During this time, Walker won the SFL young player of the month award for September 2004. After his short-term deal at Broadwood, Walker went to Sweden for a couple of months but decided to come back home. he joined Morton in July 2005.

Example Input: Question: Which team was ranked the highest at the 2009 Pacific Nations Cup? Passage:The 2009 Pacific Nations Cup is a rugby union tournament held between five national sides on the Pacific Rim: Fiji, Japan, Samoa, Tonga and the Junior All Blacks. The New Zealand Māori team that won the tournament last year will no longer take part in this competition because of a decision taken by the New Zealand Rugby Union. Australia A has also decided to pull out due to a similar decision. The inaugural competition was held in 2006. This year the tournament will begin on June 12 and ends on July 3, 2009 and most of the matches will be hosted by Fiji. The awarding of the key international tournament to the Fiji Rugby Union represents a further boost to the continued development of rugby in the region. The two opening round matches will be played outside of Fiji with Samoa hosting the Junior All Blacks in Apia and Tonga entertaining the Fijians in Nukuʻalofa the following day before the tournament moves to Fiji for a 17-day festival of international rugby spread across three match venues: the ANZ National Stadium (Suva), Churchill Park (Lautoka) and Lawaqa Park (Sigatoka).

Example Input: Question: Who founded the company that publishes Jasanoff's 2017 book? Passage:Jasanoff's 2017 book, The Dawn Watch: Joseph Conrad in a Global World, published by Penguin Press and in the UK by William Collins centers on the life and times of novelist Joseph Conrad. The Times lauded the book as the "Conrad for our time," and The Spectator called her an "enviably gifted writer...her historian's eye can untie knots that might baffle the pure critic," noting that she "steers us securely and stylishly through those latitudes where Conrad witnessed the future scupper the past." In the judgment of the Financial Times: "This is an unobtrusively skilful, subtle, clear-eyed book, beautifully narrated," while the Literary Review observes: "Written with a novelist's flair for vivid detail and a scholar's attention to texts, The Dawn Watch is by any standard a major contribution to our understanding of Conrad and his time." Reviewing the book in The Guardian, Patrick French began: "The Dawn Watch will win prizes, and if it doesn't, there is something wrong with the prizes." In The Hindu, Sudipta Datta wrote that Jasanoff's approach to Conrad makes for a "remarkable retelling of Joseph Conrad's life and work and its resonance with the present dysfunctional world." In The Guardian, William Dalrymple named the book to his list of best holiday reads of 2017. According to the Wall Street Journal's reviewer, "'The Dawn Watch' is the most vivid and suggestive biography of Conrad ever written." In The New York Times, Ngugi wa Thiong'O applauded the book as "masterful." Thiong'O wrote that Jasanoff succeeded where "An Image of Africa: Racism in Joseph Conrad's Heart of Darkness," Chinua Achebe's classic Conrad essay, had failed, specifically in bringing into clear relief "Conrad's ability to capture the hypocrisy of the 'civilizing mission' and the material interests that drove capitalist empires, crushing the human spirit." "'The Dawn Watch,' Thiong'O wrote, "will become a creative companion to all students of his work. It has made me want to re-establish connections with the Conrad whose written sentences once inspired in me the same joy as a musical phrase."
