Input: Question: What stadium did Kifle make his first international appearance for Eritrea at the age of 21 while running 3000 metres? Passage 1:In his book , author Charles Wheelan wrote "We Chicagoans can drive around the city and literally point to things that Rosty built." Although Rostenkowski never "literally" built anything with his own money or labor, he delivered federal funds for Chicago and the State of Illinois. Some of his notable projects include: securing $32 million for the Blue Line of the Chicago Transit Authority which expanded travel from the Chicago Loop to O'Hare International Airport, $450 million to repave and expand the Kennedy Expressway, $25 million to fix the dangerous S Curve on Lake Shore Drive $4 billion for the Deep Tunnel Project, which was designed to keep raw sewage from entering the Chicago River and Lake Michigan, while also protecting over half a million suburban and city home owners threatened by flooded basements. He followed that with $42.4 million for reservoirs in McCook and Thornton Townships and by O'Hare airport, $16.8 million for downtown's State Street Mall renovation, $3.5 million for the construction of the Cook County Boot Camp, a military-style alternative for first-time youthful offenders. When the Chicago White Sox baseball team was considering moving to Florida, Rostenkowski secured a $150 million bond authority for the construction of US Cellular Field. Once nearly abandoned and left in disrepair, he ensured $75 million in tax-free bonds for the remodeling of Navy Pier, which today has become Chicago's preeminent tourist attraction. To ease erosion that threatened Lake Shore Drive and several harbors and museums along the Chicago lake front, Rostenkowski secured $2.2 million for the Chicago Shoreline Protection Project, and laid the foundation for a coordinated partnership among the Army Corps of Engineers, the federal government and the City of Chicago. He also was responsible for securing funding for the upkeep of Chicago area bridges including the Chicago Skyway, the Division, Cermak, and Roosevelt street bridges.
 Passage 2:Kifle was born in Adi Billai in Eritrea's Debub Region. He made his first international appearance for Eritrea at the age of 21, running in the 3000 metres at the 1999 IAAF World Indoor Championships. He finished in last place and was over twenty seconds behind the rest of the runners. His first international outdoor competition followed later that year and he ran in the heats of the 5000 metres at the 1999 World Championships in Athletics in Seville. In 2000 he came 61st at the 2000 IAAF World Cross Country Championships and made his Olympic debut with a performance in the heats of the 10,000 metres at the 2000 Sydney Olympics. He began to improve from the 2002 season onwards: he was eighth in the long race at the 2000 IAAF World Cross Country Championships, fourth at the 2002 IAAF World Half Marathon Championships with a time of 1:01:05 hours, and came sixth over 5000 m at the 2002 African Championships in Athletics. He also won the Cursa de Bombers 10K in Spain that year.
 Passage 3:During the Battle of Gettysburg, the dirt Wheatfield Road was used by various Union and Confederate troops (e.g., Crawford's Third Division of Pennsylvania Reserves), and Union troops deployed artillery westward to the Peach Orchard using the road. In 1884, the Round Top Branch's wye with double spurs and station was built at the east end of Wheatfield Road, and in 1894 the Gettysburg Electric Railway was laid along a west portion of the road (trolleys also crossed the east end near Round Top Station). In 1895, the Commonwealth of Pennsylvania ceded jurisdiction of Wheatfield Road to the War Department, and in 1900 two cast iron identification tablets were placed to label the road. The Gettysburg Electric Railway tracks were removed from the Wheatfield Road in 1917 and the road was repaired in 1931. The Wheatfield Road was resurfaced with asphalt west of Sykes Avenue in 1933, and completed "from the Rosensteel pavilion to the Taneytown road" in 1940 by the McMillan Woods Civilian Conservation Corps camp.
