106. In surveying, monuments are used to establish
Answer: B
Monuments are used to establish real estate boundaries.
Monuments serve as fixed reference points that delineate property lines and boundaries in surveying, making them essential for defining real estate boundaries.
A) a common address.
While monuments can provide reference points for addresses, they are not primarily used for establishing a common address. Addresses are more about location identification rather than boundary demarcation.
B) real estate boundaries.
This option is correct as monuments are specifically utilized in surveying to mark the boundaries of real estate. They provide a physical marker that helps in accurately defining property lines.
C) flood elevation.
Monuments are not used to determine flood elevation. Flood elevation is typically assessed using hydrological studies and topographical data, rather than physical markers used for boundary identification.
D) historical sites.
Although monuments may sometimes indicate historical sites, their primary function in surveying is not related to historical preservation. They focus on establishing property boundaries rather than cataloging historical locations.
Conclusion
Monuments are crucial in surveying for establishing real estate boundaries, making Option B the only correct choice. Other options either misinterpret the function of monuments or relate to concepts unrelated to their primary use in boundary determination.
