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 fertilised 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
(D) it extended
(E) is extending

Would "that extends" be a correct choice?
A giant fungus that is an interwoven filigree of mushrooms..... and that extends for more than...in Michigan forest. Can these be parallel?

Hi iwill
Thanks for the reply.I have read that article and its great.Here my question was not regarding parallelism of "spawned and extending" but regarding the two depended clauses starting with "that" as i have specified.

The most important clue in this sentence is AND … the word AND mandates Right to Left strict parallelism. To the right of AND is ―extending‖ … to check parallelism, we have to understand the role of the word ―extending‖. It is not a verb as -ING forms alone are never verbs. So it can be a noun or an adjective. In this sentence the word ―extending‖ is describing something … we need to know what it is describing.
If we read further … ―extending for more than 30 acres in the soil of a Michigan forest‖ can describe the largest organism (30 acres is really LARGE), which is the same as ―giant (large) fungus‖ or ―interwoven (interconnected, large) filigree‖. ―Mushrooms and root-like tentacles‖ of a single plant can‘t extend for 30 acres … their filigree (wire formed into delicate tracery such as filigree foliage) can. So the word ―extending‖ surely describes ―organism‖.
As the word ―extending‖ describes something, it is an adjective. And the word ―extending‖ is written after the word AND … so we must find another adjective (that describes the organism) to the left of AND. We have the word ―spawned‖ before AND. ―Spawn‖ (meaning: produce or generate, especially in large numbers and undesirably) cannot describe tentacles, as tentacles of a plant cannot extend for 30 acres and can‘t get generated in large numbers. Also, the fact that ―a single spore‖ was responsible for the whole 30-acre growth (happening for the last 10,000 years) makes sure that the word ―spawned‖ describes the organism …
So we have 2 adjectives: ―spawned‖ and ―extending‖, both describing the organism … perfectly parallel … option A must be correct.
Option B: ―extends‖ is a verb … but there is no verb parallel to ―extends‖ before the word AND … Incorrect.
Option C: ―extended‖ is also an adjective. But this signifies intention whereas the given action of extending is completely unintended. So this is the wrong adjective.
Imagine the two sentences:
The road extended from A to B was found to be skewed by the local authorities. Here, the word ―extended‖ means that somebody intentionally extended the road. Past participles show intention.
The smoke coming out of the building corroborated the suspicion that the building had caught fire. Here the word ―coming‖ is unintended. Present participles show no intention.
There's really no point in deciding which of these roles ―extended‖ is playing―the point is that both interpretations produce incorrect answers! In an appropriate context, ―extended‖ could be either a past participle or a past-tense verb. Most importantly, if either of these interpretations works, then the sentence is correct.
Imagine the sentence:
The new state highway, built in 2007 and extended for an additional five miles in 2009, is now the busiest road in the area. --> here, ―extended‖ is a past participle.
The state highway extended for fifty miles before it was razed in 1985. --> here, ―extended‖ is a past-tense verb.
Option D: ―it extended‖ is a verb … but there is no verb parallel to ―extended‖ before the word AND … Incorrect.
Option E: ―is extending‖ is a verb … but there is no verb parallel to ―is extending‖ before the word AND … Incorrect.

moreover do u have any option with that or do u have that before extending in the non underlined portion?no. so why r u looking for a that and that parallelism. understand the function of extending. its a modifier describing a noun. ok i think u r asking where that and that would have been grammatically possible. yes. but i think the meaning wouldn have been clear . he there r two reason why the scientist think that it is the oldest organism 1. coz its spawned and 2. extending bla bla...
Hope this helps

Hi there,

In this case, the two modifiers 'spawned' and 'extending' should be parallel to each other. So, while 'that extends' could be used to create parallelism with 'that is', it would change the intended parallelism of the sentence.

Meghna
