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.

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.

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

Passage: The first eruptions of Nevado del Ruiz occurred about 1.8 million years ago at the beginning of the Pleistocene epoch. Three primary eruption periods in the history of the massif have been identified: ancestral, older and present. During the ancestral period between one million to two million years ago, a complex of large stratovolcanoes was created. Between 1.0 million and 0.8 million years ago, they partially collapsed, forming large (5–10 km wide) calderas. During the older period, which lasted from 0.8 million to 0.2 million years ago, a new complex of large stratovolcanoes developed (including Older Ruiz, Tolima, Quindio, and Santa Isabel). Once again explosive summit calderas formed from 0.2 million to 0.15 million years ago.The present period began about 150,000 years ago and involved the development of the present volcanic edifice through the emplacement of lava domes made of andesite and dacite (igneous rocks) inside older calderas. During the past 11,000 years, Nevado del Ruiz passed through at least 12 eruption stages, which included multiple slope failures (rock avalanches), pyroclastic flows and lahars leading to partial destruction of the summit domes. During the past several thousand years, eruptions of the volcanoes in the Ruiz–Tolima massif have mostly been small, and the pyroclastic flow deposits have been much less voluminous than during the Pleistocene. Since the volcano's earlier eruptions are not recorded, volcanologists have used tephrochronology to date them.During recorded history, eruptions have consisted primarily of a central vent eruption (in the caldera) followed by an explosive eruption, then lahars. Ruiz's earliest identified Holocene eruption was about 6660 BC, and further eruptions occurred in 1245 BC ± 150 years (dated through radiocarbon dating), about 850 BC, 200 BC ± 100 years, 350 AD ± 300 years, 675 AD ± 50 years, in 1350, 1541 (perhaps), 1570, 1595, 1623, 1805, 1826, 1828 (perhaps),[b] 1829, 1831, 1833 (perhaps),[b] 1845, 1916, December 1984 – March 1985, September 1985 – July 1991, and possibly in April 1994.[b] Many of these eruptions involved a central vent eruption, a flank vent eruption, and a phreatic (steam) explosion. Ruiz is the second-most active volcano in Colombia after Galeras.

Ex Output:
What partially collapsed, forming large (5–10 km wide) calderas?

Passage: Charles-Camille Saint-Saëns (French: [ʃaʁlkamij sɛ̃sɑ̃s]; 9 October 1835 – 16 December 1921) was a French composer, organist, conductor and pianist of the Romantic era. His best-known works include Introduction and Rondo Capriccioso (1863), the Second Piano Concerto (1868), the First Cello Concerto (1872), Danse macabre (1874), the opera Samson and Delilah (1877), the Third Violin Concerto (1880), the Third ("Organ") Symphony (1886) and The Carnival of the Animals (1886).
Saint-Saëns was a musical prodigy; he made his concert debut at the age of ten. After studying at the Paris Conservatoire he followed a conventional career as a church organist, first at Saint-Merri, Paris and, from 1858, La Madeleine, the official church of the French Empire. After leaving the post twenty years later, he was a successful freelance pianist and composer, in demand in Europe and the Americas.
As a young man, Saint-Saëns was enthusiastic for the most modern music of the day, particularly that of Schumann, Liszt and Wagner, although his own compositions were generally within a conventional classical tradition. He was a scholar of musical history, and remained committed to the structures worked out by earlier French composers. This brought him into conflict in his later years with composers of the impressionist and dodecaphonic schools of music; although there were neoclassical elements in his music, foreshadowing works by Stravinsky and Les Six, he was often regarded as a reactionary in the decades around the time of his death.
Saint-Saëns held only one teaching post, at the École de Musique Classique et Religieuse in Paris, and remained there for less than five years. It was nevertheless important in the development of French music: his students included Gabriel Fauré, among whose own later pupils was Maurice Ravel. Both of them were strongly influenced by Saint-Saëns, whom they revered as a genius.

Ex Output:

What are the full names of the people who were influenced by Saint-Saëns?
