Passage: When originally used in Olney, it is unknown what music, if any, accompanied the verses written by John Newton. Contemporary hymnbooks did not contain music and were simply small books of religious poetry. The first known instance of Newton's lines joined to music was in A Companion to the Countess of Huntingdon's Hymns (London, 1808), where it is set to the tune "Hephzibah" by English composer John Husband. Common meter hymns were interchangeable with a variety of tunes; more than twenty musical settings of "Amazing Grace" circulated with varying popularity until 1835 when William Walker assigned Newton's words to a traditional song named "New Britain", which was itself an amalgamation of two melodies ("Gallaher" and "St. Mary") first published in the Columbian Harmony by Charles H. Spilman and Benjamin Shaw (Cincinnati, 1829). Spilman and Shaw, both students at Kentucky's Centre College, compiled their tunebook both for public worship and revivals, to satisfy "the wants of the Church in her triumphal march". Most of the tunes had been previously published, but "Gallaher" and "St. Mary" had not. As neither tune is attributed and both show elements of oral transmission, scholars can only speculate that they are possibly of British origin. A manuscript from 1828 by Lucius Chapin, a famous hymn writer of that time, contains a tune very close to "St. Mary", but that does not mean that he wrote it."Amazing Grace", with the words written by Newton and joined with "New Britain", the melody most currently associated with it, appeared for the first time in Walker's shape note tunebook Southern Harmony in 1847. It was, according to author Steve Turner, a "marriage made in heaven ... The music behind 'amazing' had a sense of awe to it. The music behind 'grace' sounded graceful. There was a rise at the point of confession, as though the author was stepping out into the open and making a bold declaration, but a corresponding fall when admitting his blindness." Walker's collection was enormously popular, selling about 600,000 copies all over the U.S. when the total population was just over 20 million. Another shape note tunebook named The Sacred Harp (1844) by Georgia residents Benjamin Franklin White and Elisha J. King became widely influential and continues to be used.Another verse was first recorded in Harriet Beecher Stowe's immensely influential 1852 anti-slavery novel Uncle Tom's Cabin. Three verses were emblematically sung by Tom in his hour of deepest crisis. He sings the sixth and fifth verses in that order, and Stowe included another verse not written by Newton that had been passed down orally in African American communities for at least 50 years. It was originally one of between 50 and 70 verses of a song titled "Jerusalem, My Happy Home" that first appeared in a 1790 book called A Collection of Sacred Ballads:. 
Question: What are the first names of the people who were students at Kentucky's Centre College?
Benjamin.

Passage: At the court in Ferrara, a collection of ladies skilled in music inspired the composer Luzzasco Luzzaschi and caught the Duke's interest. This group, which led to the formation of the concerto delle donne, performed within the context of the Duke's musica secreta, a regular series of chamber music concerts performed for an exclusive audience. This preliminary group was originally made up of talented but amateur members of the court: the sisters Lucrezia and Isabella Bendidio, Leonora Sanvitale, and Vittoria Bentivoglio. They were joined by bass Giulio Cesare Brancaccio, who was specifically brought to the court in 1577 for his singing ability. The preliminary ensemble was active throughout the 1570s, and its membership solidified in 1577. Only later did professionals replace these original singers.
The Duke did not announce the creation of a professional, all-female ensemble; instead, the group infiltrated and gradually dominated the musica secreta, so that after the dismissal of Brancaccio for insubordination in 1583, no more male members of the musica secreta were hired. Even when Brancaccio was performing with the consort it was referred to as a ladies' ensemble, because women singing together was the most exciting aspect of the group. This new ensemble, the concerto delle donne, was created by Alfonso in part to amuse his young new wife, Margherita Gonzaga d'Este (she was only fourteen when they wed in 1579), and in part to help the Duke achieve his artistic goals for the court. According to Grana, a contemporary correspondent, "Signora Machiavella [Lucrezia], Signora Isabella, and Signora Vittoria have abandoned the field, having lost the backing of Luzzaschi". The first recorded performance by the professional ladies was on November 20, 1580; by carnival season in 1581, they were performing together regularly.This new "consort of ladies" was viewed as an extraordinary and novel phenomenon; most witnesses did not connect the second period of the concerto delle donne with the group of ladies who sang in the musica secreta. Today, however, the earlier group is viewed as a crucial part of the creation and development of the social and vocal genre of the concerto delle donne. 
Question: What were the first names of the two sisters in the original preliminary group?
Lucrezia.

Passage: A cave family called the Croods survives a natural disaster, due to the overprotective nature of their stubborn and stern patriarch named Grug. The only one who questions the family's sheltered life is his teenaged daughter Eep, who frequently disobeys her father's orders out of curiosity, which he finds dangerous. Grug and Eep, along with her mother and his wife Ugga, her grandmother Gran, and her younger brother and sister, Thunk and Sandy, face time sheltered in their cave home.
Eep sneaks out when she sees what she discovers to be a torch of fire, and she encounters an inventive modern human boy named Guy and his pet sloth Belt. He warns her of an impending apocalypse and offers to take her with him, but concerned for her family, Eep stays, getting a shell horn from him to blow in case she needs his help. Reuniting with her frantic family, she tries to tell them what Guy told her, but fearing things that are "different" and "new", they destroy her horn.
A massive earthquake then destroys their home, and to avoid carnivores and omnivores, they descend down into a tropical forest that lay hidden behind their cave all the time. Encountering a "Macawnivore", a brightly colored feline that Gran dubs "Chunky", the family flees him until he is scared off by swarms of piranhakeets that devour a ground whale. Using another horn, Eep calls to Guy who rescues them from the birds with his fire. After a great deal of confusion regarding their first contact with fire, Grug imprisons Guy in a log until he can guide them somewhere safe. Guy suggests the Croods go to a mountain where there are caves because the Crood family desires a cave. Grug refuses at first, but he decides to go with the promise of a cave. The other Croods were worried that they would get tired and bicker, but Grug doesn't listen. 
Question: Who does the modern human boy warn?

Eep.
