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?

Ex Output:
technical director of the ballistic missile program

Passage: The structure known as "Virgil's tomb" is found at the entrance of an ancient Roman tunnel (also known as "grotta vecchia") in Piedigrotta, a district two miles from the centre of Naples, near the Mergellina harbor, on the road heading north along the coast to Pozzuoli. While Virgil was already the object of literary admiration and veneration before his death, in the Middle Ages his name became associated with miraculous powers, and for a couple of centuries his tomb was the destination of pilgrimages and veneration. Question: In which district is "Virgil's tomb" located?

Ex Output:
Piedigrotta

Passage: Those involved in producing professional wrestling have developed a kind of global fraternity, with familial bonds, shared language and passed-down traditions. New performers are expected to "pay their dues" for a few years by working in lower-profile promotions and working as ring crew before working their way upward. The permanent rosters of most promotions develop a backstage pecking order, with veterans mediating conflicts and mentoring younger wrestlers. For many decades (and still to a lesser extent today), performers were expected to keep the illusions of wrestling's legitimacy alive even while not performing, essentially acting in character any time they were in public. Some veterans speak of a "sickness" among wrestling performers, an inexplicable pull to remain active in the wrestling world despite the devastating effects the job can have on one's life and health. Question: What effects can wrestling have on the wrestlers? 

Ex Output:

devastating effects the job can have on one's life and health
