Question: Question: How tall is the player that was brought back to Boston in a February 24, 2005 trade that involved Payton? Passage:Prior to the 2004–05 season, the Lakers traded Payton and Rick Fox to the Boston Celtics for center Chris Mihm, small forward Jumaine Jones and point guard Chucky Atkins.

Question: Question: Which company was larger the year that tenders were requested by the Anzac Ship Project, Royal Schelde or Yarrow Shipbuilders? Passage:The Anzac class originated from RAN plans to replace the six River-class destroyer escorts with a mid-capability patrol frigate. The Australian shipbuilding industry was thought to be incapable of warship design, so the RAN decided to take a proven foreign design and modify it. Around the same time, the Royal New Zealand Navy (RNZN) was looking to replace four Leander-class frigates; a deterioration in New Zealand-United States relations, the need to improve alliances with nearby nations, and the commonalities between the RAN and RNZN ships' requirements led the two nations to begin collaborating on the acquisition in 1987. Tenders were requested by the Anzac Ship Project at the end of 1986, with 12 ship designs (including an airship) submitted. By August 1987, the tenders were narrowed down in October to Blohm + Voss's MEKO 200 design, the M class (later Karel Doorman class) offered by Royal Schelde, and a scaled-down Type 23 frigate proposed by Yarrow Shipbuilders. In 1989, the Australian government announced that Melbourne-based shipbuilder AMECON (which became Tenix Defense) would build the modified MEKO 200 design. The Australians ordered eight ships, while New Zealand ordered two, with an unexercised option for two more.
