Let me give you an 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-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,

The song debuted at 45 on the Billboard Radio Songs chart with 29 million in all-format audience. It debuted on the Mainstream Top 40 chart at number 12, tying it with Mariah Carey's "Dreamlover" (1993) as the highest chart debut. "Shake It Off" became her third number-one song there, following her 2008 country crossover hit single "Love Story" and her 2013 hit "I Knew You Were Trouble", which remained No. 1 for seven consecutive weeks. The single debuted at number nine on the Billboard Adult Top 40 chart, becoming the highest debut single on the chart. On its sixth week, the song became her second No. 1 on the Adult Top 40 chart since her 2013 hit "I Knew You Were Trouble", tying it with Celine Dion's "Because You Loved Me" (1996) as the fastest song to reach number 1 in just six weeks. The song debuted at number 58 on the Country Airplay chart, though only two country stations played the song more than four times. It spent only one week on the chart. Billboard noted that its presence on the chart was unusual due to its sound and Swift's acknowledged transition from country to pop music. On the Radio Songs chart, the song became Swift's third number-one song there, following her 2013 hit "I Knew You Were Trouble". "Shake It Off" has spent four non-consecutive weeks at No. 1 on the Digital Songs chart.
