In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Question: Passage: The saddest sight was seeing people behind the wire fences on both sides of the land frontier yelling at the top of their voices across the wide dividing space to enquire about the state of relatives, as telephone communications had been cut by the Spaniards. Local housewives with Spanish relatives in the Campo area kept their radios tuned to the nearby Spanish stations for news of family members who were gravely ill. In critical cases the parties concerned would rush to Spain via Tangiers but unfortunately sometimes the patient was dead and buried by the time they arrived. The Spanish authorities would not allow access across the land frontier even on compassionate grounds.
Franco's death in 1975 led to the beginnings of diplomatic movement between Britain and Spain on the Gibraltar issue, though not immediately. Spain applied to join the European Economic Community (EEC) and NATO, for which it needed British support. In 1980, talks between British and Spanish ministers led to the Lisbon Agreement, a statement on co-operation between the two countries which committed them to starting negotiations on Gibraltar's future and lifting the Spanish restrictions on communications with Gibraltar. Although Britain promised to "honour the freely and democratically expressed wishes of the people of Gibraltar", Prime Minister Margaret Thatcher indicated in the House of Commons that sovereignty would be on the table, in a change from the previous policy. However, the border was not reopened due to "technical issues" – code for unresolved issues between the two governments – and the agreement was strongly opposed by many Gibraltarians, who did not wish their sovereignty to be under discussion and objected to the lack of Gibraltarian representatives at the talks. The outbreak of the Falklands War in 1982 caused a further delay. Argentina carried out an unsuccessful sabotage operation, kept secret at the time, that was intended to sink a Royal Navy frigate in Gibraltar's harbour; the saboteurs were captured by the Spanish police in Algeciras before they could carry out their attack. A further agreement was reached in Brussels in 1984 which clarified the Lisbon Agreement and required that Britain allow Spaniards to live and work in Gibraltar, which they would have the right to do anyway as EEC citizens. The border was finally fully reopened on 4–5 February 1985.

Answer: In what city did a further agreement occur that clarified the statement of co-operation issues in 1980 between British and Spanish ministers?


Question: Passage: Teenaged brothers Zach and Gray Mitchell visit Jurassic World, a dinosaur theme park at the original Jurassic Park site on Isla Nublar. Their aunt, Claire Dearing, is the operations manager. Claire assigns her assistant, Zara, as the boys' guide but they soon evade her. Elsewhere on the island, U.S. Navy veteran and ethologist Owen Grady has been training and researching four Velociraptors. Based on the raptors' ability to follow commands, Vic Hoskins, the head of InGen Security, believes the animals can be weaponized, an idea Owen and his assistant Barry strongly oppose.
Prior to its opening, Claire and park owner Simon Masrani inspect the park's newest attraction, Indominus rex, a genetically-engineered dinosaur created by geneticist Dr. Henry Wu. Masrani tasks Owen with evaluating the enclosure. Owen warns Claire the Indominus lacks social skills, making it more dangerous and unpredictable. When it appears the Indominus has escaped, Owen and two park workers enter the enclosure. The Indominus, which can camouflage itself and mask its heat signature, suddenly appears. Owen survives the attack, but it kills the other two men before escaping into the island's interior. Owen tells Masrani to have the Indominus killed; to protect his company's investment, Masrani instead dispatches a specialized unit to subdue it with non-lethal weaponry. After most of the unit is wiped out, Claire orders the evacuation of the island's northern sector.

Answer: Who does the boy's aunt have look after her nephews?


Question: Passage: While on a hunting trip on Loyalsock Creek north of the park in 1850, brothers Elijah and Clemuel Ricketts were frustrated at having to spend the night on a hotel's parlor floor. In 1851 or 1853 they bought 5,000 acres (2,000 ha), including what is now Lake Ganoga and some of the park, as their own hunting preserve, and built a stone house on the lake shore by 1852 or 1855. The stone house served as their lodge and as a tavern; it was known as "Ricketts Folly" for its isolated location in the wilderness. Clemuel died in 1858 and Elijah bought his share of the land and house. The Ricketts family was not aware of the glens and their waterfalls until about 1865, when they were discovered by two guests from the stone house who went fishing and wandered down Kitchen Creek.Elijah's son Robert Bruce Ricketts, for whom the park is named, joined the Union Army as a private at the outbreak of the American Civil War and rose through the ranks to become a colonel in the artillery. After the war, R. Bruce Ricketts returned to Pennsylvania and in 1869 began purchasing the land around the lake from his father. By 1873 he controlled or owned 66,000 acres (27,000 ha), and eventually this grew to more than 80,000 acres (32,000 ha), including the glens and waterfalls and most of the park.While the stone house had served as a home and inn since its construction, in 1872 R. Bruce Ricketts built a three-story wooden addition north of the house. The addition used lumber from a sawmill Ricketts and his partners operated from 1872 to 1875, about 0.5 miles (0.8 km) southeast of the stone house. The North Mountain House hotel opened in 1873; Ricketts' brother Frank, for whom a park waterfall is named, managed it from then until 1898. Many of the hotel's guests were Ricketts' friends and relations, who arrived after school let out in June and stayed all summer until school resumed in September. In 1876 and 1877, Ricketts ran the first summer school in the United States at his house and hotel; one of the teachers was Joseph Rothrock, later known as the "Father of Forestry" in Pennsylvania.

Answer:
What is the last name of the person who died in 1858?
