I want to know the answer to the following question:
Along with the USPS, what United States agency operates in the Marshall Islands?
All the background I'm provided with is that "Politically, the Marshall Islands is a presidential republic in free association with the United States, with the US providing defense, subsidies, and access to U.S. based agencies such as the FCC and the USPS.". Is that enough to answer the question?
Answer: yes
