Example Input: By 287 BC, the economic condition of the average plebeian had become poor. The problem appears to have centered around widespread indebtedness. The plebeians demanded relief, but the senators refused to address their situation. The result was the final plebeian secession. The plebeians seceded to the Janiculum hill. To end the secession, a dictator was appointed. The dictator passed a law (the Lex Hortensia), which ended the requirement that the patrician senators must agree before any bill could be considered by the Plebeian Council. This was not the first law to require that an act of the Plebeian Council have the full force of law. The Plebeian Council acquired this power during a modification to the original Valerian law in 449 BC. The significance of this law was in the fact that it robbed the patricians of their final weapon over the plebeians. The result was that control over the state fell, not onto the shoulders of voters, but to the new plebeian nobility.
Example Output: What was the economic status of your typical plebeian in 287 BC?

Example Input: During the years 1940-1955, the rate of decline in the U.S. death rate accelerated from 2% per year to 8% per year, then returned to the historical rate of 2% per year. The dramatic decline in the immediate post-war years has been attributed to the rapid development of new treatments and vaccines for infectious disease that occurred during these years. Vaccine development continued to accelerate, with the most notable achievement of the period being Jonas Salk's 1954 development of the polio vaccine under the funding of the non-profit National Foundation for Infantile Paralysis. The vaccine process was never patented, but was instead given to pharmaceutical companies to manufacture as a low-cost generic. In 1960 Maurice Hilleman of Merck Sharp & Dohme identified the SV40 virus, which was later shown to cause tumors in many mammalian species. It was later determined that SV40 was present as a contaminant in polio vaccine lots that had been administered to 90% of the children in the United States. The contamination appears to have originated both in the original cell stock and in monkey tissue used for production. In 2004 the United States Cancer Institute announced that it had concluded that SV40 is not associated with cancer in people.
Example Output: When was the Polio vaccine created?

Example Input: Although lacking historical connections to the Middle East, Japan was the country most dependent on Arab oil. 71% of its imported oil came from the Middle East in 1970. On November 7, 1973, the Saudi and Kuwaiti governments declared Japan a "nonfriendly" country to encourage it to change its noninvolvement policy. It received a 5% production cut in December, causing a panic. On November 22, Japan issued a statement "asserting that Israel should withdraw from all of the 1967 territories, advocating Palestinian self-determination, and threatening to reconsider its policy toward Israel if Israel refused to accept these preconditions". By December 25, Japan was considered an Arab-friendly state.
Example Output:
Which country is the most dependent on Arab oil?
