Input: Read this: The Luftwaffe's poor intelligence meant that their aircraft were not always able to locate their targets, and thus attacks on factories and airfields failed to achieve the desired results. British fighter aircraft production continued at a rate surpassing Germany's by 2 to 1. The British produced 10,000 aircraft in 1940, in comparison to Germany's 8,000. The replacement of pilots and aircrew was more difficult. Both the RAF and Luftwaffe struggled to replace manpower losses, though the Germans had larger reserves of trained aircrew. The circumstances affected the Germans more than the British. Operating over home territory, British flyers could fly again if they survived being shot down. German crews, even if they survived, faced capture. Moreover, bombers had four to five crewmen on board, representing a greater loss of manpower. On 7 September, the Germans shifted away from the destruction of the RAF's supporting structures. German intelligence suggested Fighter Command was weakening, and an attack on London would force it into a final battle of annihilation while compelling the British Government to surrender.
Question: What did German crew members face if they were shot down over Britain?

Output: capture

Input: Read this: The U.S. framed the war as part of its policy of containment of Communism in south Asia, but American forces were frustrated by an inability to engage the enemy in decisive battles, corruption and incompetence in the Army of the Republic of Vietnam, and ever increasing protests at home. The Tet Offensive in 1968, although a major military defeat for the NLF with half their forces eliminated, marked the psychological turning point in the war. With President Richard M. Nixon opposed to containment and more interested in achieving detente with both the Soviet Union and China, American policy shifted to "Vietnamization," providing very large supplies of arms and letting the Vietnamese fight it out themselves. After more than 57,000 dead and many more wounded, American forces withdrew in 1973 with no clear victory, and in 1975 South Vietnam was finally conquered by communist North Vietnam and unified.
Question: What was the sociological turning point of the war?

Output: unanswerable
