Example input: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Loduring July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,

Q: Question: Was Trudeau a member of the democratic socailist Cooperative Commonwealth Federation when he legalized homosexuality? Passage:Many young people in Canada at this time, especially young women, were influenced by the 1960s counterculture and identified with Trudeau, an energetic nonconformist who was relatively young. They were dazzled by his "charm and good looks", and a large fan base was established throughout the country. He would often be stopped in the streets for his autograph or for photographs. Trudeau had once sympathized with Marxists and had spent time in the democratic socialist Cooperative Commonwealth Federation, and many of his fans were attracted to his culturally liberal stances (he legalized homosexuality and created more flexible divorce laws as Justice Minister under Lester B. Pearson). Trudeau was also admired for his laid-back attitude and his celebrity relationships; in that word's prevailing use at the time, describing a modern, "hip and happening person", he was often described as a swinger. A high point happened during Trudeau's election campaign in 1968 during the annual Saint-Jean-Baptiste Day parade in Montreal, when rioting Quebec separatists threw rocks and bottles at the grandstand where Trudeau was seated. Rejecting the pleas of his aides that he take cover, Trudeau stayed in his seat, facing the rioters, without any sign of fear. The image of the politician showing such courage impressed the Canadian people, and he handily won the election the next day.
