Problem: Josip Broz Tito:

The event was significant not only for Yugoslavia and Tito, but also for the global development of socialism, since it was the first major split between Communist states, casting doubt on Comintern's claims for socialism to be a unified force that would eventually control the whole world, as Tito became the first (and the only successful) socialist leader to defy Stalin's leadership in the COMINFORM. This rift with the Soviet Union brought Tito much international recognition, but also triggered a period of instability often referred to as the Informbiro period. Tito's form of communism was labeled "Titoism" by Moscow, which encouraged purges against suspected "Titoites'" throughout the Eastern bloc.

What name refers to the period of instability during the rift between Tito and the USSR?
---
A: Informbiro


Problem: The city of Rome had a place called the Campus Martius ("Field of Mars"), which was a sort of drill ground for Roman soldiers. Later, the Campus became Rome's track and field playground. In the campus, the youth assembled to play and exercise, which included jumping, wrestling, boxing and racing.[citation needed] Equestrian sports, throwing, and swimming were also preferred physical activities.[citation needed] In the countryside, pastimes included fishing and hunting.[citation needed] Board games played in Rome included dice (Tesserae or Tali), Roman Chess (Latrunculi), Roman Checkers (Calculi), Tic-tac-toe (Terni Lapilli), and Ludus duodecim scriptorum and Tabula, predecessors of backgammon. Other activities included chariot races, and musical and theatrical performances.[citation needed]
What was the name of the area in which youth played and exercised?

Answer: Campus Martius


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Greek surnames were widely in use by the 9th century supplanting the ancient tradition of using the father’s name, however Greek surnames are most commonly patronymics. Commonly, Greek male surnames end in -s, which is the common ending for Greek masculine proper nouns in the nominative case. Exceptionally, some end in -ou, indicating the genitive case of this proper noun for patronymic reasons. Although surnames in mainland Greece are static today, dynamic and changing patronymic usage survives in middle names where the genitive of father's first name is commonly the middle name (this usage having been passed on to the Russians). In Cyprus, by contrast, surnames follow the ancient tradition of being given according to the father’s name. Finally, in addition to Greek-derived surnames many have Latin, Turkish and Italian origin.
What letter of the alphabet do most of the last names the men of France end with?
A: unanswerable


Context and question: Kathmandu is located in the northwestern part of the Kathmandu Valley to the north of the Bagmati River and covers an area of 50.67 km2 (19.56 sq mi). The average elevation is 1,400 metres (4,600 ft) above sea level. The city is directly bounded by several other municipalities of the Kathmandu valley: south of the Bagmati by Lalitpur Sub-Metropolitan City (Patan) with which it today forms one urban area surrounded by a ring road, to the southwest by Kirtipur Municipality and to the east by Madyapur Thimi Municipality. To the north the urban area extends into several Village Development Committees. However, the urban agglomeration extends well beyond the neighboring municipalities, e. g. to Bhaktapur and just about covers the entire Kathmandu valley.
What river is south of Kathmandu?
Answer: Bagmati


Question: Greenwich Mean Time (GMT) is an older standard, adopted starting with British railways in 1847. Using telescopes instead of atomic clocks, GMT was calibrated to the mean solar time at the Royal Observatory, Greenwich in the UK. Universal Time (UT) is the modern term for the international telescope-based system, adopted to replace "Greenwich Mean Time" in 1928 by the International Astronomical Union. Observations at the Greenwich Observatory itself ceased in 1954, though the location is still used as the basis for the coordinate system. Because the rotational period of Earth is not perfectly constant, the duration of a second would vary if calibrated to a telescope-based standard like GMT or UT—in which a second was defined as a fraction of a day or year. The terms "GMT" and "Greenwich Mean Time" are sometimes used informally to refer to UT or UTC.
Is there an answer to this question: The term calibrated is also used informally to refer to what? 

Answer: unanswerable


Problem: Carnival:

Some of the best-known traditions, including carnal parades and masquerade balls, were first recorded in medieval Italy. The carnival of Venice was, for a long time, the most famous carnival (although Napoleon abolished it in 1797 and only in 1979 was the tradition restored). From Italy, Carnival traditions spread to Spain, Portugal and France and from France to New France in North America. From Spain and Portugal it spread with colonization to the Caribbean and Latin America. In the early 19th century in the German Rhineland and Southern Netherlands, the weakened medieval tradition also revive. Continuously in the 18th and 19th centuries CE, as part of the annual Saturnalia abuse of the carnival in Rome, rabbis of the ghetto were forced to march through the city streets wearing foolish guise, jeered upon and pelted by a variety of missiles from the crowd. A petition of the Jewish community of Rome sent in 1836 to Pope Gregory XVI to stop the annual anti-semitic Saturnalia abuse got a negation: “It is not opportune to make any innovation.”

What city's carnival was the most famous for a long time?

A:
Venice
