[EX Q]: Passage: The Tibetan Empire emerged in the 7th century, but with the fall of the empire the region soon divided into a variety of territories. The bulk of western and central Tibet (Ü-Tsang) was often at least nominally unified under a series of Tibetan governments in Lhasa, Shigatse, or nearby locations; these governments were at various times under Mongol and Chinese overlordship. The eastern regions of Kham and Amdo often maintained a more decentralized indigenous political structure, being divided among a number of small principalities and tribal groups, while also often falling more directly under Chinese rule after the Battle of Chamdo; most of this area was eventually incorporated into the Chinese provinces of Sichuan and Qinghai. The current borders of Tibet were generally established in the 18th century. Question: Which Chinese provinces used to be the eastern part of Tibet?
[EX A]: Sichuan and Qinghai

[EX Q]: Passage: By 1885, a new summer retreat was contemplated. That summer, the Bells had a vacation on Cape Breton Island in Nova Scotia, spending time at the small village of Baddeck. Returning in 1886, Bell started building an estate on a point across from Baddeck, overlooking Bras d'Or Lake. By 1889, a large house, christened The Lodge was completed and two years later, a larger complex of buildings, including a new laboratory, were begun that the Bells would name Beinn Bhreagh (Gaelic: beautiful mountain) after Bell's ancestral Scottish highlands.[N 21] Bell also built the Bell Boatyard on the estate, employing up to 40 people building experimental craft as well as wartime lifeboats and workboats for the Royal Canadian Navy and pleasure craft for the Bell family. An enthusiastic boater, Bell and his family sailed or rowed a long series of vessels on Bras d'Or Lake, ordering additional vessels from the H.W. Embree and Sons boatyard in Port Hawkesbury, Nova Scotia. In his final, and some of his most productive years, Bell split his residency between Washington, D.C., where he and his family initially resided for most of the year, and at Beinn Bhreagh where they spent increasing amounts of time. Question: What did the Bells call the house completed in 1889?
[EX A]: The Lodge

[EX Q]: Passage: After the Seleucid defeat at the Battle of Magnesia in 190 BC, the kings of Sophene and Greater Armenia revolted and declared their independence, with Artaxias becoming the first king of the Artaxiad dynasty of Armenia in 188. During the reign of the Artaxiads, Armenia went through a period of hellenization. Numismatic evidence shows Greek artistic styles and the use of the Greek language. Some coins describe the Armenian kings as "Philhellenes". During the reign of Tigranes the Great (95–55 BC), the kingdom of Armenia reached its greatest extent, containing many Greek cities including the entire Syrian tetrapolis. Cleopatra, the wife of Tigranes the Great, invited Greeks such as the rhetor Amphicrates and the historian Metrodorus of Scepsis to the Armenian court, and - according to Plutarch - when the Roman general Lucullus seized the Armenian capital Tigranocerta, he found a troupe of Greek actors who had arrived to perform plays for Tigranes. Tigranes' successor Artavasdes II even composed Greek tragedies himself. Question: What years did Tigranes the Great reign?
[EX A]:
95–55 BC
