Guys,
I am confused on how GMAT uses comma in some sentences.

e.g
1. OG 12 - Question 61

Rivaling the pyramids of Egypt or even the ancient
cities of the Maya as an achievement, the army of
terra-cotta warriors created to protect Qin Shi Huang,
China’s fi rst emperor, in his afterlife is more than
2,000 years old and took 700,000 artisans more than
36 years to complete.

in the above sentence, "in his afterlife" is a telling something about China's first emperor. This makes sense, but you have "is more than..." that follows "in his afterlife". I thought, this("is more than") is part of the "in his afterlife" and tells something about the emperor. I know an emperor can never be 2000 yrs old but still i did not think that "is more than" tells something about the main subject i.e the army

2. example - OG 12 - Question 28

Building on civilizations that preceded them in coastal Peru, the
Mochica developed their own elaborate society,
based on cultivating such crops like corn and
beans, the harvesting of fish and shellfish, and exploiting
other wild
and domestic resources.

In this example, why doe we have a comma before "based" ?

Appreciate if some one can explain the above question and how does comma work in GMAT ?

If you have any questions

2. example - OG 12 - Question 28

"Building on civilizations that preceded them in coastal Peru" is modifying "the Mochica"

and underlined part " based on cultivating such crops like corn and
beans, the harvesting of fish and shellfish, and exploiting
other wild
and domestic resources." is modifying "society"

Note: If modifier is not essential then put comma between non-essential modifier and its noun.

[quote="ms"]Guys,

I thought, this("is more than") is part of the "in his afterlife" and tells something about the emperor. I know an emperor can never be 2000 yrs old but still i did not think that "is more than" tells something about the main subject i.e the army

"The China's first emperor" modifies QSH. detect by the open and close comma (in red) which is the appositive modifier (if i do not use the word wrong). It is simply N. modify N. (QSR=the China's first emperor)

So if you cut out the middleman, it will be "the army of terra-cotta warriors [created to protect Qin Shi Huang(,
China’s first emperor,) in his afterlife] is more than 2,000 years old and took 700,000 artisans more than 36 years to complete".
"[created..]" modifies the army of TCW
"in his afterlife.." is adverbial clause and modifies to protect

2. example - OG 12 - Question 28

Building on civilizations that preceded them in coastal Peru, the
Mochica developed their own elaborate society,
based on cultivating such crops like corn and
beans, the harvesting of fish and shellfish, and exploiting
other wild
and domestic resources.

On this one, i agree with swatirprv.
