I will go with D,

Negate the statement :If children aren't aware of such injection or refrain from using it, then no way this will work to cure anemia.

Assumptions are unstated premise.
B is already stated in the argument .. You just need to paraphrase to get this .

I also marked B, but i am now convinced that it has to be D. An assumption is always an unstated premise.

why not C any idea?

i mean the conclusion is that "children who are suffering from anemia will be cured relatively simply through the use of such biochemical supplements"

so the assumption drawn can be that the natural foods which provide iron is not sufficient to reverse the condition.

If we use methods such as negation,

a diet rich in iron CAN improve the conditions of children suffering from anemia to the point that biochemical supplements would become unnecessary

that hurts the conclusion as well.

can somebody pls help.

So B can't be the answer if the assumption has already by stated?

+1 for D.

This question seems to be a variant of another similar question (which had adult persons instead of children). I do not like D for one reason : Even if children do not hear about the treatment, their parents might and eventually it is the parents that make the decision on the treatment.

Hey viks, I also use the negation technique when down to two very close choices. But one has to use this technique correctly in order to reap its benefits.

C: a diet rich in iron cannot improve the conditions of children suffering from anemia to the point that biochemical supplements would become unnecessary

Negation of C is: a diet rich in iron can sometimes improve the conditions of children suffering from anemia to the point that biochemical supplements would become unnecessary

Now you can see that negation of C doesn't hurt the conclusion in a decisive manner, as in some (or many) cases, biochemical supplements are still required.

I have read about negation technique in Powerscore - Critical reasoning bible, where it is beautifully explained. It states that negation is logical opposite and not polar opposite.

eg: Negation of wet is not wet, and not dry,
similarly negation of none is some , and not all

if you want a concise list of negation words, you can find them in Manhattan Gmat-CR book.
