第二段提了不同cultures中，universal norms (非特指因纽特人）are rooted in basic human needs and ..., 然后讲了social instincts在norms形成中的重要性。没有一点提及tradition

第一段最后一句life in xxxx is so demanding讲的就是living condition，A选项如果有问题是drive这个词而不是living。

With life in the unforgiving Northern Cariada being so demanding, the Inuit's practical approach to morality made good sense.


第二段全文贴上来，没看到那一句是讲social tradition的。
The similarity of moral virtues across cultures is striking, even though the relative ranking of the virtues may vary with a social group's history and environment. Typically, cruelty and cheating are discouraged, while cooperation, humbleness and courage are praised. These universal norms far pre-date the concept of any moralising religion or written law. Instead, they are rooted in the similarity of basic human needs and our shared mechanisms for learning and problem solving. Our social instincts（本能）include the intense desire to belong. The approval of others is rewarding, while their disapproval is strongly disliked. These social emotions prepare our brains to shape our behaviour according to the norms and values of our family and our community. More generally, social instincts motivate us to learn how to behave in a socially complex world.
