Problem: Queen Victoria:

Eleven days after Orsini's assassination attempt in France, Victoria's eldest daughter married Prince Frederick William of Prussia in London. They had been betrothed since September 1855, when Princess Victoria was 14 years old; the marriage was delayed by the Queen and Prince Albert until the bride was 17. The Queen and Albert hoped that their daughter and son-in-law would be a liberalising influence in the enlarging Prussian state. Victoria felt "sick at heart" to see her daughter leave England for Germany; "It really makes me shudder", she wrote to Princess Victoria in one of her frequent letters, "when I look round to all your sweet, happy, unconscious sisters, and think I must give them up too one by one." Almost exactly a year later, Princess Victoria gave birth to the Queen's first grandchild, Wilhelm, who would become the last German Kaiser.

How old was Princess Victoria when she agreed to divorce the Prince?

Problem: The High Middle Ages was a period of tremendous expansion of population. The estimated population of Europe grew from 35 to 80 million between 1000 and 1347, although the exact causes remain unclear: improved agricultural techniques, the decline of slaveholding, a more clement climate and the lack of invasion have all been suggested. As much as 90 per cent of the European population remained rural peasants. Many were no longer settled in isolated farms but had gathered into small communities, usually known as manors or villages. These peasants were often subject to noble overlords and owed them rents and other services, in a system known as manorialism. There remained a few free peasants throughout this period and beyond, with more of them in the regions of Southern Europe than in the north. The practice of assarting, or bringing new lands into production by offering incentives to the peasants who settled them, also contributed to the expansion of population.
During the High Middle Ages, what percentage of the European population consisted of rural peasants?

Answer: 90

Context and question: The Tito-Stalin split had large ramifications for countries outside the USSR and Yugoslavia. It has, for example, been given as one of the reasons for the Slansky trial in Czechoslovakia, in which 14 high-level Communist officials were purged, with 11 of them being executed. Stalin put pressure on Czechoslovakia to conduct purges in order to discourage the spread of the idea of a "national path to socialism," which Tito espoused.
Who espoused the "national path to socialism"?

QUES: Studies conducted on both animals and humans show major bidirectional relationships between the circadian system and abusive drugs. It is indicated that these abusive drugs affect the central circadian pacemaker. Individuals suffering from substance abuse display disrupted rhythms. These disrupted rhythms can increase the risk for substance abuse and relapse. It is possible that genetic and/or environmental disturbances to the normal sleep and wake cycle can increase the susceptibility to addiction.

What studies show a minor relationship between the circadian system and drug abuse?
