Final answer:
The Georgia Land Lottery succeeded the Yazoo Act, the Homestead Act facilitated western expansion, and the Land Ordinance of 1787 established procedures by which territories could achieve statehood.
Step-by-step explanation:
The land policy that replaced the Yazoo Act was The Georgia Land Lottery (A). This policy was instituted after the Yazoo land fraud scandal, and it distributed land based on a lottery system rather than through potentially corrupt sales.
Regarding the question of the action that the U.S. government took to help Americans fulfill the goal of western expansion, The Homestead Act (A) represents such an action. It provided federal lands in the west to settlers as long as they improved it by building homes and farming.
When discussing the Land Ordinance of 1787, the correct statement is that it specified the process by which a territory could become a state (A). This was part of the series of measures focused on governing and selling the western lands.
