Question: Was Viborg Ff still operational when Burns earned a place in his first All-Star game? Passage:In 1995, the MLS began an expansion plan to add new teams to the league. In the 1996 MLS Inaugural Allocations, the MLS assigned Burns to the New England Revolution. In August 1995, the MLS loaned out Burns to Danish club Viborg FF. The Revolution retained his rights and Burns returned to play for the Revolution in 1996. In 1998, Burns earned a place in the MLS All-Star game. In the 1999 off-season, he made several attempts to move back to a European club, trying out with clubs such as Utrecht, Bolton and Hearts. None of the clubs expressed interest in him and Burns returned to the Revolution. In June 2000, the Revolution traded Burns, Dan Calichman and a first round draft pick to the San Jose Earthquakes in exchange for Mauricio Wright. Burns finished the 2000 season with the Earthquakes. However, he did not remain with the team and he was traded in March 2001 to the Kansas City Wizards in return for conditional picks in the 2002 MLS SuperDraft. Burns played two seasons with the Wizards, 2001 and 2002. In 2002, he was chosen to play in the 2002 MLS All-Star Game. At the end of the 2002 season, Burns announced his retirement from professional football.

Question: When was the firm that designed the Oregon library established? Passage:The Oregon Library was designed by Chicago architects Pond and Pond. The Ponds were members of the Eagle's Nest Art Colony, founded by Lorado Taft, and their association with Taft and the colony led them to design the library. Their design was influenced by the colony, and a combination of two architectural styles, Classical Revival and the Arts and Crafts movement. The completed library included a second floor art gallery to which members of Eagle's Nest donated works for a permanent collection. The gallery's collection includes 64 paintings and sculptures as well as a Currier and Ives lithograph collection appraised at US$700,000. The Oregon Public Library was listed on the U.S. National Register of Historic Places in 2003, three years later it was included as a contributing property in a historic district that received the National Register designation.

Question: How deep is the body of water where Audrey's formation was first noticed? Passage:The formation and development of Hurricane Audrey was multi-faceted. One contributor to Audrey's formation—an area of anomalously low pressures roughly above sea level—was traced back to its first detection in the western Caribbean Sea on June 11. In an analysis of weather patterns from June 1957, Weather Bureau meteorologist William H. Klein noted the potential for research on similar disturbances to shed light on tropical cyclone development. Concurrently, surface observations suggested the progression of a disorganized tropical wave tracking westward across the Caribbean Sea beginning on June 20, eventually entering the Bay of Campeche on June 22. At 12:00 UTC on June 24 (7:00 a.m. CST), the resulting disturbance organized into a tropical depression based on ship reports in the bay; at the time, the first indication of a developing tropical cyclone originated from a report from a shrimp boat. The depression was in a highly favorable environment for intensification in the western Gulf of Mexico; sea surface temperatures in the area were at , or 3 °F (2 °C) above normal for the time of year. In addition, the latitudinal alignment of a polar trough over the Great Plains and the nascent disturbance in the Bay of Campeche created an environment suitable for outflow in the upper-levels of the atmosphere. Taking advantage of these conditions, Audrey reached tropical storm strength just six hours after being classified as a tropical depression while remaining nearly stationary.
