Problem: Question: "Which year did Rahmon receive a higher percentage of the vote in the election, 2006 or 1999?" Context: "The nation almost immediately fell into civil war that involved various factions fighting one another; these factions were often distinguished by clan loyalties. More than 500,000 residents fled during this time because of persecution, increased poverty and better economic opportunities in the West or in other former Soviet republics. Emomali Rahmon came to power in 1992, defeating former prime minister Abdumalik Abdullajanov in a November presidential election with 58% of the vote. The elections took place shortly after the end of the war, and Tajikistan was in a state of complete devastation. The estimated dead numbered over 100,000. Around 1.2 million people were refugees inside and outside of the country. In 1997, a ceasefire was reached between Rahmon and opposition parties under the guidance of Gerd D. Merrem, Special Representative to the Secretary General, a result widely praised as a successful United Nations peace keeping initiative. The ceasefire guaranteed 30% of ministerial positions would go to the opposition. Elections were held in 1999, though they were criticized by opposition parties and foreign observers as unfair and Rahmon was re-elected with 98% of the vote. Elections in 2006 were again won by Rahmon (with 79% of the vote) and he began his third term in office. Several opposition parties boycotted the 2006 election and the Organization for Security and Cooperation in Europe (OSCE) criticized it, although observers from the Commonwealth of Independent States claimed the elections were legal and transparent. Rahmon's administration came under further criticism from the OSCE in October 2010 for its censorship and repression of the media. The OSCE claimed that the Tajik Government censored Tajik and foreign websites and instituted tax inspections on independent printing houses that led to the cessation of printing activities for a number of independent newspapers." Answer:

A: 1999

Problem: Question: "Which were there more of, tons of high explosives or bombers?" Context: "In the north, substantial efforts were made against Newcastle-upon-Tyne and Sunderland, which were large ports on the English east coast. On 9 April 1941 Luftflotte 2 dropped 150 tons of high explosives and 50,000 incendiaries from 120 bombers in a five-hour attack. Sewer, rail, docklands, and electric installations were damaged. In Sunderland on 25 April, Luftflotte 2 sent 60 bombers which dropped 80 tons of high explosive and 9,000 incendiaries. Much damage was done. A further attack on the Clyde, this time at Greenock, took place on 6 and 7 May. However, as with the attacks in the south, the Germans failed to prevent maritime movements or cripple industry in the regions." Answer:

A: high explosives

Problem: Question: "What earned him his doctorate?" Context: "Since there were few posts in Hungary for mathematicians, and those were not well-paid, his father wanted von Neumann to follow him into industry and therefore invest his time in a more financially useful endeavor than mathematics. So it was decided that the best career path was to become a chemical engineer. This was not something that von Neumann had much knowledge of, so it was arranged for him to take a two-year non-degree course in chemistry at the University of Berlin, after which he sat the entrance exam to the prestigious ETH Zurich, which he passed in September 1923. At the same time, von Neumann also entered Pazmany Peter University in Budapest, as a Ph.D. candidate in mathematics. For his thesis, he chose to produce an axiomatization of Cantor's set theory. He passed his final examinations for his Ph.D. soon after graduating from ETH Zurich in 1926. He then went to the University of Gottingen on a grant from the Rockefeller Foundation to study mathematics under David Hilbert." Answer:

A: he chose to produce an axiomatization of Cantor's set theory

Problem: Question: "What benefit does the first mentioned system have over others?" Context: "A servo system differs from some stepper motor applications in that the position feedback is continuous while the motor is running; a stepper system relies on the motor not to "miss steps" for short term accuracy, although a stepper system may include a "home" switch or other element to provide long-term stability of control. For instance, when a typical dot matrix computer printer starts up, its controller makes the print head stepper motor drive to its left-hand limit, where a position sensor defines home position and stops stepping. As long as power is on, a bidirectional counter in the printer's microprocessor keeps track of print-head position." Answer:

A:
feedback is continuous while the motor is running
