First of all start from what is un-underlined. What is cultivated? Obliviously a plant, not its derivative nor a substance derived from the plant. This takes us straight to Choice E. Choice D, as such will have two verbs for a single subject and hence is a run-on and wrong. Does it help?

OA is E. Please explain why? I go with C

C is wrong because it conveys that the madagascar periwinkle derivative itself is cultivated. Madagascar periwinkle is cultivated, not its derivative

A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients, is cultivated in China as part of a program to integrate traditional herbal medicine into a contemporary system of health care.

(A) A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients,
(B) A derivative, which has proved useful in decreasing mortality among young leukemia patients, of the Madagascar periwinkle,
(C) A Madagascar periwinkle derivative, which has proved useful in decreasing mortality among young leukemia patients,
(D) The Madagascar periwinkle has a derivative which has proved useful in decreasing mortality among young leukemia patients, that
(E) The Madagascar periwinkle, a derivative of which has proved useful in decreasing mortality among young leukemia patients

OA is E. Please explain why? I go with C

The Madagascar periwinkle is cultivated in China as part of a program to integrate traditional herbal medicine into a contemporary system of health care but not the The derivative of periwinkle .
In "C" the meaning goes as follow :

The derivative of Madagascar periwinkle is cultivated in China as part of a program to integrate traditional herbal medicine into a contemporary system of health care.

Which is why the same option is ruled out [:)] ..

The answer should be "E" ..hope this will help.

Look at the non-underlined part for clues:

,_______________ is cultivated in China as part => From this usage it is clear that we need a subject for the action verb "is cultivated "(what is cultivated) . Definitely the substance is not cultivated, neither is the derivative cultivated => A, B and C out. D is just absurd as that is used to modify patients ...

E is the obvious winner.

If there were no "is" in the original sentence, the usage would be correct

The substance derived from grass cultivated in china => here cultivated in china is modifying the noun (grass).

But you cannot say,

The substance derived from grass is cultivated in china => Incorrect. This says "The substance derived from grass" is actually cultivated => something that is absolutely absurd. The substance is not cultivated, the grass is cultivated.

20. A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients, is cultivated in China as part of a program to integrate traditional herbal medicine into a contemporary system of health care.

I believe understanding the meaning is crucial while solving this question..I cracked it under 1 minute...
A substance cannot be cultivated, thus, we need to look for an answer choice that would tell us that a tree or smth that can BE cultivated is actually cultivated.
only 1 answer choice is correctly written.

a. A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients,
meaning error - a substance cannot be cultivated

b. A derivative, which has proved useful in decreasing mortality among young leukemia patients, of the Madagascar periwinkle
same error. + a derivative is useful - but we need to specify what kind of derivative before the long modifier..

c. A Madagascar periwinkle derivative, which has proved useful in decreasing mortality among young leukemia patients
same meaning error.

d. The Madagascar periwinkle has a derivative which has proved useful in decreasing
strange one..I believe not written as needed.. nonetheless we don't have a subject for the verb is cultivated, because the periwinkle has a verb - has, which is not properly connected to the other verb.

e. The Madagascar periwinkle, a derivative of which has proved useful in decreasing mortality among young leukemia patients,
good.

Hi All,

I typically use the standard 3 step approach suggested by egmat :

Meaning analysis:

A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients, is cultivated in China as part of a program to integrate traditional herbal medicine into a contemporary system of health care.

Imagine that the wheat plant is cultivated and the flour is useful for a treatment. Now flour is a derivative of the plant, can the flour be cultivated ?

Now based on this analogy lets understand the original question:

What is useful in decreasing mortality ?
The derivative

What is cultivated ?

Error Analysis:

1. "from the madagascar periwinkle, which has proved useful" --> "Which" always refer to the immediate preceding noun which in this case is the periwinkle. As per our meaning analysis "the derivative" is what is useful
2. " A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients, is cultivated " --> The striked out portion is providing more information about periwinkle and should be ignored to understand what is cultivated. A substance derived, ..., is cultivated --> This is incorrect as per our analysis

(A) A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients,--> As pointed out in the error analysis

(B) A derivative, which has proved useful in decreasing mortality among young leukemia patients, of the Madagascar periwinkle, --> A Derivative,..., is cultivated --> Incorrect as pointed in the error analysis.

(C) A Madagascar periwinkle derivative, which has proved useful in decreasing mortality among young leukemia patients,--> Derivative is cultivated--> As pointed in the error analysis, this distorts the meaning

(D) The Madagascar periwinkle has a derivative which has proved useful in decreasing mortality among young leukemia patients, that --> "that" has a hanging precedent noun. In this statement "that" can refer to patients

(E) The Madagascar periwinkle, a derivative of which has proved useful in decreasing mortality among young leukemia patients, --> This correctly addresses the mistakes.

I hope this is helpful !

This concept is based on the understanding of Madagascar periwinkle.

As the sentence talks about some derivative (or substance) - it is logical that we cannot cultivate a substance.

Hence, logically "is cultivated" refers to "Madagascar periwinkle" - Hence - THe only option that gives us this choice is E

Option D-Wrong construction

Option E-correct-Modifier between the commas correctly modifying Periwinkle, also if we ignore the statement between the comma, the sentence comes out to be Madagascar periwinkle is cultivated in china

The statement explains what is cultivated is Madagascar periwinkle and not its derivative.
Hence, A can be eliminated as it implies that Madagascar periwinkle has proven to be useful.
B and C are incorrect as they suggest that the derivative is cultivated.
D can be eliminated due to incorrect usage of ‘that’.
E is the best choice here. Hence (e).

this question is fairly easy if one knows what is to be cultivated. if we know this, we can eliminate choices a, b, and c. between d and e, e is the obvious answer.

Now i have a question. how/why would i know that a derivative of a plant, which technically will be/is a plant cannot be cultivated?

Well, all of us can agree with the fact that a substance, as the name suggests, technically cannot be cultivated so A is out straightaway.

would gmat really test us on these type of concepts? GMATNinja egmat daagh ....I don't think so.

what i just said is my personal opinion. I am not a teacher/tutor. i am just a curious student.

This is said to be a 700-level question. Why wouldn't GMAT test this? If it is just a technical issue, and if you believe it is an easy one, some statistics in this thread also claim that the difficulty level is 85%hard and that 57% of the people responded incorrectly. I feel it must have been tested by GMAT sometime in the past. All the same, you deserve congratulations for your deep involvement in the subject.
