Input: Spanish language in the United States
As civil wars engulfed several Central American countries in the 1980s, hundreds of thousands of Salvadorans fled their country and came to the United States. Between 1980 and 1990, the Salvadoran immigrant population in the United States increased nearly fivefold from 94,000 to 465,000. The number of Salvadoran immigrants in the United States continued to grow in the 1990s and 2000s as a result of family reunification and new arrivals fleeing a series of natural disasters that hit El Salvador, including earthquakes and hurricanes. By 2008, there were about 1.1 million Salvadoran immigrants in the United States.

Are the Salvadorans a large population in the U.S.?
Output: the Salvadoran immigrant population in the United States increased nearly fivefold from 94,000 to 465,000.


Input: Article: The climate of the Cretaceous is less certain and more widely disputed. Higher levels of carbon dioxide in the atmosphere are thought to have caused the world temperature gradient from north to south to become almost flat: temperatures were about the same across the planet. Average temperatures were also higher than today by about 10°C. In fact, by the middle Cretaceous, equatorial ocean waters (perhaps as warm as 20 °C in the deep ocean) may have been too warm for sea life,[dubious – discuss][citation needed] and land areas near the equator may have been deserts despite their proximity to water. The circulation of oxygen to the deep ocean may also have been disrupted.[dubious – discuss] For this reason, large volumes of organic matter that was unable to decompose accumulated, eventually being deposited as "black shale".

Now answer this question: What did large amounts of deposited un-decomposed organic matter later become?

Output: black shale


Article: At the invitation of the United States government, the Organization for Security and Cooperation in Europe (OSCE) sent a team of observers to monitor the presidential elections in 2004. It was the first time the OSCE had sent observers to a U.S. presidential election, although they had been invited in the past. In September 2004 the OSCE issued a report on U.S. electoral processes and the election final report. The report reads: "The November 2, 2004 elections in the United States mostly met the OSCE commitments included in the 1990 Copenhagen Document. They were conducted in an environment that reflects a long-standing democratic tradition, including institutions governed by the rule of law, free and generally professional media, and a civil society intensively engaged in the election process. There was exceptional public interest in the two leading presidential candidates and the issues raised by their respective campaigns, as well as in the election process itself."

Question: Was this the only occasion the OSCE was invited to preside over a presidential election?
Ans: It was the first time the OSCE had sent observers to a U.S. presidential election, although they had been invited in the past.

The problem: Answer a question about this article:
Western Europe's largest Jewish community, and the third-largest Jewish community in the world, can be found in France, home to between 483,000 and 500,000 Jews, the majority of whom are immigrants or refugees from North African Arab countries such as Algeria, Morocco, and Tunisia (or their descendants). The United Kingdom has a Jewish community of 292,000. In Eastern Europe, there are anywhere from 350,000 to one million Jews living in the former Soviet Union, but exact figures are difficult to establish. In Germany, the 102,000 Jews registered with the Jewish community are a slowly declining population, despite the immigration of tens of thousands of Jews from the former Soviet Union since the fall of the Berlin Wall. Thousands of Israelis also live in Germany, either permanently or temporarily, for economic reasons.
How many Jews live in France?
****
The answer: between 483,000 and 500,000


The problem: Answer a question about this article:
The end of World War II set the stage for the East–West confrontation known as the Cold War. With the outbreak of the Korean War, concerns over the defense of Western Europe rose. Two corps, V and VII, were reactivated under Seventh United States Army in 1950 and American strength in Europe rose from one division to four. Hundreds of thousands of U.S. troops remained stationed in West Germany, with others in Belgium, the Netherlands and the United Kingdom, until the 1990s in anticipation of a possible Soviet attack.
What war occurred after the end of World War II?
****
The answer:
Cold War
