Input: Read this: The existence of the early state of Shu was poorly recorded in the main historical records of China. It was, however, referred to in the Book of Documents as an ally of the Zhou. Accounts of Shu exist mainly as a mixture of mythological stories and historical legends recorded in local annals such as the Chronicles of Huayang compiled in the Jin dynasty (265420), with folk stories such as that of Emperor Duyu () who taught the people agriculture and transformed himself into a cuckoo after his death. The existence of a highly developed civilization with an independent bronze industry in Sichuan eventually came to light with an archaeological discovery in 1986 at a small village named Sanxingdui in Guanghan, Sichuan. This site, believed to be an ancient city of Shu, was initially discovered by a local farmer in 1929 who found jade and stone artefacts. Excavations by archaeologists in the area yielded few significant finds until 1986 when two major sacrificial pits were found with spectacular bronze items as well as artefacts in jade, gold, earthenware, and stone. This and other discoveries in Sichuan contest the conventional historiography that the local culture and technology of Sichuan were undeveloped in comparison to the technologically and culturally "advanced" Yellow River valley of north-central China. The name Shu continues to be used to refer to Sichuan in subsequent periods in Chinese history up to the present day.
Question: What did Emperor Duyu transform himself into after his death?

Output: a cuckoo

Input: Read this: Burke was not merely presenting a peace agreement to Parliament; rather, he stepped forward with four reasons against using force, carefully reasoned. He laid out his objections in an orderly manner, focusing on one before moving to the next. His first concern was that the use of force would have to be temporary, and that the uprisings and objections to British governance in America would not be. Second, Burke worried about the uncertainty surrounding whether Britain would win a conflict in America. "An armament", Burke said, "is not a victory". Third, Burke brought up the issue of impairment; it would do the British Government no good to engage in a scorched earth war and have the object they desired (America) become damaged or even useless. The American colonists could always retreat into the mountains, but the land they left behind would most likely be unusable, whether by accident or design. The fourth and final reason to avoid the use of force was experience; the British had never attempted to rein in an unruly colony by force, and they did not know if it could be done, let alone accomplished thousands of miles away from home. Not only were all of these concerns reasonable, but some turned out to be prophetic the American colonists did not surrender, even when things looked extremely bleak, and the British were ultimately unsuccessful in their attempts to win a war fought on American soil.

Input: Read this: From the 1970s onward, Stuart Hall's pioneering work, along with that of his colleagues Paul Willis, Dick Hebdige, Tony Jefferson, and Angela McRobbie, created an international intellectual movement. As the field developed it began to combine political economy, communication, sociology, social theory, literary theory, media theory, film/video studies, cultural anthropology, philosophy, museum studies and art history to study cultural phenomena or cultural texts. In this field researchers often concentrate on how particular phenomena relate to matters of ideology, nationality, ethnicity, social class, and/or gender.[citation needed] Cultural studies has a concern with the meaning and practices of everyday life. These practices comprise the ways people do particular things (such as watching television, or eating out) in a given culture. This field studies the meanings and uses people attribute to various objects and practices. Specifically, culture involves those meanings and practices held independently of reason. Watching television in order to view a public perspective on a historical event should not be thought of as culture, unless referring to the medium of television itself, which may have been selected culturally; however, schoolchildren watching television after school with their friends in order to "fit in" certainly qualifies, since there is no grounded reason for one's participation in this practice. Recently, as capitalism has spread throughout the world (a process called globalization), cultural studies has begun[when?] to analyze local and global forms of resistance to Western hegemony.[citation needed] Globalization in this context can be defined as western civilization in other ways, it undermines the cultural integrity of other culture and it is therefore repressive, exploitative and harmful to most people in different places.
