Given the task definition, example input & output, solve the new input case.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input case for you: 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.
Output:
What is the full name of the person who became an apprentice in a bookstore?
