Question: In 2018, who was elected mayor of the city out of which the Sea Nymph sailed?

full_context: Document 1: San Diego: The members of the city council are each elected from single member districts within the city. The mayor and city attorney are elected directly by the voters of the entire city. The mayor, city attorney, and council members are elected to four-year terms, with a two-term limit. Elections are held on a non-partisan basis per California state law; nevertheless, most officeholders do identify themselves as either Democrats or Republicans. In 2007, registered Democrats outnumbered Republicans by about 7 to 6 in the city, and Democrats currently (as of 2015[update]) hold a 5-4 majority in the city council. The current mayor, Kevin Faulconer, is a Republican.
Document 2: Tuvalu: In 1892 Captain Davis of the HMS Royalist reported on trading activities and traders on each of the islands visited. Captain Davis identified the following traders in the Ellice Group: Edmund Duffy (Nanumea); Jack Buckland (Niutao); Harry Nitz (Vaitupu); John (also known as Jack) O'Brien (Funafuti); Alfred Restieaux and Emile Fenisot (Nukufetau); and Martin Kleis (Nui). During this time, the greatest number of palagi traders lived on the atolls, acting as agents for the trading companies. Some islands would have competing traders while dryer islands might only have a single trader.
Document 3: Marshall Islands: On 28 April 2015, the Iranian navy seized the Marshall Island-flagged MV Maersk Tigris near the Strait of Hormuz. The ship had been chartered by Germany's Rickmers Ship Management, which stated that the ship contained no special cargo and no military weapons. The ship was reported to be under the control of the Iranian Revolutionary Guard according to the Pentagon. Tensions escallated in the region due to the intensifying of Saudi-led coalition attacks in Yemen. The Pentagon reported that the destroyer USS Farragut and a maritime reconnaissance aircraft were dispatched upon receiving a distress call from the ship Tigris and it was also reported that all 34 crew members were detained. US defense officials have said that they would review U.S. defense obligations to the Government of the Marshall Islands in the wake of recent events and also condemned the shots fired at the bridge as "inappropriate". It was reported in May 2015 that Tehran would release the ship after it paid a penalty.
Document 4: 2017 Minneapolis mayoral election: No candidate achieved a majority in the first round of ballot counting on election night. Jacob Frey was declared the winner the next day after several rounds of vote tabulations.
Document 5: 2018 San Francisco mayoral special election: Eight candidates qualified to appear on the ballot, and a ninth qualified as a write - in.

Document 6: 2018 Kansas gubernatorial election: On August 7, 2018, Kobach appeared headed for victory over incumbent Governor Jeff Colyer in the Republican gubernatorial primary by an initial margin of 191 votes. By August 9, 2018, his lead stood at 121 votes, but discrepancies in some counties needed resolution, and provisional and absentee ballots may not have been counted in some counties. Democratic Senator Laura Kelly easily won the Democratic nomination. Independent Greg Orman, who finished second in the 2014 U.S. Senate race against incumbent Republican Pat Roberts, is running for governor, again as an independent candidate.
Document 7: Christina Olague: Olague was appointed to the post by mayor Ed Lee in the wake of her predecessor Ross Mirkarimi's election to be sheriff of San Francisco. However, she was defeated by challenger London Breed in the San Francisco Board of Supervisors elections, 2012. She was the first openly bisexual person to serve as a San Francisco Supervisor.
Document 8: Marshall Islands: Captain John Charles Marshall and Thomas Gilbert visited the islands in 1788. The islands were named for Marshall on Western charts, although the natives have historically named their home "jolet jen Anij" (Gifts from God). Around 1820, Russian explorer Adam Johann von Krusenstern and the French explorer Louis Isidore Duperrey named the islands after John Marshall, and drew maps of the islands. The designation was repeated later on British maps.[citation needed] In 1824 the crew of the American whaler Globe mutinied and some of the crew put ashore on Mulgrave Island. One year later, the American schooner Dolphin arrived and picked up two boys, the last survivors of a massacre by the natives due to their brutal treatment of the women.:2
Document 9: Seattle: Seattle's political culture is very liberal and progressive for the United States, with over 80% of the population voting for the Democratic Party. All precincts in Seattle voted for Democratic Party candidate Barack Obama in the 2012 presidential election. In partisan elections for the Washington State Legislature and United States Congress, nearly all elections are won by Democrats. Seattle is considered the first major American city to elect a female mayor, Bertha Knight Landes. It has also elected an openly gay mayor, Ed Murray, and a socialist councillor, Kshama Sawant. For the first time in United States history, an openly gay black woman was elected to public office when Sherry Harris was elected as a Seattle city councillor in 1991. The majority of the current city council is female, while white men comprise a minority.
Document 10: Samoa: Mission work in Samoa had begun in late 1830 by John Williams, of the London Missionary Society arriving in Sapapali'i from The Cook Islands and Tahiti. According to Barbara A. West, "The Samoans were also known to engage in ‘headhunting', a ritual of war in which a warrior took the head of his slain opponent to give to his leader, thus proving his bravery." However, Robert Louis Stevenson, who lived in Samoa from 1889 until his death in 1894, wrote in A Footnote to History: Eight Years of Trouble in Samoa, "… the Samoans are gentle people."
Document 11: Marshall Islands: The battle in the Marshall Islands caused irreparable damage, especially on Japanese bases. During the American bombing, the islands' population suffered from lack of food and various injuries. U.S. attacks started in mid-1943, and caused half the Japanese garrison of 5,100 people in the atoll Mili to die from hunger by August 1945.
Document 12: Marshall Islands: A number of vessels visiting the islands were attacked and their crews killed. In 1834, Captain DonSette and his crew were killed. Similarly, in 1845 the schooner Naiad punished a native for stealing with such violence that the natives attacked the ship. Later that year a whaler's boat crew were killed. In 1852 the San Francisco-based ships Glencoe and Sea Nymph were attacked and everyone aboard except for one crew member were killed. The violence was usually attributed as a response to the ill treatment of the natives in response to petty theft, which was a common practice. In 1857, two missionaries successfully settled on Ebon, living among the natives through at least 1870.:3
Document 13: History of Cuba: On 25 December 1894, three ships, the Lagonda, the Almadis and the Baracoa, set sail for Cuba from Fernandina Beach, Florida, loaded with armed men and supplies. Two of the ships were seized by U.S. authorities in early January, who also alerted the Spanish government, but the proceedings went ahead. The insurrection began on 24 February 1895, with uprisings all across the island. In Oriente the most important ones took place in Santiago, Guantánamo, Jiguaní, San Luis, El Cobre, El Caney, Alto Songo, Bayate and Baire. The uprisings in the central part of the island, such as Ibarra, Jagüey Grande and Aguada, suffered from poor co-ordination and failed; the leaders were captured, some of them deported and some executed. In the province of Havana the insurrection was discovered before it got off and the leaders detained. Thus, the insurgents further west in Pinar del Río were ordered to wait.
Document 14: Seattle: Like most parts of the United States, government and laws are also run by a series of ballot initiatives (allowing citizens to pass or reject laws), referenda (allowing citizens to approve or reject legislation already passed), and propositions (allowing specific government agencies to propose new laws/tax increases directly to the people). Federally, Seattle is part of Washington's 7th congressional district, represented by Democrat Jim McDermott, elected in 1988 and one of Congress's liberal members. Ed Murray is currently serving as mayor.
Document 15: 2017 San Antonio mayoral election: On May 6, 2017, the city of San Antonio, Texas held an election to choose the next mayor of San Antonio.
