Question: Other sections of society included the nobility, clergy, and townsmen. Nobles, both the titled nobility and simple knights, exploited the manors and the peasants, although they did not own lands outright but were granted rights to the income from a manor or other lands by an overlord through the system of feudalism. During the 11th and 12th centuries, these lands, or fiefs, came to be considered hereditary, and in most areas they were no longer divisible between all the heirs as had been the case in the early medieval period. Instead, most fiefs and lands went to the eldest son.[R] The dominance of the nobility was built upon its control of the land, its military service as heavy cavalry, control of castles, and various immunities from taxes or other impositions.[S] Castles, initially in wood but later in stone, began to be constructed in the 9th and 10th centuries in response to the disorder of the time, and provided protection from invaders as well as allowing lords defence from rivals. Control of castles allowed the nobles to defy kings or other overlords. Nobles were stratified; kings and the highest-ranking nobility controlled large numbers of commoners and large tracts of land, as well as other nobles. Beneath them, lesser nobles had authority over smaller areas of land and fewer people. Knights were the lowest level of nobility; they controlled but did not own land, and had to serve other nobles.[T]

Question: Between 1847 and 1850, when Blore was building the new east wing, the Brighton Pavilion was once again plundered of its fittings. As a result, many of the rooms in the new wing have a distinctly oriental atmosphere. The red and blue Chinese Luncheon Room is made up from parts of the Brighton Banqueting and Music Rooms with a large oriental chimney piece sculpted by Richard Westmacott. The Yellow Drawing Room has wallpaper supplied in 1817 for the Brighton Saloon, and a chimney piece which is a European vision of how the Chinese chimney piece may appear. It has nodding mandarins in niches and fearsome winged dragons, designed by Robert Jones.

Question: The Basic Law of the Federal Republic of Germany, the federal constitution, stipulates that the structure of each Federal State's government must "conform to the principles of republican, democratic, and social government, based on the rule of law" (Article 28). Most of the states are governed by a cabinet led by a Ministerprasident (Minister-President), together with a unicameral legislative body known as the Landtag (State Diet). The states are parliamentary republics and the relationship between their legislative and executive branches mirrors that of the federal system: the legislatures are popularly elected for four or five years (depending on the state), and the Minister-President is then chosen by a majority vote among the Landtag's members. The Minister-President appoints a cabinet to run the state's agencies and to carry out the executive duties of the state's government.
Is there an answer to this question: Who does Minister-President choose to run state agencies?

Answer: a cabinet

Question: The Mongol Yuan dynasty, through the Bureau of Buddhist and Tibetan Affairs, or Xuanzheng Yuan, ruled Tibet through a top-level administrative department. One of the department's purposes was to select a dpon-chen ('great administrator'), usually appointed by the lama and confirmed by the Mongol emperor in Beijing. The Sakya lama retained a degree of autonomy, acting as the political authority of the region, while the dpon-chen held administrative and military power. Mongol rule of Tibet remained separate from the main provinces of China, but the region existed under the administration of the Yuan dynasty. If the Sakya lama ever came into conflict with the dpon-chen, the dpon-chen had the authority to send Chinese troops into the region.
