Final answer:
The statement that drugs and alcohol are not permitted at a powwow is True, as these substances are not allowed in order to respect the cultural and spiritual significance of these events. Additionally, the temperance movement was related to urbanization and immigration, and the Proclamation of 1763 was a response to Pontiac's War.
Step-by-step explanation:
The use of drugs and alcohol are not permitted at a powwow. This statement is True. Powwows are social gatherings held by many different Native American communities that focus on cultural celebration, including dance, music, and food.
These events are family-friendly and centered around the preservation and celebration of indigenous culture, and as such, substances that could disrupt the respectful and spiritual nature of the event, such as drugs and alcohol, are typically not allowed.
Addressing the parts of the question regarding historical movements, the temperance movement did, in fact, stem from new social conditions such as increasing urbanization and immigration, making Choice A (True) correct.
Regarding the Iroquois Confederacy during the Revolutionary War, not all of the tribes maintained neutrality; therefore, Choice B (False) is accurate. Lastly, the Proclamation of 1763 was indeed enacted in part as a response to Pontiac's War, so this is True.
