Input: Read this: In the 11th century and the 12th century, the princes and their retinues, which were a mixture of Slavic and Scandinavian elites, dominated the society of Kievan Rus'. Leading soldiers and officials received income and land from the princes in return for their political and military services. Kievan society lacked the class institutions and autonomous towns that were typical of Western European feudalism. Nevertheless, urban merchants, artisans and labourers sometimes exercised political influence through a city assembly, the veche (council), which included all the adult males in the population. In some cases, the veche either made agreements with their rulers or expelled them and invited others to take their place. At the bottom of society was a stratum of slaves. More important was a class of tribute-paying peasants, who owed labour duty to the princes. The widespread personal serfdom characteristic of Western Europe did not exist in Kievan Rus'.
Question: What was the group called that owed labour duty to the princes?

Output: tribute-paying peasants

QUES: Today, Greeks are the majority ethnic group in the Hellenic Republic, where they constitute 93% of the country's population, and the Republic of Cyprus where they make up 78% of the island's population (excluding Turkish settlers in the occupied part of the country). Greek populations have not traditionally exhibited high rates of growth; nonetheless, the population of Greece has shown regular increase since the country's first census in 1828. A large percentage of the population growth since the state's foundation has resulted from annexation of new territories and the influx of 1.5 million Greek refugees after the 1923 population exchange between Greece and Turkey. About 80% of the population of Greece is urban, with 28% concentrated in the city of Athens

QUES: Formally, a "database" refers to a set of related data and the way it is organized. Access to these data is usually provided by a "database management system" (DBMS) consisting of an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data). The DBMS provides various functions that allow entry, storage and retrieval of large quantities of information and provides ways to manage how that information is organized.

Question: In April 1979, young students protested against Bokassa's decree that all school attendees would need to buy uniforms from a company owned by one of his wives. The government violently suppressed the protests, killing 100 children and teenagers. Bokassa himself may have been personally involved in some of the killings. In September 1979, France overthrew Bokassa and "restored" Dacko to power (subsequently restoring the name of the country to the Central African Republic). Dacko, in turn, was again overthrown in a coup by General Andre Kolingba on 1 September 1981.
Try to answer this question if possible: In what year was Dacko overthrown by Bokassa?
Answer: unanswerable

Context and question: Since all contact between the wrestlers must cease if any part of the body is touching, or underneath, the ropes, many wrestlers will attempt to break submission holds by deliberately grabbing the bottom ropes. This is called a "rope break", and it is one of the most common ways to break a submission hold. Most holds leave an arm or leg free, so that the person can tap out if they want. Instead, they use these free limbs to either grab one of the ring ropes (the bottom one is the most common, as it is nearest the wrestlers, though other ropes sometimes are used for standing holds such as Chris Masters' Master Lock) or drape their foot across, or underneath one. Once this has been accomplished, and the accomplishment is witnessed by the referee, the referee will demand that the offending wrestler break the hold, and start counting to five if the wrestler does not. If the referee reaches the count of five, and the wrestler still does not break the hold, they are disqualified.
When must contact stop between wrestlers?
