Q: Discussions of strategy in the mid Ming dynasty focused primarily on recovery of the Ordos region, which the Mongols used as a rallying base to stage raids into Ming China. Norbu states that the Ming dynasty, preoccupied with the Mongol threat to the north, could not spare additional armed forces to enforce or back up their claim of sovereignty over Tibet; instead, they relied on "Confucian instruments of tribute relations" of heaping unlimited number of titles and gifts on Tibetan lamas through acts of diplomacy. Sperling states that the delicate relationship between the Ming and Tibet was "the last time a united China had to deal with an independent Tibet," that there was a potential for armed conflict at their borders, and that the ultimate goal of Ming foreign policy with Tibet was not subjugation but "avoidance of any kind of Tibetan threat." P. Christiaan Klieger argues that the Ming court's patronage of high Tibetan lamas "was designed to help stabilize border regions and protect trade routes."

A: What did the mid Ming dynasty discussion focus mainly on?

Q: The diversion of heavier bombers to the Balkans meant that the crews and units left behind were asked to fly two or three sorties per night. Bombers were noisy, cold, and vibrated badly. Added to the tension of the mission which exhausted and drained crews, tiredness caught up with and killed many. In one incident on 28/29 April, Peter Stahl of KG 30 was flying on his 50th mission. He fell asleep at the controls of his Ju 88 and woke up to discover the entire crew asleep. He roused them, ensured they took oxygen and Dextro-Energen tablets, then completed the mission.

A: How many sorties a night were crews asked to fly?

Q: La Diablada Carnival takes place in Oruro in central Bolivia. It is celebrated in honor of the miners' patron saint, Virgen de Socavon (the Virgin of the Tunnels).

It was declared the 2001 "Masterpieces of Oral Heritage and Intangible Heritage of Humanity" for UNESCO. Throughout the country celebrations are held involving traditional rhythms and water parties. In Santa Cruz de la Sierra, on the east side of the country, tropical weather allows a Brazilian-type Carnival, with Comparsas dancing traditional songs in matching uniforms.
