Example Input: Question: Did Charles Jones win any tests in the Caribbean? Passage:In 1930, when the MCC visited the Caribbean under the leadership of F.S.G. Calthorpe, Jones played against them three times in February, twice for British Guiana and once whilst making his Test Match debut. His selection for the 3rd Test of the four-match series, played at Bourda, Georgetown was more to do with the West Indies’ usual policy of using a few players from the host island in an effort to keep the expenses down. In an historic victory over England, Jones’ contribution was minimal, scoring just 6 and 2, taking two catches but failing to take a wicket with the ball. He played only occasionally for the next five years but aided by some useful scores with the bat in that time, Jones made a further three Test appearances against England sides led by R.E.S. Wyatt in 1935. In the second Test of the series, played at Port-of-Spain, Trinidad, and where he opened with C.M. Christiani, he scored 19 runs in both innings. This subsequently proved to be his highest Test score but he failed to take a single Test wicket in his career. In all first-class matches he took 24 wickets at an average of 44.12 apiece and scored 917 runs at an average of 21.83. In a career that ended in January 1939, his highest score was an unbeaten 89, scored at home in a comprehensive victory over Barbados. No Obituary appeared within the pages of Wisden for Jones.

Example Input: Question: How many episodes of The Tom and Jerry Show aired before Little Quacker the duckling was introduced? Passage:Another recurring character in the series was Little Quacker the duckling, who was later adapted into the Hanna-Barbera character Yakky Doodle. He appears in Little Quacker (1950), Just Ducky (1953), Downhearted Duckling (1954), Southbound Duckling (1955), That's My Mommy (also 1955), Happy Go Ducky (1958), and The Vanishing Duck (1958). Quacker talks a lot compared to Tom and Jerry. His voice is a 'duck voice' not dissimilar to Disney's Donald Duck. In many shorts, he is the only character who speaks. He is very trusting, even trusting Tom in many situations in which Tom wishes to eat him. He is a friend of Jerry, but unlike Jerry harbors no hard feelings towards Tom. He appeared in The Tom and Jerry Show episode "The Lost Duckling" (1975). He also got his own series of shorts on The Yogi Bear Show (renamed Yakky Doodle) after guesting in several Hanna-Barbera TV shows. Quacker was then used as a template for the 'Hard Luck Duck' character starring in the titular character's short from the What a Cartoon! series. His What a Cartoon! counterpart Hard Luck Duck was voiced by Russi Taylor.
