Input: Read this: The Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty (c. 1050256 BC). The coinage issued by the central government mint in 119 BC remained the standard coinage of China until the Tang dynasty (618907 AD). The period saw a number of limited institutional innovations. To pay for its military campaigns and the settlement of newly conquered frontier territories, the government nationalized the private salt and iron industries in 117 BC, but these government monopolies were repealed during the Eastern Han period. Science and technology during the Han period saw significant advances, including papermaking, the nautical steering rudder, the use of negative numbers in mathematics, the raised-relief map, the hydraulic-powered armillary sphere for astronomy, and a seismometer employing an inverted pendulum.
Question: In what period did several government monopolies become repealed?

Output: Eastern Han

Input: Read this: Qing dynasty rule in Tibet began with their 1720 expedition to the country when they expelled the invading Dzungars. Amdo came under Qing control in 1724, and eastern Kham was incorporated into neighbouring Chinese provinces in 1728. Meanwhile, the Qing government sent resident commissioners called Ambans to Lhasa. In 1750 the Ambans and the majority of the Han Chinese and Manchus living in Lhasa were killed in a riot, and Qing troops arrived quickly and suppressed the rebels in the next year. Like the preceding Yuan dynasty, the Manchus of the Qing dynasty exerted military and administrative control of the region, while granting it a degree of political autonomy. The Qing commander publicly executed a number of supporters of the rebels and, as in 1723 and 1728, made changes in the political structure and drew up a formal organization plan. The Qing now restored the Dalai Lama as ruler, leading the governing council called Kashag, but elevated the role of Ambans to include more direct involvement in Tibetan internal affairs. At the same time the Qing took steps to counterbalance the power of the aristocracy by adding officials recruited from the clergy to key posts.
Question: What came under Qing control in 1742?

Output: unanswerable

Input: Read this: The following era was marked by instability, as over 1.5 million propertyless Greek refugees from Turkey had to be integrated into Greek society. Because the term "Greeks" in the exchange was based on religion Cappadocian Greeks, Pontian Greeks, and non Greek followers of Greek Orthodoxy were all subject to the exchange as well. Many of these refugees couldn't even speak the language, and were from alien environments, such as the case of the non Greeks and Cappadocians. The refugees also made a dramatic post war population boost, as the amount of refugees was more than a quarter of Greece's prior population. The task was undertaken by settling the Pontians and Cappadocians in the Macedonian mountains, where they would adapt better, and settling the Demotic speakers and non Greeks in the Greek Isles and cities, where they were already adapted to.
Question: Demotic speaking Greek refugees were placed where?

Output: Greek Isles and cities
