Problem: Josip Broz Tito:

On 26 June 1950, the National Assembly supported a crucial bill written by Milovan Đilas and Tito about "self-management" (samoupravljanje): a type of cooperative independent socialist experiment that introduced profit sharing and workplace democracy in previously state-run enterprises which then became the direct social ownership of the employees. On 13 January 1953, they established that the law on self-management was the basis of the entire social order in Yugoslavia. Tito also succeeded Ivan Ribar as the President of Yugoslavia on 14 January 1953. After Stalin's death Tito rejected the USSR's invitation for a visit to discuss normalization of relations between two nations. Nikita Khrushchev and Nikolai Bulganin visited Tito in Belgrade in 1955 and apologized for wrongdoings by Stalin's administration. Tito visited the USSR in 1956, which signaled to the world that animosity between Yugoslavia and USSR was easing. However, the relationship between the USSR and Yugoslavia would reach another low in the late 1960s. Commenting on the crisis, Tito concluded that:

A: Milovan Đilas


Problem: The transition from independence to a relatively minor part of a larger union was not easily accepted. To quell uprisings Charles V was struggling to exert his power over the citizens of the city, who had struggled to gain a certain level of independence from the bishops and were not willing to cede this to their new lord. The heavily fortified castle Vredenburg was built to house a large garrison whose main task was to maintain control over the city. The castle would last less than 50 years before it was demolished in an uprising in the early stages of the Dutch Revolt.
Who tried to exert power over the bishop?

The gyromagnetic ratio γ is the constant of proportionality between the frequency ν of nuclear magnetic resonance (or electron paramagnetic resonance for electrons) and the applied magnetic field B: ν = γB. It is difficult to measure gyromagnetic ratios precisely because of the difficulties in precisely measuring B, but the value for protons in water at 7002298150000000000♠25 °C is known to better than one part per million. The protons are said to be "shielded" from the applied magnetic field by the electrons in the water molecule, the same effect that gives rise to chemical shift in NMR spectroscopy, and this is indicated by a prime on the symbol for the gyromagnetic ratio, γ′p. The gyromagnetic ratio is related to the shielded proton magnetic moment μ′p, the spin number I (I = 1⁄2 for protons) and the reduced Planck constant.
The gyromagnetic ratio is often difficult to determine due to difficulty accurately determining the value of what?
A: the applied magnetic field B


Context and question: In 1827, Hungarian physicist Ányos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings.
In what year did Jedlik begin experimenting with non-electromagnetism?
Answer: unanswerable


Question: On St. George's Night (Estonian: Jüriöö ülestõus) 23 April 1343, the indigenous Estonian population in the Duchy of Estonia, the Bishopric of Ösel-Wiek and the insular territories of the State of the Teutonic Order tried to rid themselves of the Danish and German rulers and landlords, who had conquered the country in the 13th century during the Livonian crusade, and to eradicate the non-indigenous Christian religion. After initial success the revolt was ended by the invasion of the Teutonic Order. In 1346 the Duchy of Estonia was sold for 19,000 Köln marks to the Teutonic Order by the King of Denmark. The shift of sovereignty from Denmark to the State of the Teutonic Order took place on 1 November 1346.
Is there an answer to this question: What date did sovereignty shift from the state of Denmark?

Answer: 1 November 1346

Douglas's business grew astronomically with the onset of World War II, employing as many as 44,000 people in 1943. To defend against air attack set designers from the Warner Brothers Studios prepared elaborate camouflage that disguised the factory and airfield. The RAND Corporation began as a project of the Douglas Company in 1945, and spun off into an independent think tank on May 14, 1948. RAND eventually acquired a 15-acre (61,000 m²) campus centrally located between the Civic Center and the pier entrance.
What company started as a project in 1945?
A:
RAND
