Question: When was the Good Friday Agreement established? Passage 1:He testified as an expert witness about Russian interference in the 2016 United States elections, in a March 30, 2017 hearing before the United States Senate Select Committee on Intelligence. His testimony before the Senate Intelligence Committee was well received, and made multiple headlines. Slate referred to him in a headline as: "Clint Watts, Testifier Extraordinaire", and "The star of March's Senate Intelligence Committee hearing". CNN profiled him after the testimony in a piece "Russia investigation: Who is Clint Watts", where it was noted he gained knowledge in the field of Russian cyber hacking methods, after himself being a target in 2015 following his "Trolling for Trump" article; the FBI notified the Foreign Policy Research Institute of the attack. Salon compared his testimony "follow the trail of dead Russians" to John Dean's statement about "a cancer on the presidency". This phrase in testimony by Watts was highlighted by the media, including CBS News, The American Interest, and The Oregonian. U.S. Senator Ron Wyden found the comment important to his investigation. Mark Shields of PBS NewsHour found his testimony "compelling", and CNN called it "blistering". Jennifer Rubin wrote for The Washington Post that his testimony "laid out the most comprehensive look at the array of tools Russia used to influence our election". After his testimony, he appeared on NBC's Meet the Press and explained ways the U.S. can better respond to cyberwarfare.
Passage 2:The Irish government under outgoing Taoiseach Enda Kenny expressed concerns that a parliamentary deal between a British government and the DUP could put the Northern Ireland peace process at risk, a view also expressed by Sinn Fein politicians Gerry Adams and Gerry Kelly, Labour MP Yvette Cooper and former Downing Street Director of Communications Alastair Campbell. This opinion was, however, rejected by the Conservative leadership and former Secretary of State for Northern Ireland, Theresa Villiers, as well as by former Labour minister Caroline Flint who suggested that Gordon Brown may have sought an agreement with the DUP in 2010. The Conservative peer and former UUP First Minister of Northern Ireland, David Trimble, described claims that an agreement would put the peace process at risk as "scaremongering". On 13 June former Conservative Prime Minister John Major publicly urged May to govern without DUP support and not pursue a deal, on the grounds that an agreement could "damage" the "fragile" Northern Ireland peace process, suggesting the government must remain 'impartial'. Major himself had an agreement with the Unionist MPs of the UUP when in power and during peace negotiations in Northern Ireland, though not with the more hardline and socially-conservative DUP. On 15 June Sinn Fein's Gerry Adams met with Theresa May, telling her that he thought she was in breach of the Good Friday Agreement. This has been disputed by one of the UUP's negotiators for the Belfast Agreement.

Passage 2:Lerdorf was born on Disko Island in Greenland and moved to Denmark in his early years. Lerdorf's family moved to Canada from Denmark in 1980, and later moved to King City, Ontario in 1983. He graduated from King City Secondary School in 1988, and in 1993 he graduated from the University of Waterloo with a Bachelor of Applied Science in Systems Design Engineering. He contributed to the Apache HTTP Server and he added the LIMIT clause to the mSQL DBMS. A variant of this LIMIT clause had already been around for a decade in mainframe relational database management systems (like Oracle Rdb running on VAX/VMS, formerly from Digital Equipment Corporation), but apparently it had not yet been picked up by the emerging PC-based databases. It was later adapted by several other SQL-compatible DBMS. He released the first version of PHP in 1995.

The group has also traveled to South Africa (2016) and the American Southwest (2017). The group won the 1997 ICCA competition and notable performances include the 1996 Olympic Games, the White House, with 10-time Grammy award winner Bobby McFerrin in 2005 and 2019, with Seal in 2009, with Joan Baez in 2019, annually at Stanford Graduation Baccalaureate, and their sold-out 25th Anniversary Show in Bing Concert Hall in 2015.
