Final answer:
The NAR Code of Ethics requires REALTORS to be knowledgeable about international trade agreements, local housing market trends, and public opinion.
Step-by-step explanation:
The subject of this question is Social Studies, as it relates to political events, international agreements, and public opinion.
The NAR Code of Ethics preamble states that REALTORS should know about proposed and existing laws, public policies, government relations, and international trade agreements. This is important because international trade agreements can serve as a political counterweight to domestic special interests, preventing stronger protectionist measures.
REALTORS should also be knowledgeable about local housing market trends in order to provide accurate and up-to-date information to their clients. Additionally, they should understand public opinion in order to effectively participate in the democratic process and respect the rights, beliefs, and opinions of others.
