Q: 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 This preliminary group was originally made up of talented but amateur members of the court: the sisters Lucrezia and Isabella Bendidio, Leonora Sanvitale, and Vittoria Bentivoglio.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?

A: Lucrezia.

Q: Passage: George Frederic Watts was born in 1817, the son of a London musical instrument manufacturer. His two brothers died in 1823, and his mother in 1826, giving Watts an obsession with death throughout his life. Watts was apprenticed as a sculptor at the age of 10, and by his mid-teens was proficient enough as an artist to be earning a living as a portrait painter. At the age of 18 he gained admission to the Royal Academy schools, although he disliked their methods and his attendance was intermittent. From 1837, Watts was successful enough to devote himself full-time to painting.In 1843 Watts travelled to Italy where he remained for four years. On his return to London he suffered from melancholia, and painted many notably gloomy works. His skills were widely celebrated, and in 1856 he decided to devote himself to portrait painting. His portraits were extremely highly regarded, and in 1867 he was elected to the Royal Academy, at the time the highest honour available to an artist, although he rapidly became disillusioned with its culture. From 1870 onwards he became widely renowned as a painter of allegorical and mythical subjects; by this time, he was one of the most highly regarded artists in the world. In 1881 he added a glass-roofed gallery to his home at Little Holland House, which was open to the public at weekends, further increasing his fame. 
Question: What is the last name of the person gained admission to the Royal Academy schools at age 18?

A: Watts.

Q: Passage: James Barton Longacre (August 11, 1794 – January 1, 1869) was an American portraitist and engraver, and the fourth Chief Engraver of the United States Mint from 1844 until his death. Longacre is best known for designing the Indian Head cent, which entered commerce in 1859, and for the designs of the Shield nickel, Flying Eagle cent and other coins of the mid-19th century.
Longacre was born in Delaware County, Pennsylvania, in 1794. He ran away to Philadelphia at age 12, where he became an apprentice in a bookstore. His artistic talent developed and he was released to apprentice in an engraving firm.  He struck out on his own in 1819, making a name providing illustrations for popular biographical books. He portrayed the leading men of his day; support from some of them, such as South Carolina Senator John C. Calhoun, led to his appointment as chief engraver after the death of Christian Gobrecht in 1844.
In Longacre's first years as a chief engraver, the Philadelphia Mint was dominated by Mint Director Robert M. Patterson and Chief Coiner Franklin Peale. Conflict between Longacre and the two men developed after Congress ordered a new gold dollar and double eagle, with both to be designed by Longacre.  Peale and Patterson nearly had Longacre fired, but the chief engraver was able to convince Treasury Secretary William M. Meredith that he should be retained.  Both Patterson and Peale left the Mint in the early 1850s, ending the conflict.
In 1856, Longacre designed the Flying Eagle cent. When that design proved difficult to strike, Longacre was responsible for the replacement, the Indian Head cent, issued beginning in 1859. Other coins designed by Longacre include the silver and nickel three-cent pieces, the Shield nickel, the pattern Washington nickel, and the two-cent piece.  In 1866–1867, he redesigned the coins of Chile. Longacre died suddenly on New Year's Day 1869; he was succeeded by William Barber.  Longacre's coins are generally well-regarded today, although they have been criticized for lack of artistic advancement. 
Question: What is the last name of the person who was supported by John C. Calhoun?

A:
Longacre.
