PROBLEM: Passage: In the immediate aftermath of World War II, the leadership of the Soviet Union feared the United States would use its nuclear superiority to its advantage, as from 1945 to 1948 the U.S. was the only state possessing nuclear weapons. The USSR countered by rapidly developing their own nuclear weapons, surprising the US with their first test in 1949. In turn, the U.S. countered by developing the vastly more powerful thermonuclear weapon, testing their first hydrogen bomb in 1952 at Ivy Mike, but the USSR quickly countered by testing their own thermonuclear weapons, with a test in 1953 of a semi-thermonuclear weapon of the Sloika design, and in 1956, with the testing of Sakharov's Third Idea equivalent to the Castle Bravo device. Meanwhile, tensions between the two nations rose as 1956 saw the suppression of Hungary by the Soviets; the U.S. and European nations drew certain conclusions from that event, while in the U.S., a powerful social backlash was afoot, prompted by Senator Joseph McCarthy, the House Un-American Activities Committee, and Julius and Ethel Rosenberg, U.S. citizens executed in 1953 after conviction of espionage. This atmosphere was further inflamed by the 1957 launch of Sputnik, which led to fears of Communists attacking from outer space, as well as concerns that if the Soviets could launch a device into orbit, they could equally cause a device to re-enter the atmosphere and impact any part of the planet. John F. Kennedy capitalized on this situation by emphasizing the Bomber gap and the Missile gap, areas in which the Soviets were (inaccurately) perceived as leading the United States, while heated Soviet rhetoric added to political pressure. The 1960 U-2 incident, involving Francis Gary Powers, as well as the Berlin Crisis, along with the test of the Tsar Bomba, escalated tensions still further.
Link Information: The Berlin Crisis of 1961 () occurred between 4 June 9 November 1961 Question: Which event occured first, the U2 incident or the Berlin Crisis?

PROBLEM: Passage: Nicolo's son Piergiampaolo inherited Sora and Alvito, while another son, Piergiovanni, inherited Popoli. Piergiampaolo soon annexed his brother's Abruzzese lands and, after siding against the new king, Ferdinand I, in the revolt of 1460, captured the territories of Montecassino, Arce, and the fiefs of the Colonna in Abruzzo. He also took part in the sieges of Sulmona and L'Aquila, but was in turn besieged and defeated by Napoleone Orsini at Sora. As a result, he was forced to cede Sora, Arpino, Casalvieri, Isola del Liri, and Fontana Liri to the Papal States in 1463. His duchy was downgraded to a county, the title being assigned to Piergiovanni. At the same time, Alvito and Sora were given the right to mint cavalli (a type of coin). Piergiampaolo organized a second plot against Ferdinand, but was again defeated and had to abandon hopes in returning to Alvito. Exiled to France, he returned with the invading army of Charles VIII of France during the War of 149495. With his brother, Sigismondo II of Sora, he re-conquered most of his lands. He was able to resist the Neapolitans after the French retreat, but in 1496 Sora fell to Frederick I of Naples, followed in 1496 by Alvito, captured by general Gonzalo de Cordoba. This put an end to the Cantelmo rule.

PROBLEM: Passage: When Isabella first became queen, she was only three years old. The queen mother, Maria Christina of the Two Sicilies, served as regent. The first and foremost political division of the Isabeline era was between Carlists and Cristinos (or Isabelinos), the former being supporters of Infante Carlos, Count of Molina, a rival claimant to the throne and the latter being supporters of Maria Christina and Isabella. The former supported absolute monarchism and the traditionalism of the Antiguo Regimen ("Old Regime"); they were uniformly close to the Roman Catholic Church, and generally clericalist. The latter were generally supporters of constitutional monarchy (although some, including Maria Christina herself, were more inclined toward enlightened absolutism); they were liberals of one stripe or another, ranging from liberal conservatives and those whose liberalism was strictly economic to social liberals. In the 1830s, these two groups faced off in the First Carlist War, which the Cristinos won. The terms of surrendernotably the Convention of Vergaraleft an opportunity for relatively moderate Carlists to continue to play a role in the country's politics, and many did so over the ensuing decades.
