I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "In 1952, the United States elected a new president, and on 29 November 1952, the president-elect, Dwight D. Eisenhower, went to Korea to learn what might end the Korean War. With the United Nations' acceptance of India's proposed Korean War armistice, the KPA, the PVA, and the UN Command ceased fire with the battle line approximately at the 38th parallel. Upon agreeing to the armistice, the belligerents established the Korean Demilitarized Zone (DMZ), which has since been patrolled by the KPA and ROKA, United States, and Joint UN Commands."?

What happened on the 29th day of the 11th month of the 52nd year of the 20th century?
