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

(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.

(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

(E) The Madagascar periwinkle, a derivative of which has proved useful in decreasing mortality among young leukemia patients,

[Reveal] Spoiler:
I understand that "which" following a comma, is supposed to refer to whatever is immediately preceding it. In this problem, "which" is preceded by the preposition "of" , that enables "which" to function correctly. I guess I got confused in the shuffle between answer choices (C) and (E), specifically noting the difference between "A Madagascar periwinkle derivative" and" The Madagascar periwinkle, a derivative..." In the initial sentence, I thought the focus was on "a substance derived from the Madagascar periwinkle", not the "The Madagascar periwinkle" itself (as in answer choice E). How were you able to make this distinction?

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?

Straight E.

Option A - A substance derived from X is cultivated in Y - Nonsensical construction
Option B - A derivative of X is cultivated in Y - Nonsensical construction
Option C - A [Adj.][Adj.] derivative is cultivated in Y - Nonsensical construction
Option D- Incorrect use of Present Perfect tense.
Option E - Madagascar Periwinkle cultivated in Y - Correct sensible construction.

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.

A simple way to look at this question is to ask:
What is cultivated in China?
Possible answer:
1) Periwinkle
2) Substance
Logical answer is Periwinkle.

I still don't like the question because there is some ambiguity. For example: Marijuana is a substance and Marijuana can be cultivated. Although the actual drug is a derivative of the plant, or so you can argue. :lol:
