Final answer:
Gun salutes are rendered on special occasions such as Independence Day, the President's Birthday, and the arrival of a foreign dignitary, but not at sunset. In foreign policy, emergency spending measures are not as sharply focused as other options such as presidential summits, military uses of force, or international agreements.
Step-by-step explanation:
Gun salutes are a traditional honor given for various ceremonial purposes within the military and during state functions. These salutes are typically rendered on special occasions, such as Independence Day, the President's Birthday, and the arrival of a foreign dignitary. However, a gun salute is not customary at sunset, which is more associated with the lowering of the flag, or retreat ceremony, in military tradition.
Comparably, in terms of foreign policy outputs, emergency spending measures are not as sharply focused as the other options provided. While presidential summits, military uses of force, and international agreements are direct actions that relate distinctly to foreign policy, emergency spending measures, while they can be related to foreign policy, are more broadly applicable to various aspects of government spending and not exclusively focused on international relations.
