[Q]: Passage: Under the 1963 constitution, Massamba-Débat was elected President for a five-year term. During Massamba-Débat's term in office the regime adopted "scientific socialism" as the country's constitutional ideology. In 1965, Congo established relations with the Soviet Union, the People's Republic of China, North Korea and North Vietnam. Massamba-Débat's regime also invited several hundred Cuban army troops into the country to train his party's militia units and these troops helped his government survive a coup in 1966 led by paratroopers loyal to future President Marien Ngouabi. Nevertheless, Massamba-Débat was unable to reconcile various institutional, tribal and ideological factions within the country and his regime ended abruptly with a bloodless coup d'état in September 1968. Question: When did Massamba-Debat lose power in the Congo?
[A]: September 1968


[Q]: Passage: Paris' manufacturing is mostly focused in its suburbs, and the city itself has only around 75,000 manufacturing workers, most of which are in the textile, clothing, leather goods and shoe trades. Paris region manufacturing specialises in transportation, mainly automobiles, aircraft and trains, but this is in a sharp decline: Paris proper manufacturing jobs dropped by 64 percent between 1990 and 2010, and the Paris region lost 48 percent during the same period. Most of this is due to companies relocating outside the Paris region. The Paris region's 800 aerospace companies employed 100,000. Four hundred automobile industry companies employ another 100,000 workers: many of these are centred in the Yvelines department around the Renault and PSA-Citroen plants (this department alone employs 33,000), but the industry as a whole suffered a major loss with the 2014 closing of a major Aulnay-sous-Bois Citroen assembly plant. Question: What does Paris region manufacturing specialize in?
[A]: transportation


[Q]: Passage: In 1953, the Republican Party's Old Guard presented Eisenhower with a dilemma by insisting he disavow the Yalta Agreements as beyond the constitutional authority of the Executive Branch; however, the death of Joseph Stalin in March 1953 made the matter a practical moot point. At this time Eisenhower gave his Chance for Peace speech in which he attempted, unsuccessfully, to forestall the nuclear arms race with the Soviet Union by suggesting multiple opportunities presented by peaceful uses of nuclear materials. Biographer Stephen Ambrose opined that this was the best speech of Eisenhower's presidency. Question: Who called the Chance for Peace speech the best one Eisenhower gave as president?
[A]:
Stephen Ambrose
