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 year did Cucelli and Del Bello play their first doubles match? Passage 1:When the ultimate goal of plasma processing is a purified plasma component for injection or transfusion, the plasma component must be highly pure. The first practical large-scale method of blood plasma fractionation was developed by Edwin J. Cohn during World War II. It is known as the Cohn process (or Cohn method). This process is also known as cold ethanol fractionation as it involves gradually increasing the concentration of ethanol in the solution at 5C and 3C. The Cohn Process exploits differences in properties of the various plasma proteins, specifically, the high solubility and low pI of albumin. As the ethanol concentration is increased in stages from 0% to 40% the [pH] is lowered from neutral (pH ~ 7) to about 4.8, which is near the pI of albumin. At each stage certain proteins are precipitated out of the solution and removed. The final precipitate is purified albumin. Several variations to this process exist, including an adapted method by Nitschmann and Kistler that uses fewer steps and replaces centrifugation and bulk freezing with filtration and diafiltration.
 Passage 2:Collard made his debut for Cambridgeshire in the 1971 Minor Counties Championship against Bedfordshire. Collard played Minor counties cricket for Cambridgeshire from 1971 to 1992, including 108 Minor Counties Championship matches and 14 MCCA Knockout Trophy matches. In 1975, he made his List A debut against Northamptonshire in the Gillette Cup. He played four further List A matches for Cambridgeshire, the last coming against Worcestershire in the 1989 NatWest Trophy. In his five List A matches, he scored 17 runs at a batting average of 8.50, with a high score of 9. With the ball he took 5 wickets at a bowling average of 33.20, with best figures of 3/38.
 Passage 3:Giovanni Cucelli (born as Giovanni Kucel) (1916–1977) was an Italian tennis player. He played Davis Cup for Italy and formed a great doubles partnership with Marcello Del Bello. Because of World War 2, Cucelli was 30 by the time he made his Grand Slam debut at Wimbledon in 1947, where he lost in the third round to Jack Kramer. At Roland Garros (held just after Wimbledon) Cucelli beat veteran Jack Crawford and Robert Abdesselam before losing to defending champion Marcel Bernard in five sets in the quarter finals. At Roland Garros in 1948, Cucelli beat a young Frank Sedgman before losing to Frank Parker in the quarter finals. At Wimbledon Cucelli beat Jaroslav Drobny before losing to Tony Mottram in round three. At Roland Garros in 1949, Cucelli reached his third consecutive quarter final, where he lost to Budge Patty. At Wimbledon he beat Mottram before losing to Eric Sturgess in the last 16. At 1949 U. S. championships, Cucelli lost in round two to Sam Match. Cucelli lost in the last 16 of Roland Garros in 1950 to Patty. After early exits at the French and Wimbledon in 1951, Cucelli reached the last 16 at Roland Garros in 1952, where he lost to Ken McGregor. He lost early at Wimbledon to Mottram. Cucelli lost his first match at Roland Garros in 1953 to Rex Hartwig. In 1955 Cucelli turned professional. Cucelli won a lot of tournaments during his career: Italian Riviera championships and Alassio in 1939, Napoli and Barcelona Christmas tournament in 1941, St. Moritz, French-Switzerland championships and Milan international in 1946, Swiss championships, Villars, Montana-Vermala, Viareggio and Rapallo in 1947, Milan international, Napoli, Rapallo, Montecatini and Barcelona Christmas tournament in 1948, San Remo in 1949, Lugano, Istanbul, Venice and Lugano Lido tournament in 1950, San Pellegrino and Viareggio in 1951 and Cava De Tirreni in 1952. He was runner up at Monte Carlo in 1948 to Jozsef Asboth and 1949 to Parker and runner up at Rome in 1951 (where he beat Patty before losing to Drobny).
