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 rootlike 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.

(A) extending
(B) extends
(C) extended
(0) it extended
(E) is extending
I picked c .why c is wrong?


In this case, C ("extended") and A ("extending") are each participle modifiers. These are basically short versions of relative clauses. An easy way to see how they work is to add a relative pronoun (that, which, who, etc.) and a verb.

"... filigree of mushrooms and rootlike tentacles that is spawned by ... and that is extending ..."

Now we see that the sentence makes sense. The filigree of mushrooms and rootlike tentacles is spawned by (or created by) something else, but it actively does the act of extending.

If we tried this with C, it would say:

"... filigree of mushrooms and rootlike tentacles that is spawned by ... and that is extended ..."

This doesn't make sense. Now, the second modifier is in passive voice, so something else is extending the filigree of mushrooms and rootlike tentacles, as if someone is stretching them 30 acres.

Easy rule: -ed modifiers create a passive construction (the thing being modified does not do the action - something else is acting on it), while -ing modifiers create an active construction (the thing being modified does the action)

You might think there is an issue with parallelism between -ed and -ing modifiers; however, this is not an issue. Since each of these are participle modifiers, they are the same type of modifier, so they are parallel. It doesn't matter that one is active and one is passive.

A it is .


i go with paul's explanation.
The sentence says it is the largest living organism and it is still there in the Michigan forest. i.e. it is still extending or growing(maybe the fungus extends more than 30 acres now, so its"EXTENDING")

hope it helps

Re: Scientists have recently discovered what could be the [#permalink] New post 17 Jul 2013, 09:36
this is very hard because there are many new words, which make us unable to realize the intended meaning.

realize the meaning of ONLY ONE WORD, in this case, the word "rootlike" , to realize the intended meaning.

form the meaing of "rootlike", we guess that extending must be parallel with spawned. and A is correct.

it is very easy to explain this problem. but, How to do this, how to realize the intended meaning.

this question is unfair to the non native because non native have difficulty realizing the intended meaning.
I met this situation at the last gmat test .

VERY UNFAIR.

Scientists discovered the organism.
Most of the sentence describes this organism: largest, oldest, LIVING, etc. Many of you made the parallelism between "is" and "extends". But if we make "living" parallel with "extending"? Think about it. For me, what helped the most was the structure of the sentence. If you think of verbs inside the big modifier, then you get lost and confused with "is", "spawned", "extending", etc.


No. While the name is 'present' participle, they really have no tense (Present/Past/Future) of their own. Present participles 'derive' their tense from the 'main verb'.

He is running Vs He was running

Present Participle 'running' used in both sentences, but deriving the 'tense' (present and Past respectively) from the linking verb 'is/was'.

That aside, in the question under consideration, 'extends', as used in B cannot be used because 'extends' is a 'verb' and a 'verb' cannot be parallel with a 'participle' ('spawned'). Past Participle ('spawned') and Present Participle ('extending') can be perfectly parallel. Few examples are:

Tired but beaming, the athlete displayed the gold medal. (Tired- Past participle; beaming - Present participle)
The old lady's face, wrinkled but glowing, shone in the sun. (wrinkled - Past participle; glowing - Present participle).

The tougher part to see in this sentence is that 'extended', as used in C, would act as a proper verb (and hence would not be parallel with the Past participle 'spawned').

Lastly, the question is interesting, but that is only one clause in this sentence:

Scientists have recently discovered what could be the largest and oldest living organism on Earth

Rest all is an appositive modifier:

a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,300 years ago and extending for more than 33 acres in the soil of a Michigan forest.



hey ashish,

A noun || a noun
verb-ING || A noun
verb-ING|| verb-ED
werb-ED || A noun

does that hold true under all cases?

hi,
no they are not always parallel.

noun // noun // gerund(verb-ing acting as a noun)
verb-ing(acting as an adjective = participle) // verb-ed (this is also a participle and not a verb)

verb-ed===>this can be verb or participle(refer e-gmat article how to differentiate them)
verb-ed (acting as a verb) // verb


hope it helps.

Yes; basically "spawned" is acting as a past participle, while "extending" is present participle.

Participles are adjectives. That's my understanding. Please correct if I am wrong.

WaterFlowsUp and saumya23, you are correct.

WaterFlowsUp, another parallelism is:

Adjectives//participles (this should not surprise, because Participles are adjectives).'

Eg.

Just 5 feet 6 inches tall, and facing the mighty British empire, Gandhiji delivered.

tall is an adjective, while facing the mighty British empire is a participle.

Why is extending and spawned parallel participial phrases?


Scientists have discovered a giant fungus which is an interwoven filigree of mushrooms and rootlike tentacles. There are two characteristics of the fungus 1) It has been spawned by a single fertilized spore some 10,000 years ago. 2) It extends for more than 30 acres in the soil of Michigan.

These two characteristics have been shown in the original sentence in the form of Adjectival clauses spawned by...........ago AND extending for more............forest. The first clause is Verb-ed Modifier and the second one is Verb-ing Modifier

Since the first characteristic of Giant fungus has been described by a Adjectival Clause, The second characteristic also need to be shown in the form of a Adjectival clause, which is done in the original sentence. Hence the sentence is correct as written. Choice A is Correct

B) Extends acts as verb and can not parallel to Modifier spawned.

C) Extended also acts as verb and can not parallel to Modifier spawned. Also simple past tense extended indicates that the process of extending has been stopped, which is wrong. The fungus is still there and extending.

D) It extended is independent clause which can not be parallel to Modifier.

E) Incorrect for the same reason cited in Choice B.

Hope that helps!

A is the correct answer. This question is about the use of present vs past participle.
present participle is used to denote a present condition that still prevails
past participle is used to denote a completed action, usually in a passive mood

The sentence is definitely talking about the filigree:

filigree [of mushrooms and rootlike 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

What is b/w brackets is a prepositional phrase and remove it to make the sentence less cumbersome:

filigree 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

As you can see, the filigree spawned by X some 10,000 years ago. This warrants the use of past participle. Also, "spawned by" denotes passive voice which justifies the use of past participle.
As for the "extending", it is still prevailing today in the Michigan forest so you cannot use past participle "extended".

The present and past participles are used to describe the "filigree", they act as adjectives.


Hi Paul.

I decoded the meaning as : a giant fungus that is "<something> and [that] "extends"... So, here we are talking about two attributes of giant fungi instead of attributes of filigree.

OA should be B.

Am I correct ? Any reasons?

Anuj
