Question

what does a linkage institution help people do?
○ understand their family history
○ become disinterested in local politics
○ interact with their government
○ stay current on scientific developments

Explanation:

Linkage institutions (like political parties, interest groups, media) connect citizens to government. "Understand family history" is about genealogy/history, not linkage. "Disinterested in local politics" is opposite of what linkage does (they engage people). "Scientific developments" is natural science/tech, not political linkage. So the correct option is the one about interacting with government.

Answer:

C. interact with their government
