Correct answer: insight

Explanation: The word 'insight' is appropriate here as it refers to the ability to gain a deep understanding of a person or thing, which is what Mills provided regarding society's daily lives. It fits both grammatically and contextually, as it aligns with the idea of understanding complex social dynamics.

Correct answer: respectively

Explanation: The word 'respectively' is used to indicate that two items correspond to two other items in the same order. In this context, it correctly links 'troubles' to 'biography' and 'issues' to 'history', maintaining clarity and coherence in the sentence structure.

Meaning: 'Respectively' means in the order given, which clarifies the relationship between the terms 'troubles' and 'issues' with 'biography' and 'history'.

Wrong options:

Explanation: The word 'realize' fits grammatically and contextually as it means to become fully aware of something as a fact, which aligns with the idea of understanding the relationship between personal experiences and larger societal contexts.

Meaning: 'Realize' means to become aware of or understand something clearly, particularly in relation to personal and societal connections.
