What is the primary function of NORAD?

The primary function of NORAD, which stands for North American Aerospace Defense Command, is centered around air defense. It was established during the Cold War primarily to monitor and defend North American airspace against potential Soviet missile and air attacks. By integrating military capabilities from both Canada and the United States, NORAD plays a critical role in ensuring the security of North America through aerospace warning and control.

The organization operates radar and satellite systems to detect aircraft and missile threats, ensuring a coordinated response to protect the airspace. Its importance grew during the tensions of the Cold War, reflecting a collaborative approach to national security between the two nations involved.

The other choices do not align with the core mission of NORAD. Supporting trade negotiations pertains more to diplomatic efforts rather than military defense. Establishing international treaties involves processes led by governmental bodies concerning legal agreements between countries, which is not the focus of NORAD. Conducting scientific research involves pursuits that are typically outside the scope of NORAD's military-driven mission. Therefore, option B accurately encapsulates the essence of NORAD's primary function.
