Generally, the modifier, "quadrupling the production of its next biggest competitors" gives room to contend that Chile adopted the policies to enhance and quadruple the production of its competitors. The author probably meant to say 'over' its competitors' but stated 'of' instead.

Generally, COMMA + VERBing serves to modify the agent of the nearest preceding action.
The OA implies the following:
Chile...has produced more copper than has any other country, quadrupling the production of its next biggest competitors.
Here, COMMA + quadrupling seems to modify any other country -- the agent of the nearest preceding action in blue -- implying that ANY OTHER COUNTRY is QUADRUPLING the production of ITS COMPETITORS.
This meaning is nonsensical.

None of the answer choices is viable.
I would ignore this SC.
What is the source?

Since the 1980s, when Chile adopted free market economic policies that attracted significant investment, copper has been the country’s top commodity, quadrupling the production of its next biggest competitors, China and the United States.

A. Since the 1980s, when Chile adopted free market economic policies that attracted significant investment, copper has been the country’s top commodity, --> subject/doer of "quadrupling" should make sense i.e. it should be "Chile"
B. Since Chile adopted free market economic policies in the 1980s that attracted significant economic investment, it has produced more copper than any country, --> "Chile has produced more copper than any country" : compare copper w/ country doesn't make sense
C. Chile attracted significant economic investment in the 1980s by adopting free market economic policies, and ever since then, it has produced more copper than has any other country, --> correct
D. Copper has been Chile’s top commodity since the 1980s, when free market economic policies attracted significant investment,
E. After Chile adopted free market economic policies that attracted significant economic investment in the 1980s, it has produced more than any other country, --> same as B

In order to solve the question keep an eye on the comparisons and comma subject rule.
1. than any country is wrong as it includes chile as well so any other country
2. the main subject of the sentence should be chile as the non uderlined adjective phrase quadrupling.. should modify chile not copper.

A. Incorrect subject is copper.
B. any country.. Incorrect
C. Seems OK keep it
D.Subject Change Incorrect.
E.it has produced more than any other country ...wrong comparison verb missing in the any other country (does) Incorrect.

E. After Chile adopted free market economic policies that attracted significant economic investment in the 1980s, it has produced more than any other country,


A. It seems like after Chile adopted new policies copper has become a top commodity - it sounds a bit strange.
But the most important part is that in this option "quadrupling" that comes afrter an underlined part is not in the correct place. And it can not be true, because it is not underlined.
Quadrupling is about producing of copper, not about copper itself. So out.

B. First of all lets mention the usual GMAT trap: "any country" is wrong, because it contains Chile as well and production pf copper in Chile can not quadruple production of copper in Chile.
We have to use such construction: "any other country".
Moreover. "it has produced more copper than any country" - it is a wrong comparison. We can not compare production of copper with country. Out.

D. I would say, here is the same problem as in A. Out.

E. Again. Can not compare production with country. Out.

C. Chile attracted significant economic investment in the 1980s by adopting free market economic policies, and ever since then, it has produced more copper than has any other country
All mistakes mentioned above are avoided. Sounds good.

Original: Since the 1980s, when Chile adopted free market economic policies that attracted significant investment, copper has been the country’s top commodity, quadrupling the production of its next biggest competitors, China and the United States.

Correct: C. Chile attracted significant economic investment in the 1980s by adopting free market economic policies, and ever since then, it has produced more copper than has any other country,

Hasn't the meaning of the first part of the sentence changed from the original? I interpreted the original as saying Chile adopted free market economic policies in 1980s and "significant investment" came after (could be in 1980s, could be in 1990s - it was not specified).

The answer flagged as correct pegged "significant investment" as coming in the 1980s, which seems different to me. What am I missing here?

Hello,
I am a bit confused with the option C because nowhere is it stated that Chile has become the largest producer in the original sentence, so how do we arrive at this?
Thanks
