Problem: Russian language:

The Russian alphabet has many systems of character encoding. KOI8-R was designed by the Soviet government and was intended to serve as the standard encoding. This encoding was and still is widely used in UNIX-like operating systems. Nevertheless, the spread of MS-DOS and OS/2 (IBM866), traditional Macintosh (ISO/IEC 8859-5) and Microsoft Windows (CP1251) created chaos and ended by establishing different encodings as de facto standards, with Windows-1251 becoming a de facto standard in Russian Internet and e-mail communication during the period of roughly 19952005.

How did the chaos created by the K018-R end?

Problem: Salyut 1's orbit was increased to prevent premature reentry, but further piloted flights were delayed while the Soyuz was redesigned to fix the new safety problem. The station re-entered the Earth's atmosphere on October 11, after 175 days in orbit. The USSR attempted to launch a second Salyut-class station designated Durable Orbital Station-2 (DOS-2) on July 29, 1972, but a rocket failure caused it to fail to achieve orbit. After the DOS-2 failure, the USSR attempted to launch four more Salyut-class stations through 1975, with another failure due to an explosion of the final rocket stage, which punctured the station with shrapnel so that it wouldn't hold pressure. While all of the Salyuts were presented to the public as non-military scientific laboratories, some of them were actually covers for the military Almaz reconnaissance stations.
How long did the station, Salyut 1, stay in orbit?

Answer: 175 days

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
As a result of the Libyan Civil War, the United Nations enacted United Nations Security Council Resolution 1973, which imposed a no-fly zone over Libya, and the protection of civilians from the forces of Muammar Gaddafi. The United States, along with Britain, France and several other nations, committed a coalition force against Gaddafi's forces. On 19 March, the first U.S. action was taken when 114 Tomahawk missiles launched by US and UK warships destroyed shoreline air defenses of the Gaddafi regime. The U.S. continued to play a major role in Operation Unified Protector, the NATO-directed mission that eventually incorporated all of the military coalition's actions in the theater. Throughout the conflict however, the U.S. maintained it was playing a supporting role only and was following the UN mandate to protect civilians, while the real conflict was between Gaddafi's loyalists and Libyan rebels fighting to depose him. During the conflict, American drones were also deployed.
What was the name of the military action against Libya?
A: Operation Unified Protector

Context and question: However, the battle was one-sided almost from the beginning. The reasons for this are the subject of continuing study by military strategists and academics. There is general agreement that US technological superiority was a crucial factor but the speed and scale of the Iraqi collapse has also been attributed to poor strategic and tactical leadership and low morale among Iraqi troops, which resulted from a history of incompetent leadership. After devastating initial strikes against Iraqi air defenses and command and control facilities on 17 January 1991, coalition forces achieved total air superiority almost immediately. The Iraqi air force was destroyed within a few days, with some planes fleeing to Iran, where they were interned for the duration of the conflict. The overwhelming technological advantages of the US, such as stealth aircraft and infrared sights, quickly turned the air war into a "turkey shoot". The heat signature of any tank which started its engine made an easy target. Air defense radars were quickly destroyed by radar-seeking missiles fired from wild weasel aircraft. Grainy video clips, shot from the nose cameras of missiles as they aimed at impossibly small targets, were a staple of US news coverage and revealed to the world a new kind of war, compared by some to a video game. Over 6 weeks of relentless pounding by planes and helicopters, the Iraqi army was almost completely beaten but did not retreat, under orders from Iraqi President Saddam Hussein, and by the time the ground forces invaded on 24 February, many Iraqi troops quickly surrendered to forces much smaller than their own; in one instance, Iraqi forces attempted to surrender to a television camera crew that was advancing with coalition forces.
US airstrikes on Iranian air defenses and command and control facilities began when?
Answer: unanswerable

Question: Eleven days after the Soviet invasion of the Polish Kresy, the secret protocol of the MolotovRibbentrop Pact was modified by the GermanSoviet Treaty of Friendship, Cooperation and Demarcation,) allotting Germany a larger part of Poland and transferring Lithuania's territory (with the exception of left bank of river Scheschupe, the "Lithuanian Strip") from the envisioned German sphere to the Soviets. On 28 September 1939, the Soviet Union and German Reich issued a joint declaration in which they declared:
Is there an answer to this question: How long after the annexation of Kresy was the amendment made?

Answer: Eleven days

Half the deported perished, and the other half were not allowed to return until the early 1960s (years after Stalin's death).[citation needed] The activities of Soviet forces in 194041 and after reoccupation sparked a guerrilla war against Soviet authorities in Estonia by the Forest Brothers, who consisted mostly of Estonian veterans of the German and Finnish armies and some civilians. This conflict continued into the early 1950s. Material damage caused by the world war and the following Soviet era significantly slowed Estonia's economic growth, resulting in a wide wealth gap in comparison with neighbouring Finland and Sweden.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What percentage of Estonians died after deporation?
Ah, so..
Half the deported perished
