The correct answer to this open question is the following.
Although there are no options attached or further context or references, we can comment on the following.
The price offered for Alcatraz Island ($9.40) was fair because it was practically the amount the government originally paid the Native Indians or 47 cents per acre.
After closing the prison in 1963, the government's idea was to sell it to private investors but that is when Native American Indian protests started. Native Indians argued the existence of a treaty that said that if the government abandoned federal land, it had to be returned to the Indians.
These Native American Indians influenced the United States government and raised the spirit of their community by occupying Alcatraz.
