Example: 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.

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-Lô during 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.

Problem: Question: How many horses did Kinghaven Farms own when Alydeed won the Derby Trial? Passage:Alydeed was owned and raced by David Willmot's Kinghaven Farms. Racing from a base at Woodbine Racetrack in Toronto, at age two his best performances were wins in an allowance race at Gulfstream Park in Florida, where he equalled the track record for 6.5 furlongs, and a win in Woodbine's Victoria Stakes. At age three, Alydeed won five of his ten starts. Near the end of April 1992, he was sent to Churchill Downs in Louisville, Kentucky where he won the Derby Trial. Based on his strong performance, his handlers decided to run him in the second leg of the U.S. Triple Crown series, the Preakness Stakes where he ran second to Pine Bluff. Back at Woodbine Racetrack, he won the Plate Trial Stakes then ran away from the field in the final quarter of a mile to win Canada's most prestigious race, the Queen's Plate. In the second leg of the Canadian Triple Crown series, the Prince of Wales Stakes, Alydeed was sent off as the prohibitive favorite at 1/9 odds. However, on a muddy Fort Erie Racetrack, Alydeed ran second to Benburb. Alydeed then elected to skip the third jewel of the Canadian Triple Crown opting for the Grade 1 Travers Stakes at Saratoga Race Course where he finished eighth to Thunder Rumble as the 8-5 favourite.
