Ex Input:
What was Cork City formerly surrounded by?, Context: The city's charter was granted by Prince John, as Lord of Ireland, in 1185. The city was once fully walled, and some wall sections and gates remain today. For much of the Middle Ages, Cork city was an outpost of Old English culture in the midst of a predominantly hostile Gaelic countryside and cut off from the English government in the Pale around Dublin. Neighbouring Gaelic and Hiberno-Norman lords extorted "Black Rent" from the citizens to keep them from attacking the city. The present extent of the city has exceeded the medieval boundaries of the Barony of Cork City; it now takes in much of the neighbouring Barony of Cork. Together, these baronies are located between the Barony of Barrymore to the east, Muskerry East to the west and Kerrycurrihy to the south.

Ex Output:
wall


Ex Input:
Who filed a lawsuit in the same month as Independence Day?, Context: Political interest groups have stated that these laws remove important restrictions on governmental authority, and are a dangerous encroachment on civil liberties, possible unconstitutional violations of the Fourth Amendment. On 30 July 2003, the American Civil Liberties Union (ACLU) filed the first legal challenge against Section 215 of the Patriot Act, claiming that it allows the FBI to violate a citizen's First Amendment rights, Fourth Amendment rights, and right to due process, by granting the government the right to search a person's business, bookstore, and library records in a terrorist investigation, without disclosing to the individual that records were being searched. Also, governing bodies in a number of communities have passed symbolic resolutions against the act.

ACLU

What is the first name of the last president listed in the text, Context: The House of Representatives currently has 59 members elected for a five-year term, 56 members by proportional representation and 3 observer members representing the Armenian, Latin and Maronite minorities. 24 seats are allocated to the Turkish community but remain vacant since 1964. The political environment is dominated by the communist AKEL, the liberal conservative Democratic Rally, the centrist Democratic Party, the social-democratic EDEK and the centrist EURO.KO. In 2008, Dimitris Christofias became the country's first Communist head of state. Due to his involvement in the 2012–13 Cypriot financial crisis, Christofias did not run for re-election in 2013. The Presidential election in 2013 resulted in Democratic Rally candidate Nicos Anastasiades winning 57.48% of the vote. As a result, Anastasiades was sworn in on and has been President since 28 February 2013.

Ex Output:

Nicos
