In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: What was the age of Lea Sirk the year that she placed twenty-second in the Eurovision Song Contest? Passage 1:Morton was a prolific photographer who took photographs of all aspects of life in North Carolina. His first published photograph came in 1935, when he was 14; a picture he took of a golfing scene was published as a North Carolina travel advertisement in Time Magazine. During his time at the University of North Carolina, he was a photographer for the student newspaper, the Daily Tar Heel. During World War II, Morton joined as a member of the Signal Corps, where he was assigned the job of newsreel photographer. He was sent to New Caledonia, an island off the coast of Australia, where he was attached to the 37th Infantry Division. Near the end of the war, Morton was assigned to take pictures of General Douglas MacArthur when MacArthur's regular photographer was sick. While on the island of Luzon in the Philippines, Morton was injured by a Japanese explosive and was awarded the Bronze Star and the Purple Heart.
 Passage 2:A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. In 1931, the German engineer Bruno Lange developed a photo cell using silver selenide in place of copper oxide, although the prototype selenium cells converted less than 1% of incident light into electricity. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954. These early solar cells cost US$286/watt and reached efficiencies of 4.5–6%. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs. The surface passivation process has since been critical to solar cell efficiency.
 Passage 3:Prior to the 2020 Contest, Slovenia had participated in the Eurovision Song Contest twenty-five times since its first entry in . Slovenia's highest placing in the contest, to this point, has been seventh place, which the nation achieved on two occasions: in 1995 with the song "Prisluhni mi" performed by Darja Švajger and in 2001 with the song "Energy" performed by Nuša Derenda. The country's only other top ten result was achieved in 1997 when Tanja Ribič performing "Zbudi se" placed tenth. Since the introduction of semi-finals to the format of the contest in 2004, Slovenia had thus far only managed to qualify to the final on six occasions. In 2018, Slovenia was represented by Lea Sirk and the song "Hvala, ne!", which qualified to the final and placed twenty-second. One year later, in 2019, Slovenia qualified for the final again with Zala Kralj & Gašper Šantl, finishing in fifteenth place with the song "Sebi".
