Kudzu, an Asian vine that has grown rampantly in the southern United S

Hi techiesam, I believe you are referring to the following first part:

Kudzu, an Asian vine that has grown rampantly in the southern United States, since it was introduced in the 1920s for thwarting soil erosion

This is not a run-on. A run-on sentence is when the sentence has two Independent clauses connected by a comma.

The first part does not have any Independent clause.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses types of clauses, their application and examples in significant detail. If someone is interested, PM me your email-id; I can mail the corresponding section.

Hi, can you please explain why we needed a that after Asian vine.. I had chosen E since it did not contain that why cant we go without a that in the sentence?
Can someone please help!!

Can anybody explain why in option B "for thwarting" is actually incorrect.
I was down to B and C and chose B.

(A) that has grown rampantly in the southern United States since introducing it in the 1920s to thwart - we do not need -ly here
(B) that has grown rampantly in the southern United States, since it was introduced in the 1920s for thwarting - same as A
(C) that has grown rampant in the southern United States since it was introduced in the 1920s to thwart - good
(D) growing rampant in the southern United States since introducing it in the 1920s for thwarting - it was introduced to do some task - we need preposition to not for
(E) growing rampantly in the southern United States, since it was introduced in the 1920s to thwart - same as A

I go with C

I think there is a run on sentence in option B

An Asian vine that has grown rampantly in the southern United States =>"Asian vine"is the subject and "has" is a verb and it expresses a complete thought.
Since it was introduced in the 1920 for thwarting soil erosion => "it" is the subject which refers to Kudzu and "was" is the verb and it also expresses a complete thought.

Even if we consider "Since" as a dependent marker and 2nd clause as dependent clause. What is the intent of the OG Explanations "The adverbial Clause Since it was introduced in the 1920 should not be set off from has grown rampantly"



Experts Please help. GMATNinja

(C) that has grown rampant in the southern United States since it was introduced in the 1920s to thwart

the vine has grown is the perfect verb to show us the timeline of the events. It has grown until now (X) and now we have the following consequences (Y)

(E) growing rampantly in the southern United States, since it was introduced in the 1920s to thwart

1) the vine (at most ) IS growing...........growing alone means zero as verb

2) The comma has no sense, thereafter does the IT refer to US ??

ridiculous, we are dealing with the vine, not the US. The US is just the place/country/land/continent where all the phenomenon is happening NOW

The first thing we are required to do in an SC question is figure out the structure of the sentence.

Main Clause: Kudzu ... has overrun many houses and countless acres of roadside.

We have an appositive next to Kudzu that renames it.
Kudzu, an Asian vine that ... soil erosion, has overrun many houses...

Highlighted is the appositive. Look at the options now.

(A) that has grown rampantly in the southern United States since introducing it in the 1920s to thwart

We need to use the passive 'since it was introduced in the 1920s...' because the action of 'introducing' was performed by someone else.

(B) that has grown rampantly in the southern United States, since it was introduced in the 1920s for thwarting

It is better to show intention using 'to thwart,' not 'for thwarting.'

'Since' is acting as a conjunction here but when it means 'from the time when,' we do not need to use a comma before it.
We would write it as 'It has grown rampantly since it was introduced in the 1920s.'

Also, it messes up the flow of the sentence. Where does the appositive end?

- Kudzu, an Asian vine that has grown rampantly in the southern United States, since it was introduced in the 1920s for thwarting soil erosion, has overrun many houses and countless acres of roadside.

or

- Kudzu, an Asian vine that has grown rampantly in the southern United States, since it was introduced in the 1920s for thwarting soil erosion, has overrun many houses and countless acres of roadside.

Which of the two is the appositive? Note that the appositive can easily be as shown in the second sentence. It can be re-written as this:

Since it was introduced in the 1920s for thwarting soil erosion, Kudzu, an Asian vine that has grown rampantly in the southern United States, has overrun many houses and countless acres of roadside.

Hence the 'comma' before 'since' brings in ambiguity. Has Kudzu overrun many houses since 1920s or has it grown rampantly since 1920s? Meaning is not clear.

(C) that has grown rampant in the southern United States since it was introduced in the 1920s to thwart

Corrects both the errors present in option (B).
Note that the use of 'rampant' is correct too.

'A has grown rampant' means 'A has become rampant' in which 'rampant' acts as an adjective.
'A has grown rampantly' means the growth has been rapid and hence, 'rampantly' acts as an adverb.

(D) growing rampant in the southern United States since introducing it in the 1920s for thwarting

We need to use the passive 'since it was introduced in the 1920s...' because the action of 'introducing' was performed by someone else.

(E) growing rampantly in the southern United States, since it was introduced in the 1920s to thwart

The main issue with this option is the comma before 'since' as explained above in option (B).

Answer (C)

In option C is the use of rampant correct ?
We use adverb to modify verb; here it is modifying grown .
For example how has the Kuzdu grown
Am i correct in my reasoning , if not please clarify.

Apart from the "for thwarting " error in option B,is the first part in option B is a run on as it was separated by a comma or if not is it right to put comma before since in the dependent clause?

GMATNinja-Thanks for the explanation-can you please explain how to eliminate A. Also, in my highlighted part of your post, did you mean 'rampantly' is an adjective or adverb?Also, you have mentioned rampant in the second sentence as well. Thanks

can anyone throw some light on the construct of option C & E
option C
(C)
Kudzu,
an Asian vine that has grown rampant in the southern United States since it was introduced in the 1920s to thwart soil erosion,
has overrun many houses and countless acres of roadside.

(E)
Kudzu,
an Asian vine growing rampantly in the southern United States,
since it was introduced in the 1920s to thwart soil erosion,
has overrun many houses and countless acres of roadside.

is the construction of C better is the only thing which makes it the right option or option E has some grammer/ly mistake?

Can you please explain why B is incorrect ?

Hi ran787, not sure if you read my post just above yours.

B uses for thwarting, whereas to thwart is preferable when intent needs to be depicted.

Also, B uses a comma before since, distorting the meaning.

In this question if I am not wrong
1) I think choice B and c are both run on sentences, don't we need a FANBOY conjunction or
a ; with the last part of the sentence starting with has
2) While in choice E 1st part is a modifier, followed by a subordinate clause, connected with an independent clause with verb has and its subject in the beginning .
Thanks in advance

Hi Kunal, a run-on sentence is when two Independent clauses are connected by a comma. In both B and C, there is only one Independent clause:

Kudzu has overrun many houses and countless acres of roadside.

Hi Smitc007, we can't just selectively do cherry picking of words, to concoct an Independent clause. has is not the verb for Asian vine. has is the verb for that.

So, basically that has grown rampantly in the southern United States is the dependent clause in this sentence.
