Actually I don't like too much this questions because
1) I didnt find the answer (ok, forget this reason
2) the problem is not clear. Even with C it doesn't mean anything :
The argument points to the change in percent as proof that a greater proportion of women are adhering to a low-carb diet : This points to the inevitable conclusion that the proportion of women among people adhering to a low-carb diet has increased over the past decade
but with C you get :
The percentage of men between 18 and 24 years of age who followed a low-carb diet in 1992 and 2003
it said that this choice addresses the assumptions we've identified in the choices. If we know the percentage of men has not gone down then it is valid that the proportion of women increased.
First, it is wrong. If you take both percentage you can not find the percentage of women AMONG PEOPLE out of it. for example : 30% of men and 50% of women. We don't know the real values, how come you can get any idea. Maybe number are same but the population decrease, or maybe the number of women decrease so the % is up but it doesn't mean they represent less or more than before AMONG PEOPLE
Moreover, even if you know that both men and women, in %, who adher to low carb diet went UP, the trend may be in reality decreasing :
W 20/100 26/100
M 40/100 401/1000
20/200=10% of women among people
26/1100=2.6% of women among people
both rates were higher but it can't prove anything.
I understand that in CR you have to find the best answer among several, and that it doesn't mean this is the best possible answer at all, but I hope I will avoid this kind of problem because it is weird to answer something you know it is incorrect
But my Verbal is quite bad so maybe i am the only to react like this and maybe people here find the OA ok, if it's the case i will try to understand it more but please tell me if this answer is so logical
