Problem: Southeast Asia:

The arts of Southeast Asia have affinity with the arts of other areas. Dance in much of Southeast Asia includes movement of the hands as well as the feet, to express the dance's emotion and meaning of the story that the ballerina is going to tell the audience. Most of Southeast Asia introduced dance into their court; in particular, Cambodian royal ballet represented them in the early 7th century before the Khmer Empire, which was highly influenced by Indian Hinduism. Apsara Dance, famous for strong hand and feet movement, is a great example of Hindu symbolic dance.

The Khmer Empire was influenced by what?

A: Indian Hinduism


Problem: The name of the winning team is engraved on the silver band around the base as soon as the final has finished, in order to be ready in time for the presentation ceremony. This means the engraver has just five minutes to perform a task which would take twenty under normal conditions, although time is saved by engraving the year on during the match, and sketching the presumed winner. During the final, the trophy wears is decorated with ribbons in the colours of both finalists, with the loser's ribbons being removed at the end of the game. Traditionally, at Wembley finals, the presentation is made at the Royal Box, with players, led by the captain, mounting a staircase to a gangway in front of the box and returning by a second staircase on the other side of the box. At Cardiff the presentation was made on a podium on the pitch.
Where is the cup presentation never made?

From circa 1932 until 1977, General Electric polluted the Housatonic River with PCBs discharges from the General Electric plant at Pittsfield, Massachusetts. Aroclor 1254 and Aroclor 1260, made by Monsanto was the primary contaminant of the pollution. The highest concentrations of PCBs in the Housatonic River are found in Woods Pond in Lenox, Massachusetts, just south of Pittsfield, where they have been measured up to 110 mg/kg in the sediment. About 50% of all the PCBs currently in the river are estimated to be retained in the sediment behind Woods Pond dam. This is estimated to be about 11,000 pounds of PCBs. Former filled oxbows are also polluted. Waterfowl and fish who live in and around the river contain significant levels of PCBs and can present health risks if consumed.
How high have the levels of PCBs in the sediments behind Woods Pond dam been measured at?
A: 110 mg/kg


Context and question: Wang and Nyima state that after the official title "Education Minister" was granted to Tai Situ Changchub Gyaltsen (1302–1364) by the Yuan court, this title appeared frequently with his name in various Tibetan texts, while his Tibetan title "Degsi" (sic properly sde-srid or desi) is seldom mentioned. Wang and Nyima take this to mean that "even in the later period of the Yuan dynasty, the Yuan imperial court and the Phagmodrupa Dynasty maintained a Central-local government relation." The Tai Situpa is even supposed to have written in his will: "In the past I received loving care from the emperor in the east. If the emperor continues to care for us, please follow his edicts and the imperial envoy should be well received."
What dynasty kept a Central-local government relation with the Yuan imperial court?
Answer: Phagmodrupa Dynasty


Question: Outside of the Netherlands and Belgium, the dialect around the German town of Kleve (South Guelderish) both historically and genetically belongs to the Dutch language. In Northeastern France, the area around Calais was historically Dutch-speaking (West Flemish) of which an estimated 20,000 daily speakers. The cities of Dunkirk, Gravelines and Bourbourg only became predominantly French-speaking by the end of the 19th century. In the countryside, until World War I, many elementary schools continued to teach in Dutch, and the Catholic Church continued to preach and teach the catechism in Flemish in many parishes.
Is there an answer to this question: It took until the end of what century for people in French cities like Gravelines to finally switch over to French from Dutch?

The service's B-2A aircraft entered service in the 1990s, its B-1B aircraft in the 1980s and its current B-52H aircraft in the early 1960s. The B-52 Stratofortress airframe design is over 60 years old and the B-52H aircraft currently in the active inventory were all built between 1960 and 1962. The B-52H is scheduled to remain in service for another 30 years, which would keep the airframe in service for nearly 90 years, an unprecedented length of service for any aircraft. The B-21 is projected to replace the B-52 and parts of the B-1B force by the mid-2020s.
What aircraft in the USAF was introduced in the 1960s?
A:
B-52H
