” was done by “language variations” .

Hope this helps.
Thanks.

E. originating from diverse ethnic and cultural heritages and perpetuating: Incorrect. Verb-ing modifier “perpetuating” incorrectly modifies “language variations”. This modification means that the action of “perpetuating” was done by “language variations” .

Hope this helps.
Thanks.

Thanks for the profound explanation.

Couple of poignant after thoughts. Please confirm. (I have gone through the sessions on Verb-ed and Verb-ing modifiers.)

Language Variations is the doer of only of the actions i.e. Originating, whereas the Geographic isolation is the doer of perpetuating.

Can we say, for the sake of time, that whenever we spot a Verb-ing modifier without comma we can safely assume that it modifies the previous eligible noun/noun phrase and never functions as a verb, until -ing is present with helping verbs such as was, is, are etc.

When we encounter a Verb-ed modifier, we need to be more cautious and confirm whether it is a simple past tense or a modifier?

Otherwise we can always say for Option D & E that since Language Variations is the doer of the action Originating, it functions as the verb.

In Short, the Litmus test mentioned in the tutorial only applies to Verb-ed modifiers and not Verb-ing modifiers.

Hi Sinner1706,

1. When a verb-ing modifier is not preceded by a comma, it always modifies the previous noun entity - a single word noun or a noun phrase.
2. It is correct that just a verb-ing word cannot function as a continuous/progressive verb tense unless it is preceded by such helping verbs as is/am/are/was/were etc.
3. When we see a verb-ed word, we must make sure whether it is a simple past tence verb or a modifier. This is so because a verb-ed word can play both these functions. A verb-ed word is generally taken to be a simple past tense verb when it may be functioning as a modifier.
4. There is no Litmus Test for verb-ing modifier because just the verb-ing word CANNOT function as progressive verb tense if it is not preceded by a heping word. There is no way of confusing just the verb-ing word with a verb.

Hope this helps.
Thanks.

Understood the concept on Verb-ed Modifiers. Could you clarify the below question, in line with Verb-ing modifiers

The increased popularity and availability of televisions has led to the decline of regional dialects, language
variations which originate from diverse ethnic and cultural heritages and perpetuated by geographic isolation.

A. which originate from diverse ethnic and cultural heritages and perpetuated
B. that originated from diverse ethnic and cultural heritages and perpetuated
C. originated from diverse ethnic and cultural heritages and perpetuated
D. originating from diverse ethnic and cultural heritages and perpetuated
E. originating from diverse ethnic and cultural heritages and perpetuating

Hi there,
The increased popularity and availability of televisions has led to the decline of regional dialects, language variations which originate from diverse ethnic and cultural heritages and perpetuated by geographic isolation.

First of all, I would recommend you to read the following articles that describe in details various usages of “verb-ing” modifiers.
usage-of-verb-ing-modifiers-135220.html
verb-ing-modifiers-part-2-in-our-first-article-on-verb-ing-135567.html

Now let’s solve this problem at hand.

Meaning Analysis:

Popularity of television has resulted into decline of regional dialects. These regional dialects are language variations. Two characteristics of dialects have been presented:
a. they originate from diverse ethnic and cultural heritages and
b. they are perpetuated by geographic isolation

Error Analysis:

The first characteristic of dialects has been presented in clause “which originate”. Hence the second characteristic must be presented in the same format. Now “which” can be taken to be understood in the case of second clause. However, notice the construction “perpetuated by geographic isolation”. This means dialects did not do the action of perpetuating. The action was done on them Hence, we need a passive voice verb here. To maintain parallelism, the correct verb should be “are perpetuated by…”. In absence of “are” before “perpetuated”, this word acts as a verb-ed modifier that cannot be parallel to a clause.

PoE:

A. which originate from diverse ethnic and cultural heritages and perpetuated: Incorrect for the reason stated above.

B. that originated from diverse ethnic and cultural heritages and perpetuated: Incorrect. Same error as in choice A.

C. originated from diverse ethnic and cultural heritages and perpetuated: Incorrect. “originated” here is a simple past tens verb. This leads to a run-on construction where the two independent clauses are connected by a comma.

D. originating from diverse ethnic and cultural heritages and perpetuated: Correct. “originating”, the verb-ing modifier and “perpetuated”, the verb-ed modifier, correctly modify “language variations”. These two forms of modifiers are parallel because they both perform the same function.

E. originating from diverse ethnic and cultural heritages and perpetuating: Incorrect. Verb-ing modifier “perpetuating” incorrectly modifies “language variations”. This modification means that the action of “perpetuating” was done by “language variations” .

Hope this helps.
Thanks.

Great explanation. One question or rather just a thought.

In both D and E, perpetuating and perpetuated are modifying language variations. However perpetuated is correct.
Can we say that for verb ing modifier, the modified entity should associate to the action presented by the modifier. However that need not be true for verb-ed modifier?

Hi scp,

The comma + verb-ing modifier by default associates with the action of the preceding modified clause in that this modifier presents either additional information on the "HOW" aspect of the action in the preceding clause or the result of the action of the preceding clause.

The thing we must take a note of is that the action denoted by the verb-ing modifier must make sense with the subject of teh modified clause.

The reason why "perpetuating" in Choice E is incorrect because the choice now suggests that "language variations" did the action of "perpetuating". This is not true because the action of "perpetuating" was done on "language variations". This is the reason why we need verb-ed modifier "perpetuated" here.

This is the reason why "originating" is the correct modifier to modify "language variations" because "language variations" did the action of originating and hence makes sense with subject. You can study any correct sentence with coma + verb-ing modifier. This point is mentioned in our article as well.

Hope this helps.
Thanks.

Correct these sentences if you feel they are incorrect.

1. The lamp decorated the child’s room filled his room with innocent beauty. = Incorrect
Correct = The lamp that decorated the child’s room filled his room with innocent beauty.

2. A leader guided his followers earned immense respect from the masses. = Incorrect
Correct = A leader who guided his followers earned immense respect from the masses.

For the first sentence-did the lamp do the action of decorating on its own? I guess not! Then how this sentence "The lamp that decorated the child’s room filled his room with innocent beauty." can be correct ? Please help me understand it.

For the second sentence-if we write this as 'A leader guided his followers and earned immense respect from the masses'...Will that be wrong ? Please explain.
