A. which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian,
B. officially known as the Flavian Amphitheater, begun in A.D. 69, during the reign of Vespasian, and

D. officially known as the Flavian Amphitheater and begun in A.D. 69, during the reign of Vespasian it
E. officially known as the Flavian Amphitheater, which was begun in A.D. 69, during the reign of Vespasian, and


The answer is C. But I am not able to discern as to how the part after ',and' is an Independent clause. The phrase 'was completed a decade later' does not have a subject. How is it a independent clause?

2 verbs can exist in a clause if they are connected with AND and OR. Then their subject will same
Otherwise SV pair must be equal to number of clauses in sentence.
Here 2nd clause must have SV pair...But subject is not there so to correct it either we can add a subject or we can connect 2 verbs with and if their subject is same...

Sent from my XT1068 using GMAT Club Forum mobile app

I get your point. But when you join two verbs you use only 'and' and when you join to independent clauses/thoughts you use ',and'. Please correct me if I am wrong. Thanks :)

C. Construction of the Roman Colosseum, which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, and was completed a decade later, during the reign of Titus, who opened the Colosseum with a one-hundred-day cycle of religious pageants, gladiatorial games, and spectacles.

One note is that the parallel- markers should join two equal things, either clauses, phrases or just words such as nouns etc, etc. In this case, "began in A.D. 69", a predicate is joined with "was completed " another predicate. So it is okay IMO. In addition, in two part symmetries, if the subject of the first part logically holds good for the second part too, then an ellipsis is permitted as parallel enough

A. which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, ----lacking conjunction between the two predicates

B. officially known as the Flavian Amphitheater, begun in A.D. 69, during the reign of Vespasian, and -----This is a fragment with the first part lacking a verb
C. which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, and --- Correct choice.

D. officially known as the Flavian Amphitheater and begun in A.D. 69, during the reign of Vespasian it --- The first part is a fragment and the second part is fused with the first part without a punctuation mark.

E. officially known as the Flavian Amphitheater, which was begun in A.D. 69, during the reign of Vespasian, and ----- The first part before 'and ' is a fragment.

Dear,
I read through all the explanations of this post and do agree that C is the most suitable answer. But as per chapter 10 of SC Manhattan (page 197), we do not use a comma before "and" to separate two verbs that have the same subject. Clearly, C uses "comma + and" to separate two verbs. Could you pls explain why? Thank you:D

Hi duckcanfly ,

Welcome to GMATClub. :)

I understand your point. But whenever we want to use any additional information within a sentence, we use two commas such that if you remove the stuff between those two commas, your sentence must hold the meaning.

Let's understand this in this sentence.

Construction of the Roman Colosseum, which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, and was completed a decade later, during the reign of Titus, who opened the Colosseum with a one-hundred-day cycle of religious pageants, gladiatorial games, and spectacles.

Did you find the meaning now? I have two phrases used here. I can eliminate them and conclude the final sentence as follows:

Construction of the Roman Colosseum began in A.D. 69 and was completed a decade later, during the reign of Titus, who opened the Colosseum with a one-hundred-day cycle of religious pageants, gladiatorial games, and spectacles.

I hope that makes sense. :)

(B) officially known as the Flavian Amphitheater, begun in A.D. 69, during the reign of Vespasian, and - B is a past participle -- so part before and is a fragment

(D) officially known as the Flavian Amphitheater and begun in A.D. 69, during the reign of Vespasian it - same as B and Construction of the RC during the reign of Vespasian it -- incorrect

In B and D , does "officially known as the Flavian Amphitheater" modify the entire noun phrase Construction of the Roman Colosseum or only the Roman Colosseum ?

It can refer to either. For example:

Big technology companies in Silicon Valley, once seen as XYZ...

Here the modifier could introduce information about either Silicon Valley
Big technology companies in Silicon Valley, once seen as a major hub for the aerospace industry...

or Big technology companies in Silicon Valley
Big technology companies in Silicon Valley, once seen as the best employers in the country...

However, this is perfectly acceptable in English, and even a which would have the same problem.

Hi,
There are two uses for comma and
1.to connect to independent clause
2.to connect list having more than two element
Both cases are not applicable for this case.
So how C is correct answer?

GMATNinja could you please explain how C is correct?
Thanks

Good question! The two scenarios you've listed are the most common acceptable uses of "comma + and," but virtually any "rule" involving commas is going to be complicated by modifiers.

Consider a silly example, "After deliberating for several hours, Ginger decided to invite both The Professor and Gilligan to her island rave." Notice that "and" is connecting two names or objects, and there's no good reason to use a comma here. So far so good.

But watch what happens if we insert some descriptive information about our aforementioned rave-goers. "After deliberating for several hours, Ginger decided to invite both the Professor, who was harvesting pineapple, and Gilligan, who was trying to cut open a pineapple with a plastic spoon, to her island rave." The phrase in red is non-essential information describing "The Professor," and so is set off by commas. So it's completely fine to end up with a "comma + and" construction here.

It's the exact same logic in (C): "began in A.D. 69, during the reign of Vespasian," is nonessential information describing "Flavian Amphitheater," and so it's set off by commas.

Takeaways: 1) commas can always be used to insert nonessential modifiers into a sentence, and 2) pineapple is tasty.

I hope that helps!

Problem with original sentence is coordinating conjunction which is missing,hence the option C is correct.
