According to the passage, altruism is motivated more by social bonding, familiarity, and identification of belongingness to a group, and it has been shown that empathy or guilt does not play a central role. Therefore, the logical inference is that humans engage in altruism due to group identification, not due to empathy.
Step 1: Analyze the passage:
The passage clearly states that altruism is driven by group identification and not by empathy or guilt.
Step 2: Evaluate the options:
- Option (A): Incorrect, as the passage rejects the idea of altruism being driven by guilt.
- Option (B): Incorrect, as it contradicts the rejection of empathy as a motivator for altruism in the passage.
- Option (C): Correct, as it aligns with the information provided in the passage that altruism is motivated by group identification.
- Option (D): Incorrect, as it falsely attributes empathy as a reason for altruism.
Step 3: Conclusion:
The correct logical inference based on the passage is Option (C), where altruism is motivated by group identification, not empathy.
