Input: Consider Input: 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?

Output: Longacre.


Input: Consider Input: Passage: The crew of a malfunctioning alien cargo ship make an emergency landing on Earth. This draws the attention of four sexually-frustrated humans in a nearby park: Oliver and Prudence (a mild-mannered professional and his highly-strung fiancée), Willy (a bumbling shop assistant) and Cliff (a middle-aged man).
Oliver, Prudence, Willy and Cliff wander into the ship and encounter three aliens resembling human women: engineer Partha, nurse Cosia and the captain, known only as Skipper. Willy inadvertently drops some pornographic magazines that he has recently bought. The aliens mistake some approaching cows for a hostile force and hurriedly take off, despite warnings from the long-suffering computer about the precarious state of the ship's systems. Resuming their original course, they study their guests in detail. Fascinated by the anatomy of the males, they decide to sell them to a zoo for exotic lifeforms on a distant planet. They also debate the significance of the acts depicted in Willy's magazines. Partha is particularly keen to emulate them and enthusiastically has sex with Cliff.
Skipper, Cosia and Partha subject the males to a series of tests to learn more about their abilities. Oliver and Cliff fail miserably. However, Willy, looking for his magazines, beats Skipper's combat simulation by unknowingly evading her attacks, causing her to collapse with exhaustion and infer that he is a stronger being. While conducting a physical examination on Willy, Cosia discovers that his biology is more advanced than anything known to their species; encouraging Cosia with exaggerated claims about his sexual prowess, Willy loses his virginity to her. Later, he passes an intelligence test by a fluke and has sex with Partha. 
Question: Who decides to sell people to a zoo for exotic lifeforms on a distant planet?

Output: Skipper.


Input: Consider Input: Passage: Ethiopian historians such as Taddesse Tamrat (1935–2013) and Sergew Hable Sellassie have argued that modern Ethiopian studies were an invention of the 17th century and originated in Europe. Tamrat considered Carlo Conti Rossini's 1928 Storia d'Etiopia a groundbreaking work in Ethiopian studies. The philosopher Messay Kebede likewise acknowledged the genuine contributions of Western scholars to the understanding of Ethiopia's past. But he also criticized the perceived scientific and institutional bias that he found to be pervasive in Ethiopian-, African-, and Western-made historiographies on Ethiopia. Specifically, Kebede took umbrage at E. A. Wallis Budge's translation of the Kebra Nagast, arguing that Budge had assigned a South Arabian origin to the Queen of Sheba although the Kebra Nagast itself did not indicate such a provenience for this fabled ruler. According to Kebede, a South Arabian extraction was contradicted by biblical exegetes and testimonies from ancient historians, which instead indicated that the Queen was of African origin. Additionally, he chided Budge and Ullendorff for their postulation that the Aksumite civilization was founded by Semitic immigrants from South Arabia. Kebede argued that there is little physical difference between the Semitic-speaking populations in Ethiopia and neighboring Cushitic-speaking groups to validate the notion that the former groups were essentially descendants of South Arabian settlers, with a separate ancestral origin from other local Afroasiatic-speaking populations. He also observed that these Afroasiatic-speaking populations were heterogeneous, having interbred with each other and also assimilated alien elements of both uncertain extraction and negroid origin. 
Question: What are the two groups Kebede argued were were essentially descendants of South Arabian settlers, with a separate ancestral origin from other local Afroasiatic-speaking populations?


Output: Semitic-speaking populations in Ethiopia.
