Input: Copyright infringement
In the U.S., copyright infringement is sometimes confronted via lawsuits in civil court, against alleged infringers directly, or against providers of services and software that support unauthorized copying. For example, major motion-picture corporation MGM Studios filed suit against P2P file-sharing services Grokster and Streamcast for their contributory role in copyright infringement. In 2005, the Supreme Court ruled in favor of MGM, holding that such services could be held liable for copyright infringement since they functioned and, indeed, willfully marketed themselves as venues for acquiring copyrighted movies. The MGM v. Grokster case did not overturn the earlier Sony decision, but rather clouded the legal waters; future designers of software capable of being used for copyright infringement were warned.

Who did MGM studios file a lawsuit against?
Output: Grokster and Streamcast

Input: Tajikistan
Tajikistan is landlocked, and is the smallest nation in Central Asia by area. It lies mostly between latitudes 36° and 41° N (a small area is north of 41°), and longitudes 67° and 75° E (a small area is east of 75°). It is covered by mountains of the Pamir range, and more than fifty percent of the country is over 3,000 meters (9,800 ft) above sea level. The only major areas of lower land are in the north (part of the Fergana Valley), and in the southern Kofarnihon and Vakhsh river valleys, which form the Amu Darya. Dushanbe is located on the southern slopes above the Kofarnihon valley.

Where is Dushanbe located?
Output: on the southern slopes above the Kofarnihon valley

Input: Late Middle Ages
The changes brought about by these developments have led many scholars to view this period as the end of the Middle Ages and beginning of modern history and early modern Europe. However, the division is somewhat artificial, since ancient learning was never entirely absent from European society. As a result there was developmental continuity between the ancient age (via classical antiquity) and the modern age. Some historians, particularly in Italy, prefer not to speak of the late Middle Ages at all, but rather see the high period of the Middle Ages transitioning to the Renaissance and the modern era.

Historians from what country in particular do not refer to the Late Middle Ages?
Output: Italy

Input: Han dynasty
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. 1050–256 BC). The coinage issued by the central government mint in 119 BC remained the standard coinage of China until the Tang dynasty (618–907 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.

In what period did several government monopolies become repealed?
Output:
Eastern Han
