Passage: In Reno, Nevada, Roslyn Tabor is a 30-year-old woman who has just filed for a quickie six-week divorce from her inattentive husband Raymond. After leaving the Washoe County Courthouse, Roslyn ignores Raymond's attempts to talk to her, and meets with her best local friend and landlord, Isabelle Steers, who is also a divorcee. Isabelle takes Roslyn to a bar at Harrah's Reno for drinks to let the reality of her divorce sink in. While there, they meet an aging cowboy named Gaylord 'Gay' Langland and his tow truck driver friend Guido. They invite Roslyn and Isabelle to Guido's old house in the Nevada country to help her forget about the divorce, after Gay tells Roslyn that he is also divorced. They arrive at the unfinished house Guido built for his late wife, who died several years earlier during childbirth. They drink and dance. Roslyn has too much to drink, so Gay drives her home to Reno.
Eventually, Roslyn and Gay move into Guido's half-finished house and start to work on it. One day after breakfast, Gay tells Roslyn how he wishes he were more of a father to his own children, whom he has not seen for some years. Later that afternoon, Roslyn and Gay argue when Gay states his intention to find and kill the rabbits which have been eating the vegetable garden they planted outside Guido's house. 
Question: What are the first names of the people who arrived at the unfinished house?
Roslyn.

Passage: In mid-1917 nine-year-old Frances Griffiths and her mother—both newly arrived in the UK from South Africa—were staying with Frances' aunt, Elsie Wright's mother, in the village of Cottingley in West Yorkshire; Elsie was then 16 years old. The two girls often played together beside the beck (stream) at the bottom of the garden, much to their mothers' annoyance, because they frequently came back with wet feet and clothes. Frances and Elsie said they only went to the beck to see the fairies, and to prove it, Elsie borrowed her father's camera, a Midg quarter-plate. The girls returned about 30 minutes later, "triumphant".Elsie's father, Arthur, was a keen amateur photographer, and had set up his own darkroom. The picture on the photographic plate he developed showed Frances behind a bush in the foreground, on which four fairies appeared to be dancing. Knowing his daughter's artistic ability, and that she had spent some time working in a photographer's studio, he dismissed the figures as cardboard cutouts. Two months later the girls borrowed his camera again, and this time returned with a photograph of Elsie sitting on the lawn holding out her hand to a 1-foot-tall (30 cm) gnome. Exasperated by what he believed to be "nothing but a prank", and convinced that the girls must have tampered with his camera in some way, Arthur Wright refused to lend it to them again. His wife Polly, however, believed the photographs to be authentic.
Towards the end of 1918, Frances sent a letter to Johanna Parvin, a friend in Cape Town, South Africa, where Frances had lived for most of her life, enclosing the photograph of herself with the fairies. On the back she wrote "It is funny, I never used to see them in Africa. It must be too hot for them there."The photographs became public in mid-1919, after Elsie's mother attended a meeting of the Theosophical Society in Bradford. The lecture that evening was on "fairy life", and at the end of the meeting Polly Wright showed the two fairy photographs taken by her daughter and niece to the speaker. As a result, the photographs were displayed at the society's annual conference in Harrogate, held a few months later. There they came to the attention of a leading member of the society, Edward Gardner. One of the central beliefs of theosophy is that humanity is undergoing a cycle of evolution, towards increasing "perfection", and Gardner recognised the potential significance of the photographs for the movement:
the fact that two young girls had not only been able to see fairies, which others had done, but had actually for the first time ever been able to materialise them at a density sufficient for their images to be recorded on a photographic plate, meant that it was possible that the next cycle of evolution was underway. 
Question: What is the first name of the friend that the little girl who took a picture with four fairies?
Johanna.

Passage: Washington, D.C., formally the District of Columbia and commonly referred to as Washington or D.C., is the capital of the United States. Founded after the American Revolution as the seat of government of the newly independent country, Washington was named after George Washington, the first President of the United States and a Founding Father. As the seat of the United States federal government and several international organizations, Washington is an important world political capital. The city is also one of the most visited cities in the world, with more than 20 million tourists annually.The signing of the Residence Act on July 16, 1790, approved the creation of a capital district located along the Potomac River on the country's East Coast. The U.S. Constitution provided for a federal district under the exclusive jurisdiction of the U.S. Congress, and the District is therefore not a part of any state. The states of Maryland and Virginia each donated land to form the federal district, which included the pre-existing settlements of Georgetown and Alexandria. The City of Washington was founded in 1791 to serve as the new national capital. In 1846, Congress returned the land originally ceded by Virginia; in 1871, it created a single municipal government for the remaining portion of the District.
Washington had an estimated population of 702,455 as of July 2018, making it the 20th most populous city in the United States. Commuters from the surrounding Maryland and Virginia suburbs raise the city's daytime population to more than one million during the workweek. Washington's metropolitan area, the country's sixth largest, had a 2017 estimated population of 6.2 million residents.All three branches of the U.S. federal government are centered in the District: Congress (legislative), president (executive), and the U.S. Supreme Court (judicial). Washington is home to many national monuments, and museums, primarily situated on or around the National Mall. The city hosts 177 foreign embassies as well as the headquarters of many international organizations, trade unions, non-profits, lobbying groups, and professional associations, including the World Bank Group, the International Monetary Fund (IMF), the Organization of American States, AARP, the National Geographic Society, the Human Rights Campaign, the International Finance Corporation, and the American Red Cross.
A locally elected mayor and a 13‑member council have governed the District since 1973. However, Congress maintains supreme authority over the city and may overturn local laws. D.C. residents elect a non-voting, at-large congressional delegate to the House of Representatives, but the District has no representation in the Senate. The District receives three electoral votes in presidential elections as permitted by the Twenty-third Amendment to the United States Constitution, ratified in 1961. 
Question: What is the full name of the city for which commuters from Maryland and Virginia suburbs raise its population to more than one million during the workweek?

Washington, D.C.
