In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX Q]: Passage: Curiously, it appears that the Greeks did not "breed" their slaves, at least during the Classical Era, though the proportion of houseborn slaves appears to have been rather large in Ptolemaic Egypt and in manumission inscriptions at Delphi. Sometimes the cause of this was natural; mines, for instance, were exclusively a male domain. On the other hand, there were many female domestic slaves. The example of African slaves in the American South on the other hand demonstrates that slave populations can multiply.Xenophon advised that male and female slaves should be lodged separately, that "…nor children born and bred by our domestics without our knowledge and consent—no unimportant matter, since, if the act of rearing children tends to make good servants still more loyally disposed, cohabiting but sharpens ingenuity for mischief in the bad." The explanation is perhaps economic; even a skilled slave was cheap, so it may have been cheaper to purchase a slave than to raise one. Additionally, childbirth placed the slave-mother's life at risk, and the baby was not guaranteed to survive to adulthood.Houseborn slaves (oikogeneis) often constituted a privileged class. They were, for example, entrusted to take the children to school; they were "pedagogues" in the first sense of the term. Some of them were the offspring of the master of the house, but in most cities, notably Athens, a child inherited the status of its mother. 
Question: What were entrusted to take children to school?
[EX A]: oikogeneis.

[EX 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 able to convince the Treasury Secretary that he should be retained?
[EX A]: Longacre.

[EX Q]: Passage: The promotional clip for "Something" was shot in late October 1969, not long after Lennon had privately announced that he was leaving the band. By this time, the individual Beatles had drawn apart and so the film consisted of separate clips of each Beatle walking around his home, accompanied by his wife, edited together. Harrison's segment shows him and Boyd together in the garden at Kinfauns; in author John Winn's description, Harrison appears "solemn" while Boyd is seen "smiling sweetly" and "sporting leather and fur coats". Winn also comments on the attractiveness of all the wives in contrast to the unkempt appearance of McCartney, especially, who had sunk into depression at the realisation that the Beatles were over. The four segments were edited and compiled into a single film clip by Neil Aspinall. Writing in The New York Times following Aspinall's death in 2008, Allan Kozinn said: "What Mr. Aspinall's idyllic film avoided showing was that the Beatles were at that point barely on speaking terms. In the film, no two Beatles are seen together."In 2015, following restoration overseen by Apple's Jonathan Clyde, the "Something" promo film was included in the Beatles' video compilation 1 and its expanded edition, 1+. Rolling Stone journalist Rob Sheffield comments on the significance of the clip, with regard to the band's history:
[E]ach couple projects a totally different vibe – George and Patti peacocking in their hippie-royalty finery, Paul and Linda on the farm in Scotland with Martha the sheepdog, Ringo and Maureen goofing around on motorbikes, John and Yoko serene in their matching black robes. Each Beatle looks like he's found what he was looking for – but they're heading for four separate futures.
In her review of 1+, for Paste, Gillian Gaar says that with the Beatles' promotional films of their singles, from "Love Me Do" to "Something" (the last one they made during their career), "you can see the development of the promo clip, progressing from a short film that simply served up a straight performance to a piece of work that was striving to be something more artistic.". 
Question: What did John and his wife wear in "Something"?
[EX A]:
matching black robes.
