Passage: The yellowhammer is a conspicuous, vocal and formerly common country bird, and has attracted human interest. Yellowham Wood and Yellowham Hill, near Dorchester, both derive their names from the bird. Robbie Burns' poem "The Yellow, Yellow Yorlin'" gets its title from a Scottish name for the yellowhammer, which is given an obvious sexual connotation: I met a pretty maid, an' unto her I said,/ "I wad fain fin' your yellow, yellow yorlin'." More factual descriptions of the bird and its behaviour can be found in John Clare's "The Yellowhammer's Nest" and "The Yellowhammer", whose final lines read:
Enid Blyton helped to popularise the bird's song as "little bit of bread and no cheese" in books such as The Ship of Adventure and Five Go Off in a Caravan, and wrote a poem called "The Yellow-hammer".
Beethoven's student, Carl Czerny, and biographer Anton Schindler, both suggested that the composer got the idea for the first four notes of his 5th symphony from the yellowhammer's call, although it is more likely that the opening of the 4th Piano Concerto was actually the work in question. Beethoven also used the yellowhammer theme in two piano sonatas, no. 21 in C major (the "Waldstein", Op.53) and No. 23 in F minor (the "Appassionata", Op.57).Olivier Messiaen often used birdsong as an inspiration for his music, and the yellowhammer features in Chronochromie, Catalogue d'oiseaux, La fauvette des jardins and Méditations sur le mystère de la Sainte Trinité, appearing in four movements of the last piece.An old legend links the yellowhammer to the Devil. Its tongue was supposed to bear a drop of his blood, and the intricate pattern on the eggs was said to carry a concealed, possibly evil, message; these satanic associations sometimes led to the persecution of the bird. The unusual appearance of the eggs also led to "scribble lark", an old name for the bird. 
Question: What are the names of the two piano sonatas Beethoven used the yellowhammer theme in?
no. 21 in C major.

Passage: Forty-eight Non-Indian people visited Yosemite Valley in 1855, including San Francisco writer James Mason Hutchings and artist Thomas Ayres. Hutchings wrote an article about his experience that was published in the July 12, 1855, issue of the Mariposa Gazette and Ayres' sketch of Yosemite Falls was published in late 1855; four of his drawings were presented in the lead article of the July 1856 and initial issue of Hutchings' Illustrated California Magazine. The article and illustrations created tourist interest in Yosemite and eventually led to its protection.Ayres returned in 1856 and visited Tuolumne Meadows in the area's high country. His highly detailed angularly exaggerated artwork and his written accounts were distributed nationally and an art exhibition of his drawings was held in New York City.
Hutchings took photographer Charles Leander Weed to Yosemite Valley in 1859; Weed took the first photographs of the valley's features, which were presented to the public in a September exhibition held in San Francisco. Hutchings published four installments of "The Great Yo-semite Valley" from October 1859 to March 1860 in his magazine and re-published a collection of these articles in his Scenes of Wonder and Curiosity in California, which remained in print into the 1870s.
Carleton Watkins exhibited his 17 by 22 in (43 by 56 cm) Yosemite views at the 1867 Paris International Exposition.Photographer Ansel Adams made his first trip to Yosemite in 1916; his photographs of the valley made him famous in the 1920s and 1930s. Adams willed the originals of his Yosemite photos to the Yosemite Park Association, and visitors can still buy direct prints from his original negatives. The studio in which the prints are sold was established in 1902 by artist Harry Cassie Best.Milton and Houston Mann opened a toll road to Yosemite Valley in 1856, up the South Fork of the Merced River. They charged the then considerable sum of two dollars per person until the road was bought by Mariposa County, after which it became free.
In 1856, settler Galen Clark discovered the Mariposa Grove of giant sequoia at Wawona, an indigenous encampment in what is now the southwestern part of the park. Clark completed a bridge over the South Fork of the Merced River in 1857 at Wawona for traffic headed toward Yosemite Valley and provided a way station for travelers on the road the Mann brothers built to the valley.Simple lodgings, later called the Lower Hotel, were completed soon afterward; the Upper Hotel, later renamed Hutchings House and eventually known as Cedar Cottage, was opened in 1859. In 1876, the more substantial Wawona Hotel was built to serve tourists visiting the nearby grove of big trees and those on their way to Yosemite Valley. Aaron Harris opened the first campground business in Yosemite in 1876. 
Question: What is the last name of the person in whose magazine four installments of "The Great Yo-semite Valley" were published?
Hutchings.

Passage: 1974, the present. Dorothy Yates lives with her husband Edmund in an isolated farmhouse in Haslemere, Surrey. They have just been released from a mental institution to which they were committed in 1957 after it was found Dorothy was a cannibal who killed and partially ate at least six people. It is later revealed that her cannibalism can be understood as an attempt to cope with a childhood trauma when she found out that she had eaten parts of her pet rabbit that her parents had cooked and served as dinner. Although her husband Edmund was convicted, it is later revealed that he only faked his dementia in order to remain with his wife. He is a truly devoted husband who loves his wife dearly and does not take part in the actual acts of murder in 1957 and in the present, only helping in covering them up. Now, it seems as if Dorothy has had a severe relapse. She secretly lures lonely young people to her home, promising tea and a tarot card reading, only with the sessions ending with a violent murder and "feast".  
Jackie, Edmund's daughter by previous marriage, lives in London but secretely visits her dad and stepmum at night to bring her parcels containing animal brain, thereby implicitly feigning to commit murders for her so as to contain Dorothy's murderous urges. At the same time, Jackie tries to control her 15-year-old stepsister Debbie, Dorothy's actual daughter that she and Edmund had shortly before being committed to the asylum. Debbie has been recently thrown out of the orphanage. She now stays with Jackie and rides with her boyfriend Alec, head of a violent biker gang. Debbie incites Alec to start a fight with a barman in one of London's hip nightclubs because he denied her liquor due to her being underage. When they get thrown out, the bike gang later ambush and assault the barman with a chain but leave when spotted. Debbie, however, decides to stay behind and hides the body in the trunk of a car before the police arrive. 
Question: Whose boyfirend is the head of a biker gang?

Debbie.
