Final answer:
The statement that all of the tribes in the Iroquois Confederacy remained neutral during the Revolutionary War is false. An increased sense of common identity among colonists was a legacy of the French and Indian War, which is true. Also true is that the South was divided into military districts by the First Reconstruction Act in 1867.
Step-by-step explanation:
The statement that all of the tribes in the Iroquois Confederacy maintained neutrality during the Revolutionary War is false. The Iroquois Confederacy, also known as the Six Nations, was a powerful confederation of Native American tribes in Northeastern America. During the Revolutionary War, the confederacy was split, with some tribes, such as the Oneida and Tuscarora, siding with the Americans, while others, like the Mohawk, Seneca, Onondaga, and Cayuga, sided with the British.
Concerning Exercise 7.1.1, it is true that an increasing sense of common identity among the colonists was one of the legacies of the French and Indian War. The war fostered a sense of unity against a common enemy and grievances against British colonial policies, setting the stage for the Revolutionary War.
Regarding Exercise 17.2.3, it is also true that according to the First Reconstruction Act passed in 1867, the South was divided into military districts. This was part of the Reconstruction efforts to reorganize the Southern states after the Civil War and to enforce the rights of newly freed African Americans through military oversight.
