@l0bstah_roll207 Your explanation makes a lot of sense! I can definitely see how E is not as strong as B. Even looking back at the question stem, this question is asking for the answer choice that "casts the MOST doubt on the validity of the evidence offered". I feel as though E can still weakly cast doubt on the validity of the evidence, but I think maybe I'm just confused about the explanation given under the answer choice for why E is wrong ("The argument is concerned with whether or not the polar bear was navigating, not how it was able to do so. The fact that polar bears often use smell is not relevant."). I just don't see how the sense of smell is completely irrelevant here.

But your reply is super helpful! Thank you!!

Same thing is happening to me :/

@KristenLee Ah that makes sense. Thank you! (and so real lol)

The stimulus says that navigation is defined as an animal's ability to find its way from unfamiliar territory to points familiar but BEYOND the immediate range of the animal's senses.

I feel like E weakens this argument by suggesting that polar bears are able to navigate back home within their immediate sense of smell to scent out familiar territory. This is not BEYOND their sense of smell, so therefore, aren't they using something other than navigation defined in the first sentence?

Can someone please help me understand how this AC is wrong?

For Q 27, I chose B because the author states in the last paragraph "That neither proposal was able to envision a system of education that was fully equal for women, and that neither was adopted into law even as such, bespeaks the immensity of the cultural and political obstacles to egalitarian education for women at the time."

The author points out in the passage that the proposals had incomplete views of equality which led me to think the author would most likely agree that they were fundamentally unethical. Is that wrong because assuming the author thinks the proposals were unethical is too strong an assumption?
