Text 1: Evolutionary biologist Dr. Lisa Moore explains human brain evolution. "Our ancestors' survival required social cooperation," Moore writes. "Brains evolved to navigate complex social environments—detecting cheaters, forming alliances, managing reputations."
Text 2: Anthropologist Dr. James Kim studies non-social cognitive demands. "Environmental challenges—tracking seasons, locating food, creating tools—also shaped cognitive evolution," Kim argues. "Social intelligence wasn't the only selective pressure. Ecological problem-solving contributed substantially."
What does Kim suggest about Moore's evolutionary explanation?
That human brains didn't actually evolve
That social factors may be overemphasized relative to other cognitive demands
That ancestors never cooperated socially
That ecological challenges are irrelevant to survival
Correct Answer: B
Choice B is the correct answer. Moore focuses on social demands. Kim adds ecological challenges as "substantial" contributors, suggesting Moore's social emphasis may be incomplete—not wrong, but overemphasized.
- Evidence: Kim: "Social intelligence wasn't the only selective pressure."
- Reasoning: Multiple factors drove cognitive evolution.
- Conclusion: Moore's social focus may underestimate other factors.
Choice A is incorrect because Kim accepts brain evolution. Choice C is incorrect because Kim doesn't deny social cooperation. Choice D is incorrect because Kim emphasizes ecological relevance.
