The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, which, over 2,500 miles long and extending from northern Ecuador through Peru to southern Chili.

A. Underlined portion
B. Columbus was the Incan highway, over 2,500 miles in length, and extended
C. Columbus, the Incan highway, which was over 2,500 miles in length and extended
D. Columbus, the Incan highway, being over 2,500 miles in length, was extended
E. Columbus, the Incan Highway was over 2,500 miles long, extending

Ans shud be E.
Reason: 'extending ......' is a participle-modifier. In case of 'C' the sentence is not complete. The Incan highway should be described further in case of 'C'.
Let me know the OA.

IMO C

In all options other than A, B and E, don't you think that the Incan highway wrongly modifies Christopher Columbus?

I have my own doubts on E!

I support 'E'.

The greatest road system built in the Americas prior to the arrival of Christopher____from northern Ecuador through Peru to southern Chili.

Yes, '...extending from...' is required, That leaves us with 'A' and 'E', out of which 'E' is more grammatically sound.

I have my own doubts on E!

IMO,

First, the subject of the sentence is Incan highway, not Christopher columbus.

Second, the first clause that consists of Christopher columbus is the modifier because it starts by saying "The greatest system built...."

and the clause "extending...." is a modifier of the incan highway.

IMO E.

IMO E

I rejected all other options .
For C - the Incan highway is mentioned under commas that makes it non-essential
This is not the case as the Incan highway is subject and so it should not be mentioned under commas

The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, over 2,500 miles in length, and extended . Clearly B what's the OA?

Could anybody clarify why extending is better than extended? I always have problems with the participles...

The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, which, over 2,500 miles long and extending from northern Ecuador through Peru to southern Chili.

A. Columbus was the Incan highway, which, over 2,500 miles long and extending
Incorrect: The Incan highway mistakenly modifies Christopher Columbus.
B. Columbus was the Incan highway, over 2,500 miles in length, and extended
Incorrect: If you observe closely, the option is trying to convey that Christopher Columbus was The Incan....and extended (i.e Christ himself extended !!!)
C. Columbus, the Incan highway, which was over 2,500 miles in length and extended
Incorrect: This is a close shave. You need to notice that length and its extension are given equal importance.However, the length information is additional and should be seperated by commas.
D. Columbus, the Incan highway, being over 2,500 miles in length, was extended
Incorrect: Similar reasoning as B.
E. Columbus, the Incan Highway was over 2,500 miles long, extending
Correct: Here you will observe that extending is a participle modified which is correctly modifying The greatest Road system. The additional information the incan....long is seperated by commas.
I suppose..E fits the bill.

However I selected option C.

If you refer to OG, it will say that extending is something will last, extended is something happened then just finished. it won't last.

I go with B. Here are points:

1. When describing something in a long sentence, proper 'pause' is required. In this case, the word 'was' after the word Columbus serves the purpose. In no way, I see this 'was' affecting Columbus, as some of our friends argued.

2. In the sentence, there is no guarantee that the bridge STILL exists and hence, usage of 'extended' seems to be appropriate (for the given context).
After this bridge was constructed, for some reason it would have been destroyed and after that no bridge of length equal to or greater than that of this bridge would have been constructed.

3. Some might argue that length of the bridge is something that is fixed and hence 'extended' does not apply. But just as I said in point 2, for some reason, the bridge would have been altered. For e.g, when constructed it was 2000m long and after that modifications it became only 1000m long. Now, even if there exists some other bridge of length greater than 1000m, still the original statement holds good because I can argue that all that statement talking about is AT THE TIME of construction, but not currently available.

Hence for me B is correct.

In real life, points (2) & (3) that I mentioned above usually do not apply and hence 'extending' is correct. But GMAT is all about 'the given context' but not real life.

E is the correct answer as it is most precise one. The ans choices with "Which ' and "Extended" are incorrect.
