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. 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-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. 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,

Problem: Question: Were both of the artists that Nat Riddles performed and recorded with born in the U.S.? Passage:Around this time Gussow, a Princeton graduate and English M.A. student at Columbia University, first saw Magee and his trio performing on the corner of 114th Street and Broadway. (Gussow relates the story in his 1998 blues memoir, Mister Satan's Apprentice.) Gussow, a guitarist and harmonica player whose performing experience had previously been limited to a handful of high school and college bands, was galvanized by the encounter. After dropping out of grad school, Gussow spent several years as a part-time street performer in New York and Europe. Gussow's transformation from an academic to a blues player was facilitated by lessons he took from his mentor, New York harmonica virtuoso Nat Riddles, who had performed and recorded with Larry Johnson, Odetta, and others, and by his acculturation into the jam session life at Dan Lynch, a storied East Village juke joint.
