Here's a breakdown:
Singular "it":
* When referring to society as a collective entity: "Society itself is constantly evolving."
* When emphasizing the collective nature: "The responsibility for this problem rests with it."
Plural "they/them":
* When referring to the individuals that make up society: "They are the ones who shape the future."
* When focusing on the diverse perspectives within society: "They have different opinions on this issue."
General guidelines:
* Focus on the intention: If you want to emphasize the collective nature of society, use "it." If you want to highlight the individual members, use "they."
* Consider the context: The specific sentence and surrounding text will provide clues on the best pronoun choice.
Ultimately, the best pronoun depends on the specific meaning you want to convey. There's no hard and fast rule, but understanding the nuances of "it" and "they" in this context can help you choose the most appropriate pronoun.
