Question: What is the unit of currency in the part of the United Kingdom where Bloody Friday is located?

<P0-S0> At least twenty bombs exploded in the space of eighty minutes, most within a half hour period. <P0-S1> Most of them were car bombs and most targeted infrastructure, especially the transport network. <P0-S2> Nine people were killed: five civilians, two British soldiers, a Royal Ulster Constabulary (RUC) reservist, and an Ulster Defence Association (UDA) member, while 130 were injured. <P0-S3> The IRA said it sent telephoned warnings at least thirty minutes before each explosion and claimed the security forces wilfully ignored some of the warnings for its own ends. <P0-S4> The security forces denied this and said they were overstretched by the sheer number of bombs and bomb warnings, some of which were hoaxes. <P0-S5> Bloody Friday is the name given to the bombings by the Provisional Irish Republican Army (IRA) in Belfast on 21 July 1972, during the Troubles. <SEP> <P1-S0> the embassy of the united kingdom in beijing (or british embassy, beijing) is the chief diplomatic mission of the united kingdom in the people's republic of china. <P1-S1> it is one of britain's largest overseas embassies. <P1-S2> it is located at "11 guang hua lu", in the chaoyang district. <P1-S3> the current british ambassador to china is barbara woodward. <SEP> <P2-S0> the top reserve currency is generally selected by the banking community for the strength and stability of the economy in which it is used. <P2-S1> thus, as a currency becomes less stable, or its economy becomes less dominant, bankers may over time abandon it for a currency issued by a larger or more stable economy. <P2-S2> this can take a relatively long time, as recognition is important in determining a reserve currency. <P2-S3> for example, it took many years after the united states overtook the united kingdom as the world's largest economy before the dollar overtook the pound sterling as the dominant global reserve currency. <P2-S4> in 1944, when the us dollar was chosen as the world reference currency at bretton woods, it was only the second currency in global reserves. <SEP> <P3-S0> The British Crown dependencies of Guernsey and Jersey produce their own local issues of sterling: the ``Guernsey pound ''and the`` Jersey pound''. <P3-S1> The pound sterling is also used in the Isle of Man (alongside the Manx pound), Gibraltar (alongside the Gibraltar pound), the Falkland Islands (alongside the Falkland Islands pound), Saint Helena and Ascension Island in Saint Helena, Ascension and Tristan da Cunha (alongside the Saint Helena pound). <P3-S2> The Bank of England is the central bank for the pound sterling, issuing its own coins and banknotes, and regulating issuance of banknotes by private banks in Scotland and Northern Ireland. <P3-S3> Banknotes issued by other jurisdictions are not regulated by the Bank of England; local governments use Bank of England notes as backing for local issuance by allowing them to be exchanged 1: 1 at face value. <SEP> <P4-S0> CAMRA maintains a "National Inventory" of historical notability and of architecturally and decoratively notable pubs. <P4-S1> The National Trust owns thirty-six public houses of historic interest including the George Inn, Southwark, London and The Crown Liquor Saloon, Belfast, Northern Ireland.
