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.

Q: Passage: The chain of craters has been the subject of several writers and naturalists. Mark Twain visited Mono Basin in the 1860s and wrote about Mono Lake, but did not mention any of the MonoInyo Craters except for the lake's two volcanic islands. He wrote in Roughing It (1872) that the lake was in a "lifeless, hideous desert ..." that was the "loneliest spot on earth ... little graced with the picturesque."
Naturalist John Muir explored the area in 1869. He described the "Mono Desert" as a "... country of wonderful contrasts. Hot deserts bounded by snow-laden mountains,cinders and ashes scattered on glacier-polished pavements,frost and fire working together in the making of beauty. In the lake are several volcanic islands, which show that the waters were once mingled with fire." Muir described the Mono Craters as "... heaps of loose ashes that have never been blest by either rain or snow ..."In the spring of 1881 and the fall of 1882, geologist Israel Russell studied the area as a side-trip during his field research of Lake Lahontan, a now dry lake that covered much of nearby Nevada during the last glacial period. His Quaternary History of the Mono Valley (1889), which included a topographic survey by Willard D. Johnson, was the first thorough scientific description of Mono Lake and its volcanic features.
Russell named the Mono Craters and wrote: "The attention of every one who enters Mono Valley is at once attracted by the soft, pleasing colors of these craters as well as by the symmetry and beauty of their forms. They are exceptional features in the scenery of the region, and are rendered all the more striking by their proximity to the angular peaks and rugged outlines of the High Sierra.".

Q: Passage: Massenet was a fluent and skilful orchestrator, and willingly provided ballet episodes for his operas, incidental music for plays, and a one-act stand-alone ballet for Vienna (Le carillon, 1892). Macdonald remarks that Massenet's orchestral style resembled that of Delibes, "with its graceful movement and bewitching colour", which was highly suited to classical French ballet. The Meditation for solo violin and orchestra, from Thais, is possibly the best known non-vocal piece by Massenet, and appears on many recordings. Another popular stand-alone orchestral piece from the operas is Le dernier sommeil de la Vierge from La Vierge, which has featured on numerous discs since the middle of the 20th century.A Parisian critic, after seeing La grand' tante, declared that Massenet was a symphonist rather than a theatre composer. At the time of the British premiere of Manon in 1885, the critic in The Manchester Guardian, reviewing the work enthusiastically, nevertheless echoed his French confrere's view that the composer was really a symphonist, whose music was at its best when purely orchestral. Massenet took a wholly opposite view of his talents. He was temperamentally unsuited to writing symphonically: the constraints of sonata form bored him. He wrote, in the early 1870s, "What I have to say, musically, I have to say rapidly, forcefully, concisely; my discourse is tight and nervous, and if I wanted to express myself otherwise I would not be myself." His efforts in the concertante field made little mark, but his orchestral suites, colourful and picturesque according to Grove, have survived on the fringes of the repertoire. Other works for orchestra are a symphonic poem, Visions (1891), an Ouverture de Concert (1863) and Ouverture de Phedre (1873). After early attempts at chamber music as a student, he wrote little more in the genre. Most of his early chamber pieces are now lost; three pieces for cello and piano survive.

Q: Passage: Sitting in deckchairs and touring churches is not the holiday 17-year-old Richard wants, but his parents insist on taking him. They are staying at the Tregarron guesthouse in the (fictional) seaside town of Easton in Suffolk. This traditional English boarding house is owned and run by the formidable Miss Wilbraham.
On arrival, Richard befriends Edwin, who is girl-crazy and takes Richard under his wing. In search of girls, Richard and Edwin attend a beach service organized by the local church youth group. After the type of evening one might expect at such a gathering, they enjoy a brief tryst with the twin daughters of the minister.
The following evening another visitor, Julia, agrees to a date with Edwin but only on condition that Anna, her Dutch foreign exchange student friend, can join them. Edwin persuades Richard to join them to make up a foursome. Escaping from his parents on the pretence that the quartet is heading to the youth group's Sausage Sizzle, Richard and his friends visit a local jazz club instead.
Anna attempts to sneak away with some local bikers and Richard gives chase. As Anna rides away on the back of one biker's machine, Richard jumps on the other. The bikes race off into the sand dunes; where Richard and Anna fall off the pillions and into each other's arms. Richard is annoyed but Anna finds the whole affair amusing. Reaching for a handkerchief to clean a cut on his head, Richard also pulls out a condom that he has taken from Edwin's room.
Julia and Edwin, meanwhile, have been to fetch help. Julia's father, Richard's parents and the minister from the youth group set off to rescue Richard and Anna. A lady walking her dog along the beach stumbles across Richard and Anna as it becomes clear that Richard has experienced sexual initiation. The parents and the minister round the corner just in time to catch the teenagers in flagrante delicto.
Both families make excuses to end their holidays early and head for home.
