In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

Let me give you an example: 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,
. Link Information: Operation Market Garden was a failed World War II military operation fought in the Netherlands from 17 to 25 September 1944. Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin?
The answer to this example can be: from 17 to 25 September 1944
Here is why: The passage describes the 704th's actions during Operation Market Garden, and the answer specifies when the operation happened.

Passage: After a series of co-starring film roles, Lopez had her breakthrough when she was cast in the title role of Selena (1997), a biographical film about American singer-songwriter Selena Quintanilla-Perez. Working on the film inspired her to launch a music career, with Lopez saying: "I started my career in musical theater on stage. So doing the movie just reminded me of how much I missed singing, dancing, and the like..." After filming Selena, Lopez was "really feeling [her] Latin roots" and recorded a demo record in Spanish. Her manager sent the song ("Vivir Sin Ti") to Sony Music Entertainment's Work Group, which was interested in signing Lopez. Tommy Mottola, the head of the label, suggested that she sing in English and she began recording her debut album, On the 6. Her decision to launch a musical career was seen as a risk, as film stars had a "patchy record" when it came to releasing pop music, and "If the album was a flop, not only would it embarrass Lopez but it might even damage her career." Lopez originally believed that "Feelin' So Good" was to be released as the album's lead single. "If You Had My Love" was produced by Rodney Jerkins; Lopez recorded her vocals for the song at Sony Music Studios in New York City with engineers Franklyn Grant and Robb Williams. The song was later mixed by Tony Maserati at The Hit Factory in New York City, and subsequently mastered by Herb Powers at Powers House of Sound. Shawnyette Harrell and Jennifer Karr served as backing vocalists.
