Many pregnant women suffer from vitamin deficiency, but this is frequently not due to vitamin deficiency in their diets; most often it is because they have higher requirements for vitamins than do the rest of the population.
The best criticism of the reasoning in the statement above is that it
(A) fails to specify the percentage of pregnant women who suffer from vitamin deficiency
(B) gives insufficient information about why pregnant women have higher vitamin requirements than do other groups
(C) fails to employ the same reference group for both uses of the term "vitamin deficiency"
(D) provides insufficient information about the incidence of vitamin deficiency in other groups with high vitamin requirements
(E) uses "higher requirements" in an ambiguous manner

This a typical pattern you will see in CR arguments:
X > Y is because X has a higher value. The argument is saying that the difference is because Y could have a lower value too.
Here is an official question on a similar pattern: https://gmatclub.com/forum/in-countries ... 02322.html

We need to see an "issue" in this reasoning. What is the problem? What does it leave without clarifying? etc.
Note: This is not a type of question you would typically encounter on the GMAT. This more like an LSAT type.

% can be high or low . how does it matter? What if they had given us 37% or 47% - would it have changed things?
Many women suffer & for most THOSE women this is the reason.

Such questions will ask you to focus on argument structure and not the details mentioned. Focus on the WHATs and not the WHYs.
Why they have higher vitamin requirements is not needed - we can assume as they are pregnant they might need it.
carcass
To be honest this is not a flaw per se but true because it would help if there were more details provided.
We just have to assume it is because they are pregnant.
carcass
We are talking about pregnant women - "other" groups is out of scope.

Higher requirements could have also been a problem.
Now, let us look at C and E to compare which one is better.
In E when we say "higher requirement for Vitamins" - there is very little we can interpret it as. So I would still go with C.
Having said all this, I also think this is not very representative of the kind of questions you would see on the GMAT.

I did not understand the answer 1 bit. What does "the same reference group" mean - pregnant women group? What is "both" here refers to? - both sexes: men & women?
(C) fails to employ the same reference group for both uses of the term "vitamin deficiency"
(C) fails to employ the same reference group for both uses of the term "vitamin deficiency"
