Problem: Question: "What country was Mstislav the Great from?" Context: "The last ruler to maintain united state was Mstislav the Great. After his death in 1132 the Kievan Rus' fell into recession and a rapid decline, and Mstislav's successor Yaropolk II of Kiev instead of focussing on the external threat of the Cumans was embroiled in conflicts with the growing power of the Novgorod Republic. In 1169, as the Kievan Rus' state was full of internal conflict, Andrei Bogolyubsky of Vladimir sacked the city of Kiev. The sack of the city fundamentally changed the perception of Kiev and was evidence of the fragmentation of the Kievan Rus'. By the end of the 12th century, the Kievan state became even further fragmented and had been divided into roughly twelve different principalities." Answer:

A: Kiev

Problem: Question: "What is found near the edge of the water as opposed to the reefs: sea cucumbers, eels, blue tangs, or anemones?" Context: "The marine life found here consists of anemones, urchins, sea cucumbers, and eels, which all live on the reefs along with turtles, conch and many varieties of marine fishes. The marine aquafauna is rich in conch, which has pearly-pink shells. Its meat is a favourite food supplement item and their shells are a collectors item. Other species of fish which are recorded close to the shore line in shallow waters are: sergeant majors, the blue chromis, brown chromis, surgeon fish; blue tangs and trumpet fish. On the shore are ghost crabs, which always live on the beach in small burrowed tunnels made in sand, and the hermit crabs, which live in land but lay eggs in water and which also eat garbage and sewerage. They spend some months in the sea during and after the hatching season." Answer:

A: blue tangs

Problem: Question: "What change was brought about?" Context: "Several MLB teams used to play regular exhibition games during the year against nearby teams in the other major league, but regular-season interleague play has made such games unnecessary. The two Canadian MLB teams, the Toronto Blue Jays of the American League and the Montreal Expos of the National League, met annually to play the Pearson Cup exhibition game; this tradition ended when the Expos moved to Washington DC for the 2005 season. Similarly, the New York Yankees played in the Mayor's Trophy Game against various local rivals from 1946 to 1983." Answer:

A: this tradition ended when the Expos moved to Washington DC for the 2005 season

Problem: Question: "Why was there a problem between the four sub-fields?" Context: "Sociocultural anthropology has been heavily influenced by structuralist and postmodern theories, as well as a shift toward the analysis of modern societies. During the 1970s and 1990s, there was an epistemological shift away from the positivist traditions that had largely informed the discipline.[page needed] During this shift, enduring questions about the nature and production of knowledge came to occupy a central place in cultural and social anthropology. In contrast, archaeology and biological anthropology remained largely positivist. Due to this difference in epistemology, the four sub-fields of anthropology have lacked cohesion over the last several decades." Answer:

A:
epistemological shift away from the positivist traditions
