Many pregnant women suffer from vitamin deficiency, but this

Question

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 the pregnant women who suffer from vitamin deficiency
b) give 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 â€œvitamin deficiencyâ€

rthothad · Answer

I will go with 'B'
The reasoning is 'they have higher requirements for vitamins than do the rest of the population' 
a) Not relevant.
c) Not relevant - "vitamin deficiency" is referred in the conclusion and not in the reasoning.
d) Nothing is mentioned in the passage about other groups having higher vitamin requirements - Out of context.
e) Comes close but I am not sure about the ambiguity part.

The OA from the answer key is C. I have been thinking about this too. I have been doing many CR and noticed that some of the answers are very subtle. 

I will TRY to come up with some rationalization on this OA.

I choose C because in the latter part of the sentence, (after 'but') vitamin deficiency lacks a proper reference to the subject (pregnant women). The word 'their' after the second vitamin deficiency could mean preganant or the rest of the population.

I discarded B since the word 'pregnant' implies a higher need for nutrients and thus does not need additional clarification as to why preg. women need more vitamins. I thought it was logical to assume that preg. women need more vitamins.

tough question.

I kinda disagree, look at the sentence below alone.

Many  pregnant women  suffer from vitamin deficiency, but this is frequently not due to vitamin deficiency in  their  diets.

Grammatically, "their" must refer to "pregnant women" no matter what.
