TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: Seattle is one of the what of the country?, Context: Of the city's population over the age of 25, 53.8% (vs. a national average of 27.4%) hold a bachelor's degree or higher, and 91.9% (vs. 84.5% nationally) have a high school diploma or equivalent. A 2008 United States Census Bureau survey showed that Seattle had the highest percentage of college and university graduates of any major U.S. city. The city was listed as the most literate of the country's 69 largest cities in 2005 and 2006, the second most literate in 2007 and the most literate in 2008 in studies conducted by Central Connecticut State University.

SOLUTION: 69 largest cities

PROBLEM: The outside of a penny was made of?, Context: In 1982, the US Mint began minting pennies coated in copper but made primarily of zinc. With the new zinc pennies, there is the potential for zinc toxicosis, which can be fatal. One reported case of chronic ingestion of 425 pennies (over 1 kg of zinc) resulted in death due to gastrointestinal bacterial and fungal sepsis, whereas another patient, who ingested 12 grams of zinc, only showed lethargy and ataxia (gross lack of coordination of muscle movements). Several other cases have been reported of humans suffering zinc intoxication by the ingestion of zinc coins.

SOLUTION: copper

PROBLEM: What moved on keels?, Context: In the Sandgate area, to the east of the city and beside the river, resided the close-knit community of keelmen and their families. They were so called because they worked on the keels, boats that were used to transfer coal from the river banks to the waiting colliers, for export to London and elsewhere. In the 1630s about 7,000 out of 20,000 inhabitants of Newcastle died of plague, more than one-third of the population. Specifically within the year 1636, it is roughly estimated with evidence held by the Society of Antiquaries that 47% of the then population of Newcastle died from the epidemic; this may also have been the most devastating loss in any British City in this period.

SOLUTION:
coal
