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: What is the top level of schooling that is affected by the Gates Foundation's reforms?, Context: The K-12 and higher education reform programs of the Gates Foundation have been criticized by some education professionals, parents, and researchers because they have driven the conversation on education reform to such an extent that they may marginalize researchers who do not support Gates' predetermined policy preferences. Several Gates-backed policies such as small schools, charter schools, and increasing class sizes have been expensive and disruptive, but some studies indicate they have not improved educational outcomes and may have caused harm. Peer reviewed scientific studies at Stanford find that Charter Schools do not systematically improve student performance

SOLUTION: higher education

PROBLEM: Americans born in the country south of the United States are call what kind of Americans?, Context: According to a study by Dr. Paul Brest, Hispanics or "Latinos" include immigrants who are descendants of immigrants from the countries comprising Central and South America. In 1991, Mexican Americans, Puerto Ricans, and Cuban Americans made up 80% of the Latino population in the United States. Latinos are disadvantaged compared to White Americans and are more likely to live in poverty. They are the least well educated major ethnic group and suffered a 3% drop in high school completion rate while African Americans experienced a 12% increase between 1975-1990. In 1990, they constituted 9% of the population, but only received 3.1% of the bachelors's degrees awarded. At times when it is favorable to lawmakers, Latinos were considered "white" by the Jim Crow laws during the Reconstruction. In other cases, according to Paul Brest, Latinos have been classified as an inferior race and a threat to white purity. Latinos have encountered considerable discrimination in areas such as employment, housing, and education. Brest finds that stereotypes continue to be largely negative and many perceive Latinos as "lazy, unproductive, and on the dole." Furthermore, native-born Latino-Americans and recent immigrants are seen as identical since outsiders tend not to differentiate between Latino groups.

SOLUTION: Mexican

PROBLEM: Who attempted to fix the formula?, Context: Despite the dominance of the above formula, there are documented attempts of the financial industry, occurring before the crisis, to address the formula limitations, specifically the lack of dependence dynamics and the poor representation of extreme events. The volume "Credit Correlation: Life After Copulas", published in 2007 by World Scientific, summarizes a 2006 conference held by Merrill Lynch in London where several practitioners attempted to propose models rectifying some of the copula limitations. See also the article by Donnelly and Embrechts and the book by Brigo, Pallavicini and Torresetti, that reports relevant warnings and research on CDOs appeared in 2006.

SOLUTION:
several practitioners
