Hello experts,
I was wondering if somebody could help me with answer choice B, specifically I want to make sure that I have understood why the second part (after the semi-colon) is not considered an independent one.

My analysis is that, "could prevent" could be considered the verb of "that" , so artificial reefs remain without a verb, thus the sentence is not an independent one.

That is exactly right, UNSTOPPABLE12. The subject of the second supposed clause, artificial "reefs," lacks a verb.

for example, artificial "reefs" of precisely shaped marine platforms that could prevent hurricanes from forming

From of on is an extended prepositional phrase, and the embedded that clause takes its own verb: [platforms] could prevent hurricanes from forming. Although it would make sense to say that the reefs could prevent the same, we would then be left with a that clause marker that would need to be deleted.

for example, artificial "reefs" of precisely shaped marine platforms that could prevent hurricanes from forming

Since you cannot negotiate the that, you know that the part after the semicolon is not an independent clause. Well done.

ANDREW first of all thank you for your prompt reply and the superb explanation ,

Just to make sure that I have completely understood the role of "that" in this sentence, so basically "that" in our case could refer to either "platforms" or "reefs" (of precisely shaped marine platforms is the modifier of reefs so "that" could modify reefs remotely) . If, that modifies "platform" then "could prevent" would be the verb of the sentence and the sentence would not be independent, but if somehow we knew that "that" modifies reefs (and in that case I suppose the existence of "that" would be optional , or even needs to be deleted to not make the sentence ambiguous ) then the sentence could be considered independent?

The that in the sentence at hand must refer to marine platforms; otherwise, there is an extraneous that in the sentence. But, of course, this creates a problem with semicolon usage: a phrase cannot be placed in the slot of a second independent clause in this construct. If the word in question were deleted, then yes, could prevent would reach back to artificial "reefs," and there would be no problem whatsoever. Since you have to go by what is on the screen, you know that that cannot be ignored, and that means that the second "independent clause" is actually incomplete, and the use of the semicolon is incorrect.

AndrewN will you please explain the non underlined portion of the sentence, I'm unable to understand it's meaning & find the verb also.

Thanks

Re: The emerging field of architectural climatology centers on t [#permalink]
The emerging field of architectural climatology centers on the potential of as-yet-undeveloped architecture and landscaping to alter, redirect, or dissipate weather systems; for instance, hurricanes prevented from forming by artificial "reefs" of precisely shaped marine platforms.

The field of climatology CENTERS on the potential of architecture to alter weather systems.

Well, GMATmona07, since a non-AndrewN felt the need to jump in and point out verbs, I will say on that point that centers is, in fact, the verb. As for the non-underlined portion, how about we see if we can break it down? I will include the word systems at the end for clarity.

The sentence describes a new field of study, architectural climatology, and what that field is interested in achieving: essentially, changing the weather. How so? By using architecture and landscaping techniques that have not yet been developed. That is the gist of the sentence, which is not the easiest to follow.

Thank you for thinking to ask, and good luck with your studies.
