Question: How old is the school that Arizona faced in the Las Vegas Bowl? Passage 1:After going 6–6 in 2006, the Wildcats lost three of their first four games in 2007, including a 29–27 loss at home to New Mexico. In that game, Stoops gained a 15-yard unsportsmanlike conduct penalty for his behavior on the sideline, which led to a New Mexico touchdown. Following a 2007, 21–20 home loss to Stanford, dropping the team to 2–6, local media began speculating as to whether Stoops would be fired. However, subsequent statements by the athletic director and the university's president indicated that Stoops would return for an additional season. At the beginning of the season, many believed this to be the year Stoops and the Wildcats would reach their first college bowl game in a decade; a winning season was considered a must in order for Stoops to remain as Wildcats head coach. Under the direction of Stoops, Arizona scored 70 points in the season opener against the Idaho Vandals, falling just four points short of a school record for points scored in a game. They went on to soundly defeat Toledo, UCLA, Washington, and California, but lost close games to New Mexico and Stanford. They went on to defeat Washington State on the road to secure bowl eligibility at six wins, but lost to Oregon on the road after mounting a dramatic second-half come-from-behind rally, and to Oregon State in Tucson on a last-second field goal. The Wildcats' final game of the regular season was a 31–10 victory on December 6 in Tucson against Arizona State in the annual Territorial Cup rivalry game. With that win and a final regular season record of 7–5, Arizona accepted a bid from to the Las Vegas Bowl to face BYU. It was the Wildcats' first bowl appearance since the 1998 Holiday Bowl. Stoops' reputation in Tucson was mixed; while the Wildcats had a winning record and appeared in and won their first bowl game in ten years, many fans were divided during the season on whether he should be retained as head coach, as they expected Stoops to guide the team to an eight, nine or even ten-win season given the talent level and the offensive and defensive systems employed by the Wildcats (and with the overall talent level in the Pac-10 conference perceived to be not as strong as usual in 2008). While Stoops brought the Wildcat football program to a level of respectability which was lost during the era of John Mackovic, some fans were disappointed the program was not at the elite level of Stoops' former program Oklahoma or of perennial Pac-10 football power USC. However, Stoops was given strong votes of confidence by UA (later UNLV) athletic director Jim Livengood, by university president Dr. Robert Shelton, and by several prominent Arizona football boosters.
 Passage 2:On 4 May 1918, in the aftermath of the Finnish Civil War, Silatch arrived secretly in Kotka, Finland, to evacuate remaining members of the Finnish Red Guard. However, she was confiscated by the Finns and joined the Finnish icebreaker fleet as Ilmarinen, after the legendary hero from Kalevala. In December 1919 she was sent to Koivisto to assist three Finnish torpedo boats, C1, C2 and C3 that had been surrounded by ice some thick. The 150-ton torpedo boats had participated in the British campaign in the Baltic, and Admiral Walter Cowan had demanded that the Finnish squadron patrolling the area had to stay until the British forces had withdrawn. Despite the efforts of Ilmarinen, the weak-hulled torpedo boats were crushed by the ice, and the newly founded Finnish Navy lost one fifth of its ships. After the winter of 1919 Ilmarinen was laid up until she was returned to the Soviet Union according to the Treaty of Tartu. In turn the Soviets gave back the Finnish icebreaker Avance. The name Ilmarinen was later given to a Finnish coastal defence ship launched in 1931.
 Passage 3:The present-day Angels franchise began play as the Los Angeles Angels in . Owned by actor Gene Autry and his wife Jackie, they played their inaugural season at Wrigley Field in South Los Angeles (not to be confused with the Chicago stadium of the same name). They moved to Dodger Stadium the following season, becoming tenants of the National League's Los Angeles Dodgers for four seasons. During the season, Gene Autry struck a deal with the suburban city of Anaheim on a new stadium for the Angels. The team changed its name to California Angels late in the season, as they were the only American League team in the state at the time, and moved to the city-owned Anaheim Stadium in . They would play under this moniker for over 30 seasons.
