In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

Input: Consider Input: Passage: Although originally proposed to the French space agency CNES, it was considered too complex and expensive for a single national programme. Its acceptance within the European Space Agency's scientific programme, in 1980, was the result of a lengthy process of study and lobbying. The underlying scientific motivation was to determine the physical properties of the stars through the measurement of their distances and space motions, and thus to place theoretical studies of stellar structure and evolution, and studies of galactic structure and kinematics, on a more secure empirical basis. Observationally, the objective was to provide the positions, parallaxes, and annual proper motions for some 100,000 stars with an unprecedented accuracy of 0.002arcseconds, a target in practice eventually surpassed by a factor of two. The name of the space telescope, "Hipparcos" was an acronym for High Precision Parallax Collecting Satellite, and it also reflected the name of the ancient Greek astronomer Hipparchus, who is considered the founder of trigonometry and the discoverer of the precession of the equinoxes (due to the Earth wobbling on its axis).
Link Information: when ESRO was merged with ELDO. ESA had ten founding member states: Belgium, Denmark, France, West Germany, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom. Answer: Belgium

Output: What countries make up the agency that Hipparcos was accepted to after being considered too complex for CNES?

Input: Consider Input: Passage: Anne Beloff was born in 1921 in Hampstead to Simon Beloff and Marie Katzin. Her parents were of RussianJewish background, and her siblings included the historian Max Beloff, Baron Beloff, the psychologist John Beloff, the journalist Nora Beloff, and the politician Renee Soskin. She earned a degree in chemistry from University College London in 1942 before completing a PhD in the biochemistry of skin burns with Rudolph Peters at the University of Oxford. She visited Harvard Medical School in 1946 to perform research and returned to the UK in 1948. In the same year she married Ernst Boris Chain, a biochemist who had won the Nobel Prize in Physiology or Medicine in 1945, and moved with him to Rome.
Link Information: Harvard Medical School (HMS) is the graduate medical school of Harvard University. It is located in the Longwood neighborhood of Boston, Massachusetts. Answer: Boston

Output: In what city is the university where Beloff traveled to in 1946 to perform research?

Input: Consider Input: Passage: A son of Daud Khan, a Georgian prince and convert to Islam, by a concubine, he was born Khosro Mirza and brought up Muslim at the Persian court by eunuchs alongside young slave recruits. An intelligent and resolute in his decisions, he soon attracted the attention of Shah Abbas I of Safavid who appointed him, in 1618, a darugha (prefect) of the capital Isfahan. From 1625 to 1626, he took part in suppression of the Georgian opposition: he commanded a right flank at the victorious Battle of Marabda and saved part of the Persian troops from a complete disaster at the Battle of Ksani. In 1626, Khosro Mirza was recalled from Georgia and appointed the commander of the Shah's elite gholam corps (qollar-aghasi) three years later. In 1629, Abbas, lying on a deathbed, urged him to protect a grandson and heir Sam Mirza, the future Shah Safi, whom Khosro served faithfully. In 1630, he led a Persian army which defeated the Ottoman forces and captured Baghdad. In the early 1630s, he took part in sidelining and destruction of the Undiladze family, also of Georgian origin, who had dominated the Safavid court for years. Afterwards, he was sent to suppress the opposition of Georgians who had managed to unite the eastern regions of Kartli and Kakheti under Teimuraz I for a brief period of 1630-1633. Teimuraz was joined by a surviving Undiladze, Daud Khan. For his loyalty, Shah Safi appointed him as the new vali of Kartli, and granted him the name of Rostam Khan (Rostom, , in Georgian transliteration). Rostom then came to Georgia with a large Persian army commanded by his fellow Georgian Rustam Khan. He soon took control of Kartli and garrisoned all major fortresses with Persian forces, bringing them, however, under his tight control. His willingness to cooperate with his suzerain won for Kartli a larger degree of autonomy. A period of relative peace and prosperity ensued, with the cities and towns being revived, many deserted areas repopulated and commerce flourished. Although Muslim, Rostom helped to restore a major Georgian Orthodox cathedral of Living Pillar (Svetitskhoveli) at Mtskheta, and patronised Christian culture. However, Islam and Persian habits predominated at his court. He ruthlessly crushed an opposition of local nobles, putting to death the catholicos Eudemus I of Georgia, and invaded, in 1648, Kakheti, forcing Teimuraz to flee to Imereti (western Georgia).
