@erojas and @jamesio, we have the answer as B in our system. Is there a mistake somewhere?Ro on September 25, 2018

can you please explain this question? Why is B the answer? I had Eon November 6, 2018

Yeah, why is it B? I had E tooJacob on November 7, 2018

Answer B is correct. The question stem lets us know that we are looking for why the argumentâ€™s reasoning is most vulnerable to criticism.What is the argument actually saying? We know that it is making a claim about Mayan civilizationâ€™s grasp on math â€” â€œnot onlyâ€ about Mayan astronomers, but about the Mayan people â€œin general.â€

But the evidence we get for the claim about Mayan people â€œin generalâ€ is about the writings of the Mayan religious scribes, which exhibited a high degree of mathematical competence. That doesnâ€™t seem like a correlation/causation error (answer E), as the argument isnâ€™t using the fact of Mayan religious scribesâ€™ abilities to say anything about what is causing the Mayan people â€œin generalâ€ to have good math skills.

Instead the reasoning is flawed because the Mayan religious scribes are probably a sample that is unrepresentative of the general population â€” these are religious scribes! Not ordinary people!

That is why B is the right answer. I hope that helps!
