Final answer:
The term for the 17 thousand boys who fled the Sudanese Civil War is 'lostboys', a representation of the countless children displaced by conflicts worldwide.
Step-by-step explanation:
The name given to the group of 17 thousand boys who fled from the Sudanese Civil War is known as the lostboys. These children became a symbol of the suffering and the displacement caused by the prolonged conflict. They embarked on a perilous journey, walking thousands of miles to seek safety, eventually resettling in various countries as refugees. The term refugee is defined as a person who has been forced to leave their country to escape war, persecution, or natural disaster. This term applies to a wide range of people displaced from their homelands, including those affected by the Syrian Civil War, the conflict in Darfur, and the Russian invasion of Ukraine.
