Context_1 : A commencement speech or commencement address is a speech given to graduating students, generally at a university, generally in the United States, although the term is also used for secondary education institutions. The "commencement" is a ceremony in which degrees or diplomas are conferred upon graduating students. A commencement speech is typically given by a notable figure in the community, during the "commencement exercise". The person giving such a speech is known as a commencement speaker. Very commonly, colleges or universities will invite politicians, important citizens, or other noted speakers to come and address the graduating class. Context_2 : The Jeremiah Wright controversy gained national attention in the United States, in March 2008 when ABC News, after reviewing dozens of U.S. Presidential candidate Barack Obama's pastor Jeremiah Wright's sermons, excerpted parts which were subject to intense media scrutiny. Wright is a retired senior pastor of Trinity United Church of Christ in Chicago and former pastor of President Obama. Obama denounced the statements in question, but critics continued to press the issue of his relationship with Wright. In response to this, he gave a speech titled "A More Perfect Union", in which he sought to place Wright's comments in a historical and sociological context. In the speech, Obama again denounced Wright's remarks, but did not disown him as a person. The controversy began to fade, but was renewed in late April when Wright made a series of media appearances, including an interview on "Bill Moyers Journal", a speech at the NAACP, and a speech at the National Press Club. After the last of these, Obama spoke more forcefully against his former pastor, saying that he was "outraged" and "saddened" by his behavior, and in May he resigned his membership in the church. Context_3 : Wallace John Challens, {'1': ", '2': ", '3': ", '4': "} (14 May 1915 – 1 March 2002) was a British scientist and civil servant. A graduate of University College, Nottingham, he began working at the Royal Arsenal in Woolwich in 1936. In 1939, he was transferred to the rocket department. After the defeat of Germany, he was sent to the United States as part of the British Scientific Mission to work on the V-1 flying bomb and the V-2 rocket. On returning to the United Kingdom in 1947, he was recruited by William Penney for the British atomic bomb project. He led the team that developed the firing circuits for the bomb used in Operation "Hurricane", the first British nuclear test. He later developed a neutron generator. He took part in most of the British nuclear tests at Maralinga, and was the scientific director of the Operation "Grapple" tests in 1957. He subsequently became the AWRE's Assistant Director in 1965, Deputy Director in 1972, and Director from 1976 until his retirement in 1978. Context_4 : Operation Grapple was the codeword used to cover UK defence operations in support of the UN peacekeeping missions in the former Yugoslavia (authorised by UNSCR 776 of September 1992); including the deployment of British forces in Bosnia and Croatia from October 1992 until December 1995 as part of the United Nations Protection Force (UNPROFOR). UNPROFOR would eventually hand over the peacekeeping mission in Bosnia to NATO's Implementation Force (IFOR) in winter 1995. The British participation in the IFOR was called Operation Resolute; the whole NATO mission was called Operation Joint Endeavour. The IFOR mission would last approximately a year, before it transitioned to the follow-on Stabilisation Force in Bosnia and Herzegovina (SFOR). Context_5 : United States v. New Wrinkle, Inc., 342 U.S. 371 (1952), is a 1952 Supreme Court decision in which the Court held that a claim of conspiracy to fix uniform minimum prices and to eliminate competition throughout substantially all of the wrinkle finish industry of the United States by means of patent license agreements was, if proved, a violation of § 1 of the Sherman Act. That one of the defendants, a patent-holding company, abstained from manufacturing activities, did not ship goods in commerce, and engaged solely in patent licensing did not insulate its activity from § 1. Making these license contracts for the purpose of regulating distribution and fixing prices of commodities in interstate commerce is subject to the Sherman Act, even though the isolated act of contracting for the licenses occurs within a single state. Patents give no protection from the prohibitions of the Sherman Act when the patent licensing agreements are used to restrain interstate commerce and fix prices of goods shipped in commerce. Context_6 : Midway Stock Farm Barn is a historic building located north of Keosauqua, Iowa, United States. The barn was built by William A. Barker around 1880. It gained historical significance when his son Webb installed equipment made by the Louden Machinery Company of Fairfield, Iowa. By doing so he converted the facility from one that raised livestock to a dairy operation. Around 1918 Barker built an addition onto the south side of the barn and installed a litter carrier with tracks and switches on the ground floor, a hay carrier with a steel track and grapple hook hay fork also on the main floor, and a metal aerator on the roof. It is one of few local operations that still has the Louden equipment. The barn was listed on the National Register of Historic Places in 1999. Context_7 : "Imminent lawless action" is a standard currently used that was established by the United States Supreme Court in "Brandenburg v. Ohio" (1969), for defining the limits of freedom of speech. "Brandenburg" clarified what constituted a "clear and present danger", the standard established by "Schenck v. United States" (1919), and overruled "Whitney v. California" (1927), which had held that speech that merely advocated violence could be made illegal. Under the imminent lawless action test, speech is not protected by the First Amendment if the speaker intends to incite a violation of the law that is both imminent and likely. While the precise meaning of "imminent" may be ambiguous in some cases, the court provided later clarification in "Hess v. Indiana" (1973). In this case, the court found that Hess's words did not fall outside the limits of protected speech, in part, because his speech "amounted to nothing more than advocacy of illegal action at some indefinite future time," and therefore did not meet the imminence requirement. Context_8 : Operation Grapple was the name of four series of British nuclear weapons tests of early atomic bombs and hydrogen bombs carried out in 1957 and 1958 at Malden Island and Christmas Island in the Pacific Ocean as part of the British hydrogen bomb programme. Nine nuclear explosions were initiated, culminating in the United Kingdom becoming the third recognised possessor of thermonuclear weapons, and the restoration of the nuclear Special Relationship with the United States with the 1958 US-UK Mutual Defence Agreement. Context_9 : USS "Grapple" (ARS-53) is a "Safeguard"-class salvage ship in the United States Navy. Her home port is Norfolk, Virginia. On 13 July 2006 "Grapple" was decommissioned from US Navy service and converted to civilian operation by Military Sealift Command. She was redesignated as USNS "Grapple" (T-ARS 53). Context_10 : The Special Relationship is an unofficial term for the political, diplomatic, cultural, economic, military, and historical relations between the United Kingdom and the United States, which has been used to different degrees in different times in history. It was used in a 1946 speech by Winston Churchill. Although both the UK and US have close relationships with many other nations, the level of cooperation between them in economic activity, trade and commerce, military planning, execution of military operations, nuclear weapons technology, and intelligence sharing has been described as "unparalleled" among major powers. The existence of a "special relationship" has sometimes been described as a myth. US president Barack Obama considered Germany to be his "closest international partner" and said the UK would be at the "back of the queue" in any trade deal with the US if it left the European Union. fact_1 :  Nine nuclear explosions were initiated, culminating in the United Kingdom becoming the third recognised possessor of thermonuclear weapons, and the restoration of the nuclear Special Relationship with the United States with the 1958 US-UK Mutual Defence Agreement. fact_2 :  It was used in a 1946 speech by Winston Churchill. Answer: Winston Churchill
