The question is about how homeowner Tanya acquired land deposited by a river on her property.
Step-by-step explanation:
The subject of this question is History. The question is asking about how homeowner Tanya acquired the ownership of land that was deposited by a river running through her property.
In some historical contexts, land ownership was determined through a declaration made by the homeowner, establishing the real estate held and the value for calculating taxes. In other contexts, land was held in trust by family heads or village leaders who allocated plots of land to individuals based on usufruct rights, which allowed people to use the land assigned to them but not own or sell it.
The answer to the question depends on the specific historical context, so it is important to provide more information about the time period or region in order to give a more accurate answer.
