Final answer:
The First Reconstruction Act of 1867 indeed divided the South into military districts as part of the post-Civil War reconstruction efforts, which is true.
Step-by-step explanation:
In response to your question about the First Reconstruction Act of 1867, it is true that the South was divided into military districts. The federal government was responsible for overseeing the reconstruction of the southern states after the Civil War, and part of this process was separating the South into these districts. This division was intended to maintain order and facilitate the transition of the southern states back into the Union with new state constitutions that afforded civil rights to freed slaves.
