Question

according to the armistice, the demilitarized zone (dmz) was established to
○ ensure that the provisions of the agreement
were met.
○ give the un a foothold in the region.
○ create a barrier between the two sides.
○ prevent the reunification of korea.

Explanation:

The Demilitarized Zone (DMZ) established by the armistice (e.g., Korean War armistice) was to create a physical barrier between the two opposing sides (North and South Korea) to prevent further hostilities. The other options: ensuring agreement provisions were met is not the DMZ's main purpose, the UN foothold is incorrect, and preventing reunification was not its intent (reunification was a political issue, not the DMZ's goal).

Answer:

C. create a barrier between the two sides.
