Context: Within the city there have been two tram networks in operation. A proposal to develop a horse-drawn tram (linking the city's railway termini) was made by American George Francis Train in the 1860s, and implemented in 1872 by the Cork Tramway Company. However, the company ceased trading in 1875 after Cork Corporation refused permission to extend the line, mainly because of objections from cab operators to the type of tracks which although they were laid to the Irish national railway gauge of 5 ft 3in protruded from the road surface.[citation needed]

Problem: Given the question: Extract the answer to the question from the following context. Question: How long did Jesus Christ rule? Context: Witnesses believe that a "little flock" go to heaven, but that the hope for life after death for the majority of "other sheep" involves being resurrected by God to a cleansed earth after Armageddon. They interpret Revelation 14:15 to mean that the number of Christians going to heaven is limited to exactly 144,000, who will rule with Jesus as kings and priests over earth. Jehovah's Witnesses teach that only they meet scriptural requirements for surviving Armageddon, but that God is the final judge. During Christ's millennial reign, most people who died prior to Armageddon will be resurrected with the prospect of living forever; they will be taught the proper way to worship God to prepare them for their final test at the end of the millennium.

Problem: Given the question: Extract the answer to the question from the following context. Question: Who did the Supreme Court decide was not responsible to solve the segregation problem? Context: On August 18, 1970, the NAACP filed suit against Michigan state officials, including Governor William Milliken, charging de facto public school segregation. The NAACP argued that although schools were not legally segregated, the city of Detroit and its surrounding counties had enacted policies to maintain racial segregation in public schools. The NAACP also suggested a direct relationship between unfair housing practices and educational segregation, which followed segregated neighborhoods. The District Court held all levels of government accountable for the segregation in its ruling. The Sixth Circuit Court affirmed some of the decision, holding that it was the state's responsibility to integrate across the segregated metropolitan area. The U.S. Supreme Court took up the case February 27, 1974. The subsequent Milliken v. Bradley decision had wide national influence. In a narrow decision, the Court found that schools were a subject of local control and that suburbs could not be forced to solve problems in the city's school district.
