I came across a question that said something along the lines of "In a survey 60% of participants said yes and 40% said no" and the conclusion was "This shows more people believe yes than no" (Granted the question was much more nuanced and another flaw was present but thats besides the point of my question).
One of the ACs said "They draw a conclusion about the population in general based on only a sample of the population"
Even though I got this question correct because I saw the other flaw in the argument, the AC above was wrong which confused me because the explanation why it was wrong specifically said "there is nothing inherently flawed about drawing a conclusion from a sample. What would be flawed is relying on an unrepresentative sample".
Does this mean that if it said "We surveyed NYC, here are the results, therefore more people say yes than no" would be correct? or is it incorrect because it included information regarding the sample. In the question above there was no information regarding how the survey was conducted or who was a part of it but, they still made a generalization of the population from whatever sample they surveyed.
I initially got tripped up by this question because, like most questions that trip me up, I read too much into it.
B was ambiguous to me because:
1) how am I supposed to know that "Certain Medical Therapies" does not include Weight bearing exercise? As someone who has done a lot of Physical Therapy before (which is a medical therapy) weight bearing exercise can definitely be included thus supporting the argument.
2) Medical therapies that do not involve special diets does not inherently mean that one can not also be doing a special diet... Just like how it says both exercise and dieting are essential we wouldn't assume that these things are two things that go together... Would it be a wrong answer choice if it said "Certain weight-bering exercises that do not involve special diets can be effective means of preventing osteoporosis?"
The only reason why I got this correct is because A feels like it barely strengthens by barely eliminating a weakener, that being that "weightless exercise can also work" so weight bearing exercise is not essential?
