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.

[EX Q]: Passage: In London, Grainger's charm, good looks and talent (with some assistance from the local Australian community) ensured that he was quickly taken up as a pianist by wealthy patrons. He was soon performing in concerts in private homes. The Times critic reported after one such appearance that Grainger's playing "revealed rare intelligence and a good deal of artistic insight".  In 1902 he was presented by the socialite Lillith Lowrey to Queen Alexandra, who thereafter frequently attended his London recitals. Lowrey, 20 years Grainger's senior, traded patronage and contacts for sexual favours – he termed the relationship a "love-serve job". She was the first woman with whom he had sex; he later wrote of this initial encounter that he had experienced "an overpowering landslide" of feeling, and that "I thought I was about to die. If I remember correctly, I only experienced fear of death. I don't think that any joy entered into it".In February 1902 Grainger made his first appearance as a piano soloist with an orchestra, playing Tchaikovsky's first piano concerto with the Bath Pump Room Orchestra. In October of that year he toured Britain in a concert party with Adelina Patti, the Italian-born opera singer. Patti was greatly taken by the young pianist and prophesied a glorious career for him. The following year he met the German-Italian composer and pianist Ferruccio Busoni. Initially the two men were on cordial terms (Busoni offered to give Grainger lessons free of charge) and, as a result, Grainger spent part of the 1903 summer in Berlin as Busoni's pupil.  However, the visit was not a success; as Bird notes, Busoni had expected "a willing slave and adoring disciple", a role Grainger was not willing to fulfill. Grainger returned to London in July 1903; almost immediately he departed with Rose on a 10-month tour of Australia, New Zealand and South Africa, as a member of a party organised by the Australian contralto Ada Crossley.
[EX A]: What is the full name of the person that Grainger was presented to?

[EX Q]: 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 A]: What partially collapsed, forming large (5–10 km wide) calderas?

[EX Q]: Passage: The highly fictionalised story sees 'Schani' dismissed from his job in a bank. He puts together a group of unemployed musicians who wangle a performance at Dommayer's cafe. The audience is minimal, but when two opera singers, Carla Donner and Fritz Schiller, visit whilst their carriage is being repaired, the music attracts a wider audience.
Strauss is caught up in a student protest; he and Carla Donner avoid arrest and escape to the Vienna Woods, where he is inspired to create the waltz 'Tales from the Vienna Woods'.
Carla asks Strauss for some music to sing at an aristocratic soiree and this leads to the composer receiving a publishing contract. He's on his way, and he can now marry Poldi Vogelhuber, his sweetheart. But the closeness of Strauss and Carla Donner during rehearsals of operettas, attracts comment, not least from Count Hohenfried, Donner's admirer.
Poldi remains loyal to Strauss and the marriage is a long one. He is received by the Kaiser Franz Joseph I of Austria (whom he unknowingly insulted in the aftermath of the student protests) and the two stand before cheering crowds on the balcony of Schönbrunn.
[EX A]:
What is the name of the person who creates "Tales from Vienna Woods?"?
