Passage: The museum's founder Sigurður Hjartarson worked as a teacher and principal for 37 years, teaching history and Spanish at Reykjavík's Hamrahlid College for the last 26 years before his retirement. As a child, he owned a bull's pizzle, which was given to him to use as a cattle whip. He began collecting penises after a friend heard the story of the bull's penis in 1974 and gave him four new ones, three of which Sigurður gave to friends. Acquaintances at whaling stations began bringing him whale penises as well, and the collection grew from there, expanding through donations and acquisitions from various sources around Iceland.The organs of farm animals came from slaughterhouses, while fishermen supplied those of pinnipeds and the smaller whales. The penises of larger whales came from commercial whaling stations, although this source dried up after the International Whaling Commission implemented a global ban on commercial whaling in 1986. Sigurður was able to continue to collect whale penises by harvesting them from the 12–16 whales that fall victim to stranding on the Icelandic coast each year. He also obtained the penis of a polar bear shot by fishermen who found the animal drifting on drift ice off the Westfjords.Sigurður was assisted by his family, though not without some occasional embarrassment. His daughter Þorgerður recalls that she was once sent to a slaughterhouse to collect a specimen but arrived just as the workers were taking a lunch break: "Someone asked, 'What's in the basket?' I had to say, 'I'm collecting a frozen goat penis.' After that I said, 'I will never collect for you again.'" According to Sigurður, "Collecting penises is like collecting anything. You can never stop, you can never catch up, you can always get a new one, a better one."
The collection was at first housed in Sigurður's office at the college until he retired from his teaching job. He decided, more as a hobby than a job, to put it on public display in Reykjavík and was awarded a grant from the city council of ISK 200,000 to support the opening of a museum in August 1997. By 2003, it was attracting 5,200 visitors a year, of which 4,200 were from abroad. He put the museum up for sale in 2003, but also offered it to the city of Reykjavík as a gift. However, he was unsuccessful in obtaining financial support from the state or city. When he retired in 2004, he could no longer afford the rent on the museum's premises. 
Question: What was offered to the city of Reykjavík as a gift?
the museum.

Passage: Time-Life also wanted to expand, as its existing space in 1 Rockefeller Plaza had become insufficient by 1953. In August of that year, Rockefeller Center Inc. bought a tract of land on the west side of Sixth Avenue between 50th and 51st streets. Rockefeller Center's managers originally wanted to build an extra NBC studio or a Ford vehicle showroom on the site. However, they changed their minds once they saw Time Inc.'s expansion needs: the company wanted to have its headquarters in a single building. As they would outgrow their existing space in 1 Rockefeller Plaza by 1954, the company would have to move elsewhere. Not wanting to lose Time Inc.'s tenancy, the complex's managers hired Harrison & Abramovitz, composed of Wallace Harrison and Max Abramovitz, to create plans for a building on the newly acquired plot that could house both NBC and Time. NBC later dropped out of the deal because its CEO, David Sarnoff, dissented.In 1956, two years after the demolition of the Center Theatre, officials announced the construction of a new tower, the Time-Life Building, on the western side of Sixth Avenue between 50th and 51st Streets. The 500-foot (150 m), $7 million building ($97.2 in 2018 dollars) would include connections to the existing passageway system and to the Roxy Theater directly to its west. The tower would rise as a 48-story slab, with a plaza to the east and an eight-story annex along its western and northern sides. One of Rockefeller Center's subsidiaries, Westprop Inc., bought the air rights to the original Roxy Theater located next door so that the new tower could conform to the Zoning Resolution of 1916. Time Inc. and Rockefeller Center formed a joint venture, Rock-Time Inc., which would share the tower's rent income between them. Construction on the Time-Life Building's steelwork started in April 1958, and the structure topped out in November of that year. The cornerstone of the building was laid in June 1959, after the building's structure had been completed, and the first tenants began moving into the tower in December 1959.During this time, plans called for Rockefeller Center to expand northward. Rockefeller Center, Uris Buildings Corporation, and Webb and Knapp formed another joint venture, Rock-Uris Corp., to construct a hotel to the west of 75 Rockefeller Center. However, Webb and Knapp faced monetary shortages, and the joint venture found that a hotel was not the most profitable use of the land. The joint venture instead decided to construct a glass-and-concrete 43-story office building on the site, with connections to the complex's underground concourse. In 1961, the building was named after Sperry Corporation, which leased eight floors in the future building. The planned hotel was moved to another site two blocks north, on the west side of Sixth Avenue between 53rd Streets. This became the New York Hilton at Rockefeller Center, which opened in 1963. The hotel's name was misleading because it was located outside the complex and not connected to the underground mall. The mall could not be extended anyway because the 53rd Street subway was in the way. Further expansion of Rockefeller Center on the west side of Sixth Avenue, between the Hilton and the new Time-Life Building, was not possible because the Equitable Life Assurance Society had built a tower in between the two properties. 
Question: What building's cornerstone was laid in June 1959?
the Time-Life Building.

Passage: The film takes place in Minnesota, in 1990. Detective Bruce Kenner investigates the case of John Gray, who admits to sexually abusing his 17-year-old daughter Angela but has no recollection of the abuse. They seek the help of Professor Kenneth Raines to use recovered-memory therapy on John Gray to retrieve his memories, and come to suspect that their colleague Detective George Nesbitt is involved. They detain him but fail to find evidence against him. Detectives suspect a satanic cult is involved because of Angela's testimony, in which Angela says that she was abused by people in masks and someone took pictures of it.
Bruce and Kenneth meet Angela's estranged brother Roy Gray to inquire about why he left the house. Using the regression technique on him, he recalls hooded figures entering his room while he was young. Bruce and Kenneth suspect Roy's grandmother, Rose Gray, has some involvement but find nothing after a search of her house.
Meanwhile, Bruce begins having nightmares involving satanic rituals. Angela tells him that the cult is out to kill her as she has shown her demonic mark to him and that he is in danger as well. She tells him that her mother received miscellaneous calls and saw strange figures staring at her in the street before she met with an accident. Bruce starts to experience the same things and his nightmares increase in intensity. 
Question: What is the name of John Gray's mother?

Rose Gray.
