Final answer:
The result of the United Nations' plan to divide Mandatory Palestine was the partition of the territory into separate Jewish and Arab states, with Jerusalem placed under international control. The plan led to civil war and the displacement of Palestinian Arabs.
Step-by-step explanation:
In 1947, the United Nations voted to partition Mandatory Palestine into separate Jewish and Arab states as a solution to the ongoing conflict. The plan allocated about 56 percent of the territory to the Jewish population and about 44 percent to the Palestinian Arabs. Jerusalem was to be placed under international trusteeship. However, the plan was met with resistance and led to civil war and the displacement of Palestinian Arabs. On May 14, 1948, Israel declared its independence based on the UN borders, which was followed by a war with neighboring Arab countries.
