Isn't this a run off sentence?
Clause1: The single-family house constructed by the Yana, a Native American people who lived in what is now northern California, was conical in shape

Clause2: its framework of poles overlaid with slabs of bark........

Please suggest



Hello ankursethi297,


Let me help you resolve your confusion about this official sentence. :-)

If two independent clauses are connected by just a comma, then the structure is called a run-off sentence.

However, this official sentence is not a run-off sentence because there is only one independent clause in this sentence the SV pair of which is The single family house... was.

Please note that the words overlaid and banked are verb-ed modifiers that modifies the preceding noun entity its framework of poles.

Generally, test takers mistake all the verb-ed words as modifiers. But that is not the case. To learn how to distinguish between the verb-ed modifier and the simple past tense that also ends in "ed", please review the article named ED FORMS - Verbs or Modifiers in the following link:

https://gmatclub.com/forum/ed-forms-verbs-or-modifiers-134691.html


Now let's talk about the structure its framework of poles overlaid with slabs of bark, either cedar or pine, and banked with dirt to a height of three to four feet. This tructure can very well be connected to a preceding clause by a comma because it is what we call at e-GMAT is a Noun + Noun Modifier in which its framework of poles = Noun and overlaid with slabs of bark, either cedar or pine, and banked with dirt to a height of three to four feet = Noun Modifiers.

We have a super detailed article named Noun + Noun Modifiers: The most "versatile" modifier that explains in excruciating details how these modifiers work with numerous official examples. You can review this article in the following link:

https://gmatclub.com/forum/noun-noun-modifiers-the-most-versatile-modifier-137292.html


So, this official sentence contains an independent clause that is connected to a modifier by a comma.


Hope this helps. :)
Thanks.
Shraddha

This one is pretty tricky, in my opinion. We’re mostly dealing with parallelism here, but it's not as straightforward as I’d like.

Quote:
A. banked with dirt to a height of


The underlined portion follows the word “and”, so we definitely need to think about parallelism. Here, the word that follows “and” is “banked.” In this case, "banked" is an adjective.

So what is “banked” parallel to? Well, “overlaid” is our nearest adjective, and that makes some sense: “its framework overlaid with poles… and banked with dirt to a height of three to four feet.” Not bad! That makes sense: the framework was banked with dirt. Keep (A).

Quote:
B. banked with dirt as high as that of

The only difference between (A) and (B) is the pronoun phrase, “that of.” “That” is a singular pronoun here, so it needs a singular antecedent. And we don’t have good candidates: “dirt” is the nearest singular noun, but that doesn’t make sense: “banked with dirt as high as the dirt of three to four feet.” Nope.

You can try the same thing with other singular nouns in the sentence (pine, cedar, bark, framework, house, etc.), but once you try to insert them into the sentence in place of “that”, you'll see that none of them make any logical sense. So (B) is gone.

Quote:
C. banked them with dirt to a height of

This is a little bit more subtle, but once “them” is added to the sentence, things get weird. The issue isn't necessarily that "them" is ambiguous (sure, there are a few different plural nouns that "them" could refer back to, but the nearest one, "slabs", is arguably OK). The real problem is that the parallelism doesn't really work. If "banked" is parallel to "overlaid", it doesn't make sense anymore: "its framework of poles... banked them with dirt"?!

OK, so what if "banked" is actually a verb, and it's parallel to "was"? That wouldn't make sense, either: "The single-family house constructed by the Yana... banked them with dirt." (C) is gone.

Quote:
D. was banked with dirt as high as


The verb phrase "was banked" follows "and", so it has to be parallel to some other verb phrase. "Was conical in shape" seems to be our best option, but that wouldn't make much sense, since it would imply that "The single-family house constructed by the Yana... was banked with dirt." And that's not quite right: the framework of poles was banked with dirt -- not the entire house. That's why it makes more sense to leave "banked" parallel to "overlaid", as in option (A). Eliminate (D).

Quote:
E. was banked with dirt as high as that of

(E) has the same pronoun error as (B), and the same parallelism/logic error as (D). So we’re left with (A).



Hi GMATNinja

I have a basic problem with this question. if we split the sentence and delete non-essential modifier we have
1)The single-family house constructed by the Yana was conical in shape,
2)its framework of poles overlaid with slabs of bark, either cedar or pine, and banked with dirt to a height of three to four feet.

two Ic cannot join each other with a comma
am I wrong?

Ah, I think I see where the confusion is coming from. The 2nd phrase ("its framework of poles overlaid with slabs of bark... and banked with dirt...") isn't an independent clause at all. "Overlaid" and "banked" are both modifiers here -- NOT verbs. So the entire phrase (beginning with "its framework") is actually just an absolute phrase, which is basically a type of noun (accompanied by tons of modifiers in this particular case) that's used to modify the preceding sentence.

In other words, the phrase that you have listed as #2 above is just giving us more information about phrase #1, and phrase #2 definitely is not an independent clause. Tricky!

how not to mistake "banked" for "was banked for"? I mean, how to know which parallels with which?

The best way to think about parallelism in this question is to react to each individual answer choice, and figure out how the parallelism works in each. Notice how I wrote the full explanation above: for each answer choice, I figured out what followed the parallelism trigger "and", and went from there. The parallelism turns out to be illogical in certain answer choices, but not in others.

Explanation is available here: https://gmatclub.com/forum/qotd-the-sin ... l#p1854761. Let me know if that doesn't clear it up.

I hope this helps!

The single-family house constructed by the Yana, a Native American people who lived in what is now northern California, was conical in shape, its framework of poles overlaid with slabs of bark, either cedar or pine, and banked with dirt to a height of three to four feet.

(A) banked with dirt to a height of
(B) banked with dirt as high as that of
(C) banked them with dirt to a height of
(D) was banked with dirt as high as
(E) was banked with dirt as high as that of

HI GMATNinja,

How in Option C banked them with dirt to a height of, "banked " is a verb but not an adjective?

Banked should modify poles

HI GMATNinja,

How in Option C banked them with dirt to a height of, "banked " is a verb but not an adjective?

Banked should modify poles

You're correct that "banked" SHOULD be an adjective that modifies "its framework of poles", and that's exactly what happens in the correct answer. In the explanation above for answer choice (C), I was just pointing out that it doesn't make sense for "banked" to be an adjective. And then I presented a hypothetical: what if "banked" is functioning as a verb instead? And it turns out that it can't do that, either. See above for more.

I hope this helps!

Wonderful explanations BY egmat and GMATNinja
I have one minor doubt in this question. What is the correct usage of " to a height of" and "as high as".
As per my understanding "as high as" should be followed by a definite attribute and not a range.
Is this correct ?

Ooh, interesting question, Raksat! I'd never thought about that, to be honest, but I think you're right: I don't think it makes sense to say "as high as three to four feet". If we're saying "as high as", then we should specify an absolute maximum value ("four feet", in this case), not a range. Good call.

To be fair, this isn't the sort of thing that I would bet my life on - you'll see far more serious errors in many GMAT answer choices, so I'd be conservative about it. But fundamentally, I think you're 100% spot-on. Nice observation.
