Sentence Correction

Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, which would rob the oysters there of their flavor, and to make them decrease in size, less distinctive, and less in demand.

A. which would rob the oysters there of their flavor, and to make them decrease in size
B. and it would rob the oysters there of their flavor, make them smaller
C. and rob the oysters there of their flavor, making them decrease in size
D. robbing the oysters there of their flavor and making them smaller
E. robbing the oysters there of their flavor, and making them decrease in size
[spoiler]Ans:D[/spoiler]

IMO D ....

robbing the oysters there of their flavor and making them smaller correctly modifies alter the saline content of Apalachicola Bay

this good question is typical of gmat one, basic and hard.

gmat want us to write grammatically and logically. we check grammar first

"which"in A has no logic referent

"made them" in B is not coordinated. we need "and". this error is easy to realize. that is why I tell you check grammar minor error first.

"it"in B is redandant. we do not need "it"

check meaning logic

when you see split between "and do" and "comma+doing" ask yourself what meaning is more logic. 'and do" show an action separate and dependent from previous action

"comma+doing" shows an action which is created by the previous action or is happening simultaneously with previous action. in other words, "comma+doing" modify entire previous clause

process of considering which meaning is more logic is hard for us. This is typical of gmat test. who can realize the logic is successful. you need to practice more to react to no-logic things than to react to ungrammatical element. Quantitative section test numerical logic and verbal section tests non-numerical logic.

It is more logic to mean that ALTERING CONTENT create ROBING. D and E are left.

"decrease in size" is wordier than "smaller". D is left

you can realize that to increase speed and confidence, allway check grammar first. Second, check meaning logic. Third, check style or more simply, check wordiness. The logic of this order is that gmat want a sentence grammatical and logic before a sentence consice.
