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.

Q: Passage: Maiden Castle is an Iron Age hill fort 1.6 miles (2.6 km) south west of Dorchester, in the English county of Dorset. Hill forts were fortified hill-top settlements constructed across Britain during the Iron Age.
The earliest archaeological evidence of human activity on the site consists of a Neolithic causewayed enclosure and bank barrow. In about 1800 BC, during the Bronze Age, the site was used for growing crops before being abandoned. Maiden Castle itself was built in about 600 BC; the early phase was a simple and unremarkable site, similar to many other hill forts in Britain and covering 6.4 hectares (16 acres). Around 450 BC it was greatly expanded and the enclosed area nearly tripled in size to 19 ha (47 acres), making it the largest hill fort in Britain and, by some definitions, the largest in Europe. At the same time, Maiden Castle's defences were made more complex with the addition of further ramparts and ditches. Around 100 BC, habitation at the hill fort went into decline and became concentrated at the eastern end of the site. It was occupied until at least the Roman period, by which time it was in the territory of the Durotriges, a Celtic tribe.
After the Roman conquest of Britain in the 1st century AD, Maiden Castle appears to have been abandoned, although the Romans may have had a military presence on the site. In the late 4th century AD, a temple and ancillary buildings were constructed. In the 6th century AD the hill top was entirely abandoned and was used only for agriculture during the medieval period.
Maiden Castle has provided inspiration for composer John Ireland and authors Thomas Hardy and John Cowper Powys. The study of hill forts was popularised in the 19th century by archaeologist Augustus Pitt Rivers. In the 1930s, archaeologist Mortimer Wheeler and Tessa Verney Wheeler undertook the first archaeological excavations at Maiden Castle, raising its profile among the public. Further excavations were carried out under Niall Sharples, which added to an understanding of the site and repaired damage caused in part by the large number of visitors. Today the site is protected as a Scheduled Ancient Monument and is maintained by English Heritage.

A: Who currently maintains Maiden Castle?

Q: Passage: In 2007, Elderly sold more than 16,000 instruments. The company is a dealer of Martin guitars, as well as other mainstream brands such as Guild and Fender. It sells used Gibson instruments, but not new models as a result of the Gibson lawsuit. Although the bulk of its business comes from guitar sales, the company carries a range of other instruments, such as banjos, ukuleles, mandolins, accordions, concertinas, bouzoukis, sitars, musical saws, and African thumb pianos. Some of the rarer instruments are purchased as collectibles. Elderly is an exclusive retailer of "LunchBox-A-LeLes", ukuleles made from various tin lunch box designs. The journal Bluegrass Unlimited has noted Elderly Instruments for carrying "elite" brands of instruments, such as Paul Duff mandolins, Huss & Dalton acoustic guitars, Stelling banjos, and Nash electric guitars. Elderly was once one of only two American retailers for Apitius Mandolins, now only sold directly. As part of its consignment business, Elderly sells "collections" of instruments that sometimes have rich histories. In September 2006, it placed the Dopyera family's personal collection of resonator instruments up for sale, including some of the Dobro and National brands. The Dopyera family was responsible for founding those companies and innovating the resonator instrument trade.Elderly Instruments carries a number of Martin guitars, including valuable vintage models. In interviews, Werbin frequently mentions Martins made before World War II as especially desirable and "memorable" pieces of the Elderly Instruments inventory. The guitars are sought after by musicians from the bluegrass and other genres. Werbin purchases some of the more valuable or interesting instruments for his personal collection, and has lent them to museums as temporary exhibits.Periodicals for the bluegrass genre such as Bluegrass Canada and Bluegrass Now have featured stories about Elderly and its selection of bluegrass instruments and repair services. Elderly employees maintain connections with the bluegrass industry by attending trade shows such as the International Bluegrass Association Trade Show in Louisville, Kentucky. At these shows, Elderly showcases typical bluegrass instruments, such as banjos, guitars, mandolins, fiddles and resophonic guitars, to musicians and businesspeople. Elderly Instruments staff members have set up organizations such as the "Friends of Bluegrass" to support local bluegrass musicians.Michigan Living magazine noted Elderly's liberal policy regarding the handling of instruments, something Werbin attributes to his difficulty shopping for Martin guitars in New York City in the 1960s. The magazine also notes that customers are encouraged to pick up and play any instrument, an unusual policy for a high-end instrument retailer. Impromptu "jam sessions" are frequent in the store, as customers try out guitars.

A: What is the name of the organization set up to support bluegrass musicians by the employees of the company that sold over 16,000 instruments in 2007?

Q: Passage: A battle-hardened Huntley-Brinkley reporter later said that no military action he had witnessed had ever frightened or disturbed him as much as what he saw in Birmingham. Two out-of-town photographers in Birmingham that day were Charles Moore, who had previously worked with the Montgomery Advertiser and was now working for Life magazine, and Bill Hudson, with the Associated Press. Moore was a Marine combat photographer who was "jarred" and "sickened" by the use of children and what the Birmingham police and fire departments did to them. Moore was hit in the ankle by a brick meant for the police. He took several photos that were printed in Life. The first photo Moore shot that day showed three teenagers being hit by a water jet from a high-pressure firehose. It was titled "They Fight a Fire That Won't Go Out". A shorter version of the caption was later used as the title for Fred Shuttlesworth's biography. The Life photo became an "era-defining picture" and was compared to the photo of Marines raising the U.S. flag on Iwo Jima. Moore suspected that the film he shot "was likely to obliterate in the national psyche any notion of a 'good southerner'." Hudson remarked later that his only priorities that day were "making pictures and staying alive" and "not getting bit by a dog."Right in front of Hudson stepped Parker High School senior Walter Gadsden when a police officer grabbed the young man's sweater and a police dog charged him. Gadsden had been attending the demonstration as an observer. He was related to the editor of Birmingham's black newspaper, The Birmingham World, who strongly disapproved of King's leadership in the campaign. Gadsden was arrested for "parading without a permit", and after witnessing his arrest, Commissioner Connor remarked to the officer, "Why didn't you bring a meaner dog; this one is not the vicious one." Hudson's photo of Gadsden and the dog ran across three columns in the prominent position above the fold on the front page of The New York Times on May 4, 1963.

A:
What was the full name of the photographer that took a photo titled "They Fight a Fire That Won't Go Out"?
