Question: What are the notes issued by the organization that controls monetary policy in the nation that Amin visited twice?

<P0-S0> The U.S. Constitution provides that Congress shall have the power to "borrow money on the credit of the United States". <P0-S1> Congress has exercised that power by authorizing Federal Reserve Banks to issue Federal Reserve Notes. <P0-S2> Those notes are "obligations of the United States" and "shall be redeemed in lawful money on demand at the Treasury Department of the United States, in the city of Washington, District of Columbia, or at any Federal Reserve bank". <P0-S3> Federal Reserve Notes are designated by law as "legal tender" for the payment of debts. <P0-S4> Congress has also authorized the issuance of more than 10 other types of banknotes, including the United States Note and the Federal Reserve Bank Note. <P0-S5> The Federal Reserve Note is the only type that remains in circulation since the 1970s. <SEP> <P1-S0> Monetary policy concerns the actions of a central bank or other regulatory authorities that determine the size and rate of growth of the money supply. <P1-S1> For example, in the United States, the Federal Reserve is in charge of monetary policy, and implements it primarily by performing operations that influence short - term interest rates. <SEP> <P2-S0> william mckinley (january 29, 1843 -- september 14, 1901) was the 25th president of the united states, serving from march 4, 1897 until his assassination in september 1901, six months into his second term. <P2-S1> mckinley led the nation to victory in the spanish -- american war, raised protective tariffs to promote american industry, and maintained the nation on the gold standard in a rejection of free silver (effectively, expansionary monetary policy). <SEP> <P3-S0> during his years in power, amin shifted from being a pro-western ruler enjoying considerable support from israel to being backed by libya's muammar gaddafi, zaire's mobutu sese seko, the soviet union, and east germany. <P3-S1> in 1975, amin became the chairman of the organisation of african unity (oau), a pan-africanist group designed to promote solidarity among african states. <P3-S2> uganda was a member of the united nations commission on human rights from 1977 to 1979. the uk broke diplomatic relations with uganda in 1977, and amin declared that he had defeated the british and added "cbe" to his title for "conqueror of the british empire". <P3-S3> radio uganda then announced his entire title: "his excellency president for life, field marshal alhaji dr. idi amin dada, vc, dso, mc, cbe".as amin's rule progressed into the late 1970s, there was increased unrest against his persecution of certain ethnic groups and political dissidents, along with uganda's very poor international standing due to amin's support for the terrorist hijackers in operation entebbe. <P3-S4> he then attempted to annex tanzania's kagera region in 1978, so tanzanian president julius nyerere had his troops invade uganda; they captured kampala on 11 april 1979 and ousted amin from power. <P3-S5> amin then went into exile, first in libya and then in saudi arabia, where he lived until his death on 16 august 2003. <SEP> <P4-S0> Hafizullah Amin (Pashto/Dari: حفيظ الله امين‎; born 1 August 1929 – 27 December 1979) was an Afghan communist politician during the Cold War. <P4-S1> Amin was born in Paghman and educated at Kabul University, after which he started his career as a teacher. <P4-S2> After a few years in that occupation, he went to the United States to study. <P4-S3> He would visit the United States a second time before moving permanently to Afghanistan, and starting his career in radical politics. <P4-S4> He ran as a candidate in the 1965 parliamentary election but failed to secure a seat. <P4-S5> Amin was the only Khalqist elected to parliament in the 1969 parliamentary election, thus increasing his standing within the party. <P4-S6> He was one of the leading organizers of the Saur Revolution which overthrew the government of Mohammad Daoud Khan. <P4-S7> In 1979 he named himself president, prime minister, and chairman of the Khalq wing. <P4-S8> He has been described as "ruthless" and a "radical Marxist".Amin's short-lived presidency was marked by controversies from beginning to end. <P4-S9> He came to power by disposing of his predecessor Nur Muhammad Taraki and later ordering his death. <P4-S10> Amin made attempts to win support from those who revolted against the communist regime which had begun under Taraki, but his government was unable to solve this problem. <P4-S11> Many Afghans held Amin responsible for the regime's harshest measures, such as ordering thousands of executions. <P4-S12> Thousands of people disappeared without trace during his time in office. <P4-S13> The Soviet Union, which was dissatisfied with Amin, intervened in Afghanistan while invoking the Twenty-Year Treaty of Friendship between Afghanistan and the Soviet Union. <P4-S14> Amin was assassinated by the Soviets on December 27, 1979 as part of Operation Storm-333, having ruled for slightly longer than three months.
