Passage: In 1909 Nicaraguan President José Santos Zelaya of the Liberal Party faced opposition from the Conservative Party, led by governor Juan José Estrada of Bluefields who received support from the U.S. government. The United States had limited military presence in Nicaragua, having only one patrolling U.S. Navy ship off the coast of Bluefields, in order to protect the lives and interests of American citizens who lived there. The Conservative Party sought to overthrow Zelaya which led to Estrada's rebellion in December 1909. Two Americans, Leonard Groce and Lee Roy Cannon, were captured and indicted for allegedly joining the rebellion and the laying of mines. Zelaya ordered the execution of the two Americans, which severed U.S. relations. The forces of Chamorro and Nicaraguan General Juan Estrada, each leading conservative revolts against Zelaya's government, had captured three small towns on the border with Costa Rica and were fomenting open rebellion in the capital of Managua. U.S. Naval warships that had been waiting off Mexico and Costa Rica moved into position. The protected cruisers USS Des Moines , USS Tacoma , and collier USS Hannibal  lay in the harbor at Bluefields, Nicaragua, on the Atlantic coast with USS Prairie  en route for Colón, Panama, with 700 Marines. On December 12, 1909, Albany with 280 bluejackets and the gunboat USS Yorktown  with 155, arrived at Corinto, Nicaragua, to join the gunboat USS Vicksburg  with her crew of 155 to protect American citizens and property on the Pacific coast of Nicaragua.
Question: Which happened first, the execution of the two Americans or the USS Yorktown arriving at Corinto?

Passage: In late 1920, the Persian Soviet Socialist Republic in Rasht was preparing to march on Tehran with "a guerrilla force of 1,500 Jangalis, Kurds, Armenians and Azerbaijanis", reinforced by the Bolsheviks' Red Army. This fact, along with various other disorders, mutinies and unrest in the country created "an acute political crisis in the capital." By 1921, the ruling Qajar dynasty of Persia had become corrupt and inefficient. The oil-rich nation was somewhat reliant on the nations of Britain and Russia for military and economic support. Civil wars earlier in the decade had threatened the government, and the only regular military force at the time was the Cossack Brigade. The Qajar shah in 1921 was Ahmad, who had been crowned at the age of eleven. He was considered to be a weak, incompetent ruler, especially after British, Russian and Ottoman occupations of Persia during World War I. In 1911, when the capital city, Tehran, had been seized by the Russians, armed Bakhtiaris tribemen, rather than Iranian regular troops, expelled the invaders. This further diminished the government's reputation, rendering it almost powerless in time of war. Britain, which played a major role in Persia, was dismayed by the Qajar government's inability to rule efficiently. This inefficiency was the background of a power struggle between Britain and Russia, each nation hoping to control Persia. On 14 January 1921, the British General Ironside chose to promote Reza Khan, who had been leading the Tabriz battalion, to lead the entire brigade. About a month later, under British direction, Reza Khan's 3,000-4,000 strong detachment of the Cossack Brigade reached Tehran.
Question: When did Reza Khan did Tehran?

Passage: The services sector made up nearly 50 percent of Paraguay's gross domestic product in 2004 and employed about 19 percent of Paraguay's working population. The importation of goods, especially from Argentina and Brazil, for sale and illegal reexportation creates service industry jobs. The services sector had a moderate growth rate of 0.9 percent from 1990 to 2003. The sector decreased by 7.8 percent in 2002, before rebounding in 2003 with a 1.6 percent growth rate. Instability in the economy and a large black market have hampered development of the formal services sector in Paraguay.
Question: In what year did the service sector have a sharp drop in growth rate?
