Cards A to D, all summaries in our words, written today. Card A (Cuba): In October 1962 Soviet missiles were secretly placed in Cuba. US planes photographed the sites on October 14, and on October 22 the United States ordered a naval quarantine. The missiles were removed under United Nations supervision, and the United States pledged not to invade Cuba. The United States also planned to remove its own missiles from Turkey, a part kept out of the public deal. The State Department's historians call it the closest the superpowers came to nuclear conflict. Card B (the wall): On August 13, 1961, a barbed-wire fence went up overnight between West and East Berlin on the orders of East German leader Walter Ulbricht. The wall divided families. It stayed until November 9, 1989. Card C (the Warsaw Pact): The Warsaw Treaty Organization was used to contain dissent in Hungary in 1956, Czechoslovakia in 1968 and Poland in 1981. East Germany left in September 1990, and the Pact was disbanded in 1991. Card D (the founding of the blocs): The Brussels Treaty was signed in March 1948. On June 24, 1948, the Berlin blockade began. The North Atlantic Treaty followed in 1949, agreeing that an attack on one is an attack on all. Greece and Turkey joined NATO in 1952, and West Germany joined in May 1955. The Warsaw Pact was established on May 14, 1955, as a counterbalance to NATO.
Card A says the Turkey missiles were kept out of the public deal. Ari asks what that does to a source that reports only the public deal.
- It leaves out part of the bargain, so it cannot show the full terms
- It is false, since a public deal and a secret one cannot both exist
- It is complete, since card A lists the pledge not to invade Cuba
- It is outdated, since the terms changed after October 28
Card B says the wall went up overnight on Ulbricht's orders. Bo asks what a reader could not learn from that summary.
- That the wall divided families, since the card says the wall did so
- That the wall stood for 28 years, since it fell in 1989
- That the wall began on August 13, 1961, since that date is hard to find
- Why East German leaders chose it, or what Berliners thought
Card C says the Warsaw Pact was used to contain dissent in 1956, 1968 and 1981. Esme asks what a reader should check about "contain dissent."
- That the Pact was formed in order to do this, since the card says it was used so
- That the members agreed to each action, since the Pact was a treaty among them
- That East Germany joined in 1990, since card C gives that year for it
- Whose wording it is, and what happened in each country behind the phrase
A student says NATO formed because of the Berlin blockade. What does card D show, Jun asks?
- The Brussels Treaty of March 1948 came before the blockade, so other reasons existed
- It holds in part, since the blockade was the sole danger NATO's members named
- It fails, since the blockade began after NATO was signed in 1949, so it could not be the cause
- It holds, since the North Atlantic Treaty came after the blockade and answered it
Card D says West Germany joined NATO in May 1955 and the Warsaw Pact formed on May 14. Kira asks what the order supports.
- It formed after Greece and Turkey joined NATO in 1952, so it answered them
- It formed just because of West Germany, since West Germany joined days before
- A reaction to West Germany is plausible, but card D says counterbalance to NATO
- It formed to attack West Germany, as the close timing of the two events shows
A student says the Cuban crisis ended because the US gave up nothing. What does card A show, Luz asks?
- The Soviets pledged not to invade Cuba, and the US removed missiles under UN watch
- The US pledged not to invade Cuba and planned to pull its Turkey missiles
- The US gave up nothing, since just the Soviet missiles left Cuba in public
- The US removed its missiles from Turkey before the quarantine of October 22
Milo compares Cuba in 1962 (card A) with the wall in 1961 (card B). Which statement is fair?
- Cuba ended in a deal; the wall was built by one side and stood 28 years
- Berlin ended in a pledge not to invade, as in Cuba, since both crises came in 1961 and 1962
- Both ended in a deal, since each crisis ended without a war between the superpowers
- The wall ended the Cuban crisis, since it went up before the quarantine
Pia compares NATO and the Warsaw Pact in card D. What does the card's wording show?
- They were alike in their wording, since both formed in reply to a threat
- Both were alliances; NATO pledged mutual defense, the Pact balanced NATO
- NATO formed after the Pact, so NATO was the counterbalance to the Pact
- The Pact pledged mutual defense and NATO was the counterbalance, as the card words them
The Warsaw Pact formed in 1955 and was disbanded in 1991. Ren asks what East Germany leaving in September 1990 shows.
- The Pact lasted 40 years, from 1949 to 1990, when East Germany left
- The Pact ended in September 1990, when East Germany left, after 35 years
- East Germany's exit caused the Pact's end
- The Pact lost a member in 1990, a year before it was disbanded after 36 years
The wall stood from August 1961 to November 1989. Tala asks what the span can show.
- Families were kept apart for the full 28 years, since the wall divided families
- A division lasting 30 years, since the wall went up in 1959 and fell in 1989
- A division lasting 28 years, though not how Berliners lived day to day
- The wall's fall caused the Cold War's end, since it came last of the events
