an old CR

[spoiler]this is the question from gmatclub. and i dont understand why the answer is D instead of C, can you guy take a look and it and explain me why?[/spoiler]

Recently, the research and development departments at major pharmaceutical companies have been experimenting with new injections that provide the boost in iron that anemic children need to reverse their condition. These companies have expressed confidence that children who are suffering from anemia will be cured relatively simply through the use of such biochemical supplements.

In concluding that the biochemical remedy being developed will have its desired effect, the pharmaceutical companies assume that

major pharmaceutical companies have the primary responsibility to cure childhood anemia
a low iron level in the body is the major factor influencing the incidence of anemia in children
a diet rich in iron cannot improve the conditions of children suffering from anemia to the point that biochemical supplements would become unnecessary
children afflicted with anemia will find out about and submit to injections that can reverse their conditions
the use of biochemical supplements is the safest way to cure anemia in children

A - irrelevant
B - Does not explain that increase in iron level will have the desired effect, which companies want, companies expect that after consuming their medicine children suffering from anemia will be cured. This statement is already assumed i.e. before preparing the medicine.
C - "relatively simply through the use of such biochemical supplements" explains that instead of consuming rich diets these supplements can cure anemia. C means the opposite of what is claimed.
D - If children do not find and take the supplements then they will not be cured and the companies belief wont be true.
E - out of scope.

Have a look at the Question stem. It asks the assumption of companies behind believing that the Injections will have desired effect. Thus D says that children find out about the remedy (the injection) and they will be ready to take the same.

If you negate the option D i.e. Children afflicted with anemia will NOT find out about and NOT submit to injections that can reverse their condition, then the argument that "Remedy will have desired effect" dies.

C looks very tempting and it could be an correct assumption if the question stem would not have asked explicitly about the Effects of Remedy. This could have been a valid assumption of the companies only irrespective of the usefulness of the remedy.

I think this a cause/ effect argument.

Such Biochemical supplement ( Implies: an injection that boosts iron) ----> relatively cure anemia

The argument assumes that there is no other alternative to cure anemia: A diet rich in iron (c)

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

BUT

D- says:children afflicted with anemia will find out about and submit to injections that can reverse their conditions.

If children with anemia don't get the injection, the desired effect will not be achieved.

Both C and D can be assumed!!!

B- a low iron level in the body is the major factor influencing the incidence of anemia in children: I think if B said the only factor instead of the major factor, it would be an assumption as well.

A and E are clearly irrelevant and I would have fallen for B :)

I am between C and D, but using the negation approach eliminates C. Does this approach always work when we are faced with tow choices that are both a possible answer?

Any feed back would be appreciated!
