Reading the passage

B spends its second paragraph on monogamous families, then asks whether gene propagation really explains them. That's the example I expect. We need the behavior receiving a questionable explanation, not just any fact mentioned while presenting that explanation.

Working the answers

  • A

    Small kin-based communities belong to A's account of altruism. They aren't B's example of a behavior receiving a doubtful explanation.

  • B

    Slow maturation is part of the information used to explain monogamous families. B isn't questioning an explanation of why children mature slowly. This choice confuses a fact used in the reasoning with the behavior being explained.

  • C
    Correct

    B describes the proposed explanation for monogamy in humans and asks, “Are they right?” Its answer, “Maybe yes, maybe no,” introduces the concern that other interests might also explain that behavior. That's precisely an explanation B treats as questionable.

  • D

    B may think evolutionary psychologists misidentify people's interests. But it doesn't offer their misinterpretation as a human characteristic for which those psychologists propose an evolutionary explanation.

  • E

    Caring for something for its own sake is part of B's alternative account of motivation. It isn't the example of a behavior the evolutionary psychologists are described as explaining here.
