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-Lo 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,

Q: Question: How many songs on What To Do About Them had been previously unreleased? Passage:In 1992 the band signed to Taang! Records and released the eight-song mini-album What To Do About Them culled from a mix of previously available and unreleased home and studio recordings. Musician/cartoonist Ron Rege, Jr. contributed artwork to the album's cover as well as lo-fi recordings that were woven into the record's sequence. The band also set to work recording their first LP, around which time shifts in Swirlies' personnel began to occur. Ben Drucker only drummed on a third of the new album's studio tracks, and for the remaining songs his parts were handed over to a pair of session drummers. Andy Bernick departed to pursue ornithology for the academic year and Damon's former roommate Morgan Andrews filled in on bass guitar and other noises. It was this line-up that toured to support the new album, Blonder Tongue Audio Baton, and appeared in the video for its lead track, "Bell". Named for an obscure piece of vintage musical equipment, Blonder Tongue Audio Baton made use of Mellotron, Moog, and other analogue artifacts that the group had unearthed in the studio. During sequencing the band threw in numerous lo-fi compositions, soundbites, and rants, and collaged together an album jacket from arrays of found images and objects that matched the album's eclectic aesthetics. Hailed for melding "the high waters of shoegaze creativity and the mounting currents of indie rock", Blonder Tongue Audio Baton quickly rose to prominence in the American noise pop canon.
