Example Input: Passage: During the Second World War, General Dornberger was the military head of the army's rocket program, Zanssen became the commandant of the Peenemünde army rocket centre, and von Braun was the technical director of the ballistic missile program. They would lead the team that built the Aggregate-4 (A-4) rocket, which became the first vehicle to reach outer space during its test flight program in 1942 and 1943. By 1943, Germany began mass-producing the A-4 as the Vergeltungswaffe 2 ("Vengeance Weapon" 2, or more commonly, V2), a ballistic missile with a 320 kilometers (200 mi) range carrying a 1,130 kilograms (2,490 lb) warhead at 4,000 kilometers per hour (2,500 mph). Its supersonic speed meant there was no defense against it, and radar detection provided little warning. Germany used the weapon to bombard southern England and parts of Allied-liberated western Europe from 1944 until 1945. After the war, the V-2 became the basis of early American and Soviet rocket designs. Question: What was von Braun's role in the army's rocket program during during World War II?
Example Output: technical director of the ballistic missile program

Example Input: Passage: Nontrinitarians, such as Unitarians, Christadelphians and Jehovah's Witnesses also acknowledge Mary as the biological mother of Jesus Christ, but do not recognise Marian titles such as "Mother of God" as these groups generally reject Christ's divinity. Since Nontrinitarian churches are typically also mortalist, the issue of praying to Mary, whom they would consider "asleep", awaiting resurrection, does not arise. Emanuel Swedenborg says God as he is in himself could not directly approach evil spirits to redeem those spirits without destroying them (Exodus 33:20, John 1:18), so God impregnated Mary, who gave Jesus Christ access to the evil heredity of the human race, which he could approach, redeem and save. Question: Which Nontrinitarian theologian says that God cannot approach eveil spirits to redeem them?
Example Output: Emanuel Swedenborg
