In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

[EX Q]: Passage: Han Groenewegen worked in the Hague as a freelance architect from 1920 to 1927. Before establishing his own firm, he used to work for the contractor R. Rutgers in the Hague. One of his few works in the Netherlands is the Church of the Holy Heart of Jesus in Schiedam. During the Great Depression, Groenewegen left the Netherlands to established his own new firm in the Dutch East Indies. Many other architects were left for the Indies during the period, e.g. Albert Aalbers. Groenewegen arrived in Medan (on the island of Sumatra) in 1927 to work on the plan for a hospital, the St. Elisabeth's Hospital (1929-1930). He was active in Medan from 1927 to 1942 to work for the Oostkust. Like Schoemaker for the city of Bandung, Gronewegen can be considered as representative of modernist Nieuwe Bouwen in Medan. Among Groenewegen's extensive portfolio in Medan are the expansion of Medan Cathedral (1928), Arnhem Insurance (now Museum Perjuangan TNI, 1930), the Roman Catholic Chinese church in Polonia (1934), Princess Beatrix School (now Immanuel Christian School, 1938), Medan swimming pool (1939), and Oranjeschool (1941). Unlike many of his colleagues however, Groenewegen remained in Indonesia following the independence of the country.

[EX Q]: Passage: 'Robert D. Raiford (December 27, 1927 – November 17, 2017) was an American radio broadcaster and actor, best known for his political/social commentaries delivered during The John Boy and Billy Big Show, a morning radio program heard on stations throughout the American South. He was from Concord, North Carolina and majored in communication at the University of South Carolina. Raiford got his start in broadcasting in 1944 by calling play by play at baseball games. His first real radio job was at WEGO (AM) in Concord, North Carolina. Raiford has appeared in 28 movies, often portraying judge characters. He frequently closed his commentaries with the line "Who says that? I say that!", which also served as the title of a book containing excerpts from these segments. Early in his career, Raiford worked for WTOP radio and WTOP-TV, both CBS News affiliates in Washington, D.C.. His best-known work was a live radio broadcast on WTOP, a CBS Radio affiliate, covering the state funeral of President John F. Kennedy. He also worked at Charlotte radio station WBT. Raiford also hosted a show on WIST, which aired Charlotte's first telephone talk radio format. He later taught Communications at the University of North Carolina at Charlotte. From 1978 to 1986, Raiford was a news anchor and talk show host for Charlotte's NBC television affiliate. It was known as WRET-TV and then WPCQ-TV during his tenure there; it is now WCNC-TV. On the June 9, 2016, episode of The John Boy and Billy Big Show, John Isley ("John Boy") announced that Raiford had retired from the show, due to suffering a stroke the previous August that greatly affected his speech and mobility. Raiford had not delivered any commentaries during the intervening months, choosing to focus on his recovery instead.
 Link Information: The University of South Carolina (USC, UofSC, SC, or simply Carolina) is a public research university in Columbia, South Carolina. Question: In what city did Raiford major in communication?
[EX A]: Answer: Columbia, South Carolina

[EX Q]: Passage: AGRP has been demonstrated to be an inverse agonist of melanocortin receptors, to be specific MC3-R and MC4-R. The melanocortin receptors, MC3-R and MC4-R, are directly linked to metabolism and body weight control. These receptors are activated by the peptide hormone α-MSH (melanocyte-stimulating hormone) and antagonized by the agouti-related protein. Whereas α-MSH acts broadly on most members of the MCR family (with the exception of MC2-R), AGRP is highly specific for only MC3-R and MC4-R. This inverse agonism not only antagonizes the action of melanocortin agonists such as α-MSH but also further decreases the cAMP produced by the affected cells. The exact mechanism by which AgRP inhibits melanocortin-receptor signalling is not completely clear. It has been suggested that Agouti-related protein binds MSH receptors and acts as a competitive antagonist of ligand binding. Studies of Agouti protein in B16 melanoma cells supported this logic. The expression of AgRP in the adrenal gland is regulated by glucocorticoids. The protein blocks α-MSH-induced secretion of corticosterone.
 Link Information: Melanocortin receptor 3 is a protein that in humans is encoded by the MC3R gene. Question: What is the difference between the two melanocortin receptors?
[EX A]:
Answer: Melanocortin receptor 3 is a protein that in humans is encoded by the MC3R gene.
