Input: Consider Input: Question: On what date did Recitation win its maiden race at Newbury Racecourse? Passage:After finishing third over five furlongs on his racecourse debut, Recitation won a maiden race over the same distance at Newbury Racecourse, beating I'll See You by half a length. The colt was then moved up sharply in class for the Group Three Coventry Stakes over six furlongs at Royal Ascot in June in which he was ridden by Greville Starkey and started at odds of 11/1. In a performance which Timeform described as "a revelation", Recitation took the lead a quarter mile from the finish and drew clear of the field to win easily by five lengths from Motavato, Bel Bolide and Another Realm. The form of the race was subsequently boosted when the third and fourth placed horses won the Gimcrack Stakes and the Richmond Stakes respectively. In the July Stakes at Newmarket Racecourse Recitation started 2/5 favourite against two opponents, but was beaten two and a half lengths by Age Quod Agis.

Input: Consider Input: Question: Who won the Memorial Cup in 1963 before Ron Ellis won it? Passage:Ellis was signed by the Leafs and played junior hockey with the Toronto Marlboros of the Ontario Hockey Association from 1961–1964. He played on the team that won the Memorial Cup in 1964. Ellis became a full-time Leaf in 1964–65 and played 11 seasons to 1974–75, winning the Stanley Cup in 1967. He was also a member of Team Canada at the 1972 Summit Series. Ellis retired at age 30 during training camp in 1975, coming off the most productive season of his career with 61 points. He said he no longer had the desire to play and denied that his decision had anything to do with being passed over as team captain in favour of Darryl Sittler a month earlier. In 1977, Ellis came out of retirement to play for Canada at the world hockey championships and then decided to resume his NHL career with the Leafs in 1977–78.
