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: Of the grasses that the essex skipper eats, which is the longest? Passage 1:Eggs are laid in strings on the stems of grasses where they remain over the winter. The Essex skipper's favoured foodplant is cock's-foot (Dactylis glomerata), and it rarely uses the small skipper's favoured foodplant Yorkshire fog. Essex skippers' other foods include creeping soft grass (Holcus mollis), couch grass (Elymus repens), timothy-grass (Phleum pratense), meadow foxtail (Alopecurus pratensis), false brome (Brachypodium sylvaticum) and tor-grass (Brachypodium pinnatum). This skipper's caterpillars emerge in the spring and feed until June before forming shelters from leaves tied with silk at the base of the foodplant to pupate. Adults fly from July through August. Like most skippers, they are fairly strictly diurnal, though individuals are very rarely encountered during the night.
 Passage 2:He made his "Seals" debut in a 1–1 draw with Cambridge United in August 1972, and went on to bag 41 league goals in 199 appearances in one of the most successful periods in the club's history. A 15th-place finish in the Fourth Division in 1972–73 was followed by a seventh-place finish in 1973–74. Ken Roberts's side achieved promotion in 1974–75 by securing the fourth automatic promotion place with only a slender higher goal average than fifth place Lincoln City. More remarkably, Chester reached the semi-finals of the League Cup, beating Leeds United and Newcastle United along the way. Owen scored in the 2–2 first-leg draw with Aston Villa at Sealand Road, and played in the return game as Chester narrowly lost 3–2 at Villa Park to deny Owen an appearance at Wembley Stadium. Owen finished as the club's top league scorer during the campaign, with 14 goals to his name. He managed double-figures again in 1975–76, as Chester retained their Third Division status. Another mid-table finish was achieved in 1976–77 under player-manager Alan Oakes, and Owen also featured in the FA Cup Fifth Round defeat to Wolverhampton Wanderers at Molineux.
 Passage 3:Kling was instrumental in developing Mercedes' return to international competition in the early 1950s, and his win in the 1952 Carrera Panamericana road race, driving the then-experimental Mercedes-Benz 300SL was a defining point in assuring the Daimler-Benz management that motorsport had a place in Mercedes' future. Called up to the revived Mercedes Grand Prix squad in 1954 he finished less than one second behind the legendary Juan Manuel Fangio on his Formula One debut, taking second place in the 1954 French Grand Prix at the fast Reims-Gueux circuit. This promising start was not to last, and with the arrival of Stirling Moss at Mercedes in 1955 Kling was effectively demoted to third driver. However, away from the World Championship, Kling took impressive victories in both the Berlin Grand Prix (at AVUS, another high-speed circuit) and the Swedish Grand Prix. He left the Formula One team at the end of the season, to succeed Alfred Neubauer as head of Mercedes motorsport. He was in this post during their successful rallying campaigns of the 1960s, occasionally taking the wheel himself. On one such occasion he drove a Mercedes-Benz 220SE to victory in the mighty 1961 Algiers-Cape Town trans-African rally.
