Final answer:
Miller is referring to a trait inherited from previous generations.
Step-by-step explanation:
When Miller says, 'It is another trait we inherited from them,' he is referring to a characteristic or quality that has been passed down from previous generations. In this context, 'them' could refer to ancestors or a specific group of people.
For example, in a historical novel, 'them' could represent a specific family or ethnicity. In biology, 'them' could refer to parents passing down genetic traits to their children.
The phrase suggests that the trait being discussed has been inherited and potentially influences the individual or group being described.
