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.
question:
Passage: Daphne Blake is a high school student who has a semi-popular web show discussing the possibility of aliens and supernatural occurrences. Velma Dinkley is Daphne's supportive yet critical online friend, who believes there is a logical explanation for everything. After Velma web chats Daphne following her latest episode, she reveals to Velma that her parents will be moving to Ridge Valley, where Velma currently goes to high school.
After having a perfect morning at home, Daphne embarks on her first day at Ridge Valley High. She quickly meets Carol, her senior advisor, who shows her the school's expansive collection of advanced technology from Bloom Innovative, a famous technology company. While on her tour, Daphne runs into Velma, who does not speak to her. Later that afternoon, Daphne sees a student named Spencer walk into an open locker as if he were in a trance.
At home, Daphne's father reveals that he has sheltered Daphne all her life, going to extreme lengths to follow her around everywhere in an attempt to make Daphne's life "perfect". Shocked and frustrated at her father, Daphne vows to do everything on her own without her father's assistance. The next day, Daphne gets into a heated argument with Velma over their science project, which Velma intentionally sabotaged. The argument results in the girls getting sent to the principal's office, who puts them on "the best couch for conflict resolution". The couch helps the girls put aside their differences, and Velma reveals she was protecting Daphne because she knew of the strange happenings at the school. Daphne and Velma vow to solve the mystery of the disappearing students.
answer:
What are the full names of the friends who go to Ridge Valley High?

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.
answer:
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?


question:
Passage: Perhaps influenced by van Eyck's Madonna in the Church, Lochner closely detailed the fall and gradient of light. According to the art historian Brigitte Corley, the clothes of "protagonists change their hues in delicate reaction to the influx of light, reds being transformed through a symphony of pink tonalities to a dusty greyish white, greens to a warm pale yellow, and lemon shading through oranges to a saturated red". Lochner employed the notion of supernatural illumination not just from van Eyck, but also from von Soest's Crucifixion, where light emanating from Christ dissolves around John's red robe, as yellows rays eventually become white. There is a real possibility that a number of the faces of saints are modelled on historical persons, i.e. as donor portraits of the commissioners and their wives. Figures fitting this theory include St Ursula and St Gereon panels from the City Saints altarpiece.Unlike the painters in the Low Countries, Lochner was not so concerned with delineating perspective; his pictures are often set in shallow space, while his backgrounds give little indication of distance and often dissolve into solid gold. Thus, and given his harmonious colour schemes, Lochner is usually described as one of the last exponents of the International Gothic. This is not to say his paintings lack contemporary northern sophistication; his arrangements are often innovative. The worlds he paints are hushed, according to Snyder, achieved with the symmetry of subdued use of colour and the often repeated stylistic element of circles. Angels form circles around the heavenly figures; the heavenly figures' heads are highly circular and they wear round haloes. According to Snyder, the viewer is slowly "drawn into empathy with the revolving forms".Because of the paucity of surviving attributed works, it is difficult to detect any evolution in Lochner's style. Art historians are unsure if his style became progressively more or less influenced by Netherlandish art. Recent dendrochronological examination of attributed works indicate that his development was not linear, suggesting that the more advanced Presentation in the Temple is of 1445, predating the more Gothic Saints panels now divided between London and Cologne.
answer:

What are the names of the two saints who are among the number of faces for which there is a real possibility they are modelled on historical persons?
