Experts' Global Official Explanation:

Modifiers + Meaning + Redundancy/Awkwardness

Understanding the intended meaning is key to solving this question; the intended core meaning of this sentence is that tartaric acid is produced as a byproduct of wine fermentation, and a derivative of tartaric acid has proved to be a popular food additive.

• “who/whose/whom/which/where”, when preceded by a comma, refer to the noun just before the comma.
• “that” is used to provide the information needed to preserve the core meaning of the sentence, and the “comma + which” construction is used to provide extra information.

A. Trap. This answer choice incorrectly modifies “tartaric acid” with “which has proved to be a popular food additive…”, incorrectly implying that tartaric acid itself has proved to be a popular food additive in many parts of the world; the intended meaning is that tartaric acid is produced as a byproduct of wine fermentation, and a derivative of tartaric acid has proved to be a popular food additive; please remember, “who/whose/whom/which/where”, when preceded by a comma, refer to the noun just before the comma.
 
B. Trap. This answer choice alters the meaning of the sentence through the phrase “A derivative… of tartaric acid is produced…”; the construction of this phrase incorrectly implies that the derivative of tartaric acid is produced as a byproduct of wine fermentation; the intended meaning is that the tartaric acid itself is produced as a byproduct of wine fermentation.
 
C. Trap. This answer choice alters the meaning of the sentence through the phrase “A tartaric acid derivative… is produced”; the construction of this phrase incorrectly implies that the derivative of tartaric acid is produced as a byproduct of wine fermentation; the intended meaning is that the tartaric acid itself is produced as a byproduct of wine fermentation.
 
 D. Correct.  This answer choice correctly modifies “Tartaric acid” with “a derivative of which…” and “is produced as a result of…”, conveying the intended meaning- that tartaric acid is produced as a byproduct of wine fermentation and has a derivative that has proved to be a popular food additive. Further, Option D correctly uses the “comma + which phrase (“a derivative of which”)” construction to provide extra information.

E. This answer choice incorrectly uses the “comma + that” construction to provide extra information about a noun; please remember “that” is used to provide the information needed to preserve the core meaning of the sentence, and the “comma + which” construction is used to provide extra information.

D is the best answer choice.

nivivacious · Answer

(A) Incorrect : The phrase "a substance derived from tartaric acid" could refer to any number of substances and not necessarily the one that's a popular food additive.
(B) Incorrect : The placement of "of tartaric acid" at the end of the sentence makes it unclear what "a derivative" is referring to.
(C) Correct: This option is clear, concise, and grammatically correct. 
(D) Incorrect: While this is grammatically correct, this option changes the meaning of the sentence. It suggests that tartaric acid itself has a derivative that's a popular food additive rather than the derivative being a byproduct of wine fermentation.
(E) Incorrect: he word "that" at the end of the sentence has no antecedent making the sentence incomplete.

(A) A substance derived from tartaric acid, which has proved to be a popular food additive in many parts of the world,
- Original sentence. Correct.

(B) A derivative, which has proved to be a popular food additive in many parts of the world, of tartaric acid
- The use of "a derivative of tartaric acid" changes the meaning slightly, and it is not as concise as the original. Incorrect.

- Similar to (B), the use of "a tartaric acid derivative" is less concise than the original. Incorrect.

(D) Tartaric acid, a derivative of which has proved to be a popular food additive in many parts of the world,
- This construction is awkward and less direct than the original sentence. Incorrect.

(E) Tartaric acid has a derivative which has proved to be a popular food additive in many parts of the world, that
- The phrase "has a derivative which has proved" is wordy and less direct. Incorrect.

DongTan · Answer

(A) provides a clear and concise introduction to the subject matter. It states that there is a substance derived from tartaric acid, which has proven to be a popular food additive in many parts of the world. The phrase "which has proved to be a popular food additive in many parts of the world" provides additional information about the substance's popularity and its application in the food industry.

(B) rearranges the sentence structure but conveys a similar meaning. It states that there is a derivative of tartaric acid, which has proven to be a popular food additive in many parts of the world. The phrase "which has proved to be a popular food additive in many parts of the world" emphasizes the substance's popularity.

(C) is similar to option (B) but places more emphasis on the fact that the substance is a derivative of tartaric acid. The phrase "which has proved to be a popular food additive in many parts of the world" again highlights its popularity.

(D) begins with "Tartaric acid" and follows with a clause stating that a derivative of tartaric acid has proven to be a popular food additive. While grammatically correct, the phrasing is less clear and concise compared to the other options.

(E) is grammatically incorrect as it ends abruptly with the word "that." Additionally, the sentence structure is less effective in conveying the intended meaning.

In summary, option (A) provides the clearest and most coherent introduction to the substance derived from tartaric acid as a popular food additive. It effectively communicates the subject matter and its popularity in the food industry.

(A) A substance derived from tartaric acid, which has proved to be a popular food additive in many parts of the world,
Incorrect - The modifier "which has proved to be a popular food additive" suggests that tartaric acid itself has proved to be a popular food additive, rather than its derivative. 
(B) A derivative, which has proved to be a popular food additive in many parts of the world, of tartaric acid
- incorrect - A derivative of tartaric acid cannot be produced as a byproduct.
(C) A tartaric acid derivative, which has proved to be a popular food additive in many parts of the world,
incorrect - this option also suggests that a tartaric acid derivative is produced as a byproduct.
(D) Tartaric acid, a derivative of which has proved to be a popular food additive in many parts of the world,
Correct - this option effectively conveys the information without any ambiguity. Relative clause - a derivative of tartaric acid has proved to be a popular - correctly modifies tartaric acid. the main clause - tartaric acid is produced as a byproduct... is correct.

Answer D

paulkim46 · Answer

Answer: (C)

(A): Unnecessarily wordy ('a substance derived from...')
(B): Strange splitting of the subject ('derivative') and its precursor ("tartaric acid')
(C): Correct. Uses a succinct form of the subject clearly
(D): Subject is incorrect. The derivative is the subject, not tartaric acid itself
(E): Comma splice

andreagonzalez2k · Answer

If we eliminate "which has proved to be a popular food additive in many parts of the world" in all the answers we have:

(A) A substance derived from tartaric acid...is produced as a byproduct of wine fermentation
(B) A derivative of tartaric acid...is produced as a byproduct of wine fermentation
(C) A tartaric acid derivative...is produced as a byproduct of wine fermentation
(D) Tartaric acid...is produced as a byproduct of wine fermentation
 CORRECT 
(E) Tartaric acid has a derivative that...is produced as a byproduct of wine fermentation

What is produced as a byproduct of wine fermentation?: Tartaric acid, not the derivate product. So only D makes sense

IMO D

brp616 · Answer

IMO D

A - too wordy with ‘a susbstance derived’ and clumsy with the insertion of the second clause

B- a derivative and of tartaric acid are split in a funky way

C - this is grammatically correct but changes the meaning to imply only the derivative is formed in winemaking and not tartaric acid as a whole

D - correct grammar keeps everything intact

E - again, changes meaning and is a run on

I will go with option C

C option is correctly using "which" in the sentence. Now if you see in sentence "which" is describing about Tartaric acid that is wrong. If you omit comma to comma, C will be valid only.
