Q: Passage: Some scholars note that Tibetan leaders during the Ming frequently engaged in civil war and conducted their own foreign diplomacy with neighboring states such as Nepal. Some scholars underscore the commercial aspect of the Ming-Tibetan relationship, noting the Ming dynasty's shortage of horses for warfare and thus the importance of the horse trade with Tibet. Others argue that the significant religious nature of the relationship of the Ming court with Tibetan lamas is underrepresented in modern scholarship. In hopes of reviving the unique relationship of the earlier Mongol leader Kublai Khan (r. 1260–1294) and his spiritual superior Drogön Chögyal Phagpa (1235–1280) of the Sakya school of Tibetan Buddhism, the Yongle Emperor (r. 1402–1424) made a concerted effort to build a secular and religious alliance with Deshin Shekpa (1384–1415), the Karmapa of the Karma Kagyu school. However, the Yongle Emperor's attempts were unsuccessful. Question: Deshin Shekpa was the head of what school?

A: the Karma Kagyu school

Q: Passage: The strategy behind the formation of the Warsaw Pact was driven by the desire of the Soviet Union to dominate Central and Eastern Europe. This policy was driven by ideological and geostrategic reasons. Ideologically, the Soviet Union arrogated the right to define socialism and communism and act as the leader of the global socialist movement. A corollary to this idea was the necessity of intervention if a country appeared to be violating core socialist ideas and Communist Party functions, which was explicitly stated in the Brezhnev Doctrine. Geostrategic principles also drove the Soviet Union to prevent invasion of its territory by Western European powers. Question: The Soviet Union feared invasion from which potential enemy?

A: Western Europe

Q: Passage: Prior to its UK release, Spectre mostly received positive reviews. Mark Kermode, writing in The Guardian, gave the film four out of five stars, observing that the film did not live up to the standard set by Skyfall, but was able to tap into audience expectations. Writing in the same publication, Peter Bradshaw gave the film a full five stars, calling it "inventive, intelligent and complex", and singling out Craig's performance as the film's highlight. In another five star review, The Daily Telegraph's Robbie Collin described Spectre as "a swaggering show of confidence'", lauding it as "a feat of pure cinematic necromancy." In an otherwise positive, but overall less enthusiastic review, IGN's Chris Tilly considered Spectre "solid if unspectacular", and gave the film a 7.2 score (out of a possible 10), saying that "the film falls frustratingly short of greatness." Question: How many stars did Mark Kermode of the Guardian aware Spectre prior to its release?

A:
four out of five
