Input: Read this: By spring 1950, Stalin believed the strategic situation had changed. The Soviets had detonated their first nuclear bomb in September 1949; American soldiers had fully withdrawn from Korea; the Americans had not intervened to stop the communist victory in China, and Stalin calculated that the Americans would be even less willing to fight in Koreawhich had seemingly much less strategic significance. The Soviets had also cracked the codes used by the US to communicate with the US embassy in Moscow, and reading these dispatches convinced Stalin that Korea did not have the importance to the US that would warrant a nuclear confrontation. Stalin began a more aggressive strategy in Asia based on these developments, including promising economic and military aid to China through the SinoSoviet Friendship, Alliance, and Mutual Assistance Treaty.
Question: Who was convinced that the US did was no longer interested in Korea?

Output: Stalin

QUES: In the 1840s Nicholas I reduced 64,000 szlachta to commoner status. Despite this, 62.8% of Russia's nobles were szlachta in 1858 and still 46.1% in 1897. Serfdom was abolished in Russian Poland on February 19, 1864. It was deliberately enacted in a way that would ruin the szlachta. It was the only area where peasants paid the market price in redemption for the land (the average for the empire was 34% above the market price). All land taken from Polish peasants since 1846 was to be returned without redemption payments. The ex serfs could only sell land to other peasants, not szlachta. 90% of the ex serfs in the empire who actually gained land after 1861 were in the 8 western provinces. Along with Romania, Polish landless or domestic serfs were the only ones to be given land after serfdom was abolished. All this was to punish the szlachta's role in the uprisings of 1830 and 1863. By 1864 80% of szlachta were declasse, 1/4 petty nobles were worse off than the average serf, 48.9% of land in Russian Poland was in peasant hands, nobles still held 46%. In Second Polish Republic the privileges of the nobility were lawfully abolished by the March Constitution in 1921 and as such not granted by any future Polish law.

Who could the ex serfs sell their land to?
What is the answer?
ANS: only sell land to other peasants, not szlachta

QUES: Jim Foster, a promotions manager with the National Football League, conceived of indoor football while watching an indoor soccer match at Madison Square Garden in 1981. While at the game, he wrote his idea on a 9x12 envelope, with sketches of the field and notes on gameplay. He presented the idea to a few friends at the NFL offices, where he received praise and encouragement for his concept. After solidifying the rules and a business plan, and supplemented with sketches by a professional artist, Foster presented his idea to various television networks. He reached an agreement with NBC for a "test game".
In what year did Jim Foster conceive of the idea of arena football?

ANS: 1981

To prevent the risk of out-of-phase supplies mixing, sections of line fed from different feeder stations must be kept strictly isolated. This is achieved by Neutral Sections (also known as Phase Breaks), usually provided at feeder stations and midway between them although, typically, only half are in use at any time, the others being provided to allow a feeder station to be shut down and power provided from adjacent feeder stations. Neutral Sections usually consist of an earthed section of wire which is separated from the live wires on either side by insulating material, typically ceramic beads, designed so that the pantograph will smoothly run from one section to the other. The earthed section prevents an arc being drawn from one live section to the other, as the voltage difference may be higher than the normal system voltage if the live sections are on different phases and the protective circuit breakers may not be able to safely interrupt the considerable current that would flow. To prevent the risk of an arc being drawn across from one section of wire to earth, when passing through the neutral section, the train must be coasting and the circuit breakers must be open. In many cases, this is done manually by the drivers. To help them, a warning board is provided just before both the neutral section and an advance warning some distance before. A further board is then provided after the neutral section to tell drivers to re-close the circuit breaker, although drivers must not do this until the rear pantograph has passed this board. In the UK, a system known as Automatic Power Control (APC) automatically opens and closes the circuit breaker, this being achieved by using sets of permanent magnets alongside the track communicating with a detector on the train. The only action needed by the driver is to shut off power and coast and therefore warning boards are still provided at and on the approach to neutral sections.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What must not be coasting to prevent the risk of an arc being drawn?
Ah, so.. unanswerable

Question: As the playing of gramophone records causes gradual degradation of the recording, they are best preserved by transferring them onto other media and playing the records as rarely as possible. They need to be stored on edge, and do best under environmental conditions that most humans would find comfortable. The medium needs to be kept clean, but alcohol should only be used on PVC or optical media, not on 78s.[citation needed] The equipment for playback of certain formats (e.g., 16 and 78 rpm) is manufactured only in small quantities, leading to increased difficulty in finding equipment to play the recordings.
Try to answer this question if possible: Is gramophone equipment readily available?
Answer: manufactured only in small quantities

QUES: In January 2012, an armed conflict broke out in northern Mali, which Tuareg rebels took control of by April and declared the secession of a new state, Azawad. The conflict was complicated by a military coup that took place in March and later fighting between Tuareg and Islamist rebels. In response to Islamist territorial gains, the French military launched Operation Serval in January 2013. A month later, Malian and French forces recaptured most of the north. Presidential elections were held on 28 July 2013, with a second round run-off held on 11 August, and legislative elections were held on 24 November and 15 December 2013.
On July 28 2013 what type of elections were held?

ANS:
Presidential elections
