Input: Russian language
In the 20th century, Russian was mandatorily taught in the schools of the members of the old Warsaw Pact and in other countries that used to be satellites of the USSR. In particular, these countries include Poland, Bulgaria, the Czech Republic, Slovakia, Hungary, Albania, former East Germany and Cuba. However, younger generations are usually not fluent in it, because Russian is no longer mandatory in the school system. According to the Eurobarometer 2005 survey, though, fluency in Russian remains fairly high (2040%) in some countries, in particular those where the people speak a Slavic language and thereby have an edge in learning Russian (namely, Poland, Czech Republic, Slovakia, and Bulgaria).

What pact contained many Russian-speaking countries?
Output: Warsaw Pact

Input: 2008 Sichuan earthquake
The central government estimates that over 7,000 inadequately engineered schoolrooms collapsed in the earthquake. Chinese citizens have since invented a catch phrase: "tofu-dregs schoolhouses" (Chinese: ), to mock both the quality and the quantity of these inferior constructions that killed so many school children. Due to the one-child policy, many families lost their only child when schools in the region collapsed during the earthquake. Consequently, Sichuan provincial and local officials have lifted the restriction for families whose only child was either killed or severely injured in the disaster. So-called "illegal children" under 18 years of age may be registered as legal replacements for their dead siblings; if the dead child was illegal, no further outstanding fines would apply. Reimbursement would not, however, be offered for fines that were already levied.

What catch-phrase was invented as a result of collapsed schools?
Output: tofu-dregs schoolhouses

Input: Dwight D. Eisenhower
In the years that followed, Eisenhower increased the number of U.S. military advisors in South Vietnam to 900 men. This was due to North Vietnam's support of "uprisings" in the south and concern the nation would fall. In May 1957 Diem, then President of South Vietnam, made a state visit to the United States for ten days. President Eisenhower pledged his continued support, and a parade was held in Diem's honor in New York City. Although Diem was publicly praised, in private Secretary of State John Foster Dulles conceded that Diem had been selected because there were no better alternatives.

Where was a parade held for the President of South Vietnam?
Output: New York City

Input: Gene
The nucleotide sequence of a gene's DNA specifies the amino acid sequence of a protein through the genetic code. Sets of three nucleotides, known as codons, each correspond to a specific amino acid.:6 Additionally, a "start codon", and three "stop codons" indicate the beginning and end of the protein coding region. There are 64 possible codons (four possible nucleotides at each of three positions, hence 43 possible codons) and only 20 standard amino acids; hence the code is redundant and multiple codons can specify the same amino acid. The correspondence between codons and amino acids is nearly universal among all known living organisms.

What indicates the beginning and end of the protein coding region?
Output:
a "start codon", and three "stop codons"
