Would go with A.

In B- comma modifications are misplaced twisting the meaning of original sentence

In C- “”The amount of plastic , “modifier” , combined with their own onservations “” is senseless aa you cannot combine the amount of plastic with observations.

In D- “and” with their own observations, this “and” does not go with the “By combining”

In E- has same problem as C.

A. By combining the amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, with their own observations, researchers from Greenpeace were able

B. A known quantity from previous researchers’ work, the amount of plastic entering the ocean in each country, combined with their own observations, allowed researchers from Greenpeace to be able - as far as i know, GMAT doesn't like such passive structures: it should be "allowed researches to do something", not "allowed to be able to do something"

C. The amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, combined with their own observations, allowed researchers from Greenpeace to be able same as in B - passive

D. By combining the amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, and with their own observations, researchers from Greenpeace were able - combining the amount ... AND with their observations

E. The amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, and combined with their own observations, allowed researchers from Greenpeace to - the amount ... AND combined with their observations

A. By combining the amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, with their own observations, researchers from Greenpeace were able - correct choice

B. A known quantity from previous researchers’ work, the amount of plastic entering the ocean in each country, combined with their own observations, allowed researchers from Greenpeace to be able - SV/Modifier error

C. The amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, combined with their own observations, allowed researchers from Greenpeace to be able - SV/Modifier error

D. By combining the amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, and with their own observations, researchers from Greenpeace were able - correct idiom is 'by combining X with Y'

E. The amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, and combined with their own observations, allowed researchers from Greenpeace to - SV/Modifier error

VERITAS PREP OFFICIAL SOLUTION:




This complex sentence is mainly testing the location of several different types of modifiers. (A) and (D) start with the prepositional phrase “by combining” while (B), (C), and (E) start with noun phrases. Starting with the “By combining” in (A) and (D), you see that “a known quantity from previous researchers’ work” is an appositive modifier giving extra information about the amount of plastic – it is correctly used, so get rid of it using slash-and-burn to look at the rest of the sentence. (A) correctly says “By combining this amount WITH their own observations, researchers were able…” and (D) incorrectly says “By combining this amount AND WITH their own observations, researchers were able…” . (A) appears to be the correct answer but you must first check (B), (C), and (E).

All of these jumble up the order of modifiers to create meaning and/or structural problems: (B), (C) and (E) create illogical predication as the amount of plastic did not allow the researchers to do anything – it was their act of combining the two data figures that allowed them to estimate. (E) also has the incorrect “and combined with”. Therefore, the correct answer is (A).

How can researchers combine amount of plastic with their own observations? The very odd question by Veritas.

https://www.nytimes.com/2018/01/25/science/plastic-coral-reefs.html

In their survey of about 12,000 square meters of reef, the researchers noticed that countries that are known to have particularly poor methods of dealing with plastic pollution had the most plastic on corals. By combining the amount of plastic entering the ocean in each country, a known quantity from previous researchers’ work, with their own observations, they were able to estimate how much plastic was likely on reefs in 15 different nations in the Asia-Pacific region.

NYT has many doubtful constructions that would not be acceptable on GMAT. Example:

Gabriel’s family,who live in rural southwestern Pennsylvania,have private health insurance but rely on Medicaid to pay for treatments for Abby that her insurance doesn’t cover

https://www.nytimes.com/2018/07/02/opinion/women-democratic-party-grassroots-trump.html

In 1 sentance 2 discrepancies with GMAT rules.

About 5 million acres in the United States have been invaded by leafy spurge, a herbaceous plant from Eurasia with milky sap that gives mouth sores to cattle, displacing grasses and other cattle food and rendering rangeland worthless.

(A) States have been invaded by leafy spurge, a herbaceous plant from Eurasia with milky sap that gives mouth sores to cattle, displacing grasses and other cattle food and rendering

(B) States have been invaded by leafy spurge, a herbaceous plant from Eurasia, with milky sap, that gives mouth sores to cattle and displaces grasses and other cattle food, rendering

(D) States, having been invaded by leafy spurge, a herbaceous plant from Eurasia with milky sap that gives mouth sores to cattle, displaces grasses and other cattle food, and renders

https://www.nytimes.com/1998/06/09/science/rootin-shootin-raiders-conquer-native-ground.html

LEAFY SPURGE. About five million acres in 26 states, including New York, have been invaded by leafy spurge, an herbaceous plant from Eurasia with milky sap that gives mouth sores to cattle and displaces grasses and other cattle food, rendering range land worthless. Ranchers tried putting sheep on spurge-infested range. Although they eat the plant, they do not kill it and there is not enough of a market for sheep wool and meat. So about 13 insects have been imported to help control it. Dr. Neal Spencer, an entomologist at a Department of Agriculture research laboratory in Sidney, Mont., said flea beetles had been most effective. The adult beetles feed on the leaves and their larvae mine the roots.

You have just right now proved my point of view, because GMAT marks the original version (option A) of text in NYT as incorrect, introducing comma set for non-essential modifier "with milky sap" to bring clarity (option B - correct). :-)

GMAT takes texts from NYT and modifies them, if the text does not follow GMAT's vision of what is clarity and grammar standards.

Tip: If you want to be acquainted with the real GMAT vision on SC, read WSJ (even TheEconomist sucks vs WSJ). I dont know why GMAT doesn't take text from WSJ, probably because of copyright issues.

Doesn't it means that researchers are doing the action of combining the amount of plastic with their own observations?
Hence they are combining a statistical entity (amount) with their own observations data. Hence A is correct.
