[Q]: Extract the answer to the question from the following context. Question: Who is Henry Louis Gates? Context: During a panel discussion at Harvard University's reunion for African American alumni during the 200304 academic year, two prominent black professors at the institutionLani Guinier and Henry Louis Gatespointed out an unintended effect of affirmative action policies at Harvard. They stated that only about a third of black Harvard undergraduates were from families in which all four grandparents were born into the African American community. The majority of black students at Harvard were Caribbean and African immigrants or their children, with some others the mixed-race children of biracial couples. One Harvard student, born in the South Bronx to a black family whose ancestors have been in the United States for multiple generations, said that there were so few Harvard students from the historic African American community that they took to calling themselves "the descendants" (i.e., descendants of American slaves). The reasons for this underrepresentation of historic African Americans, and possible remedies, remain a subject of debate.

[Q]: Extract the answer to the question from the following context. Question: What type of TB patients are less likely to follow up? Context: Slow progress has led to frustration, expressed by executive director of the Global Fund to Fight AIDS, Tuberculosis and Malaria Mark Dybul: "we have the tools to end TB as a pandemic and public health threat on the planet, but we are not doing it." Several international organizations are pushing for more transparency in treatment, and more countries are implementing mandatory reporting of cases to the government, although adherence is often sketchy. Commercial treatment-providers may at times overprescribe second-line drugs as well as supplementary treatment, promoting demands for further regulations. The government of Brazil provides universal TB-care, which reduces this problem. Conversely, falling rates of TB-infection may not relate to the number of programs directed at reducing infection rates, but may be tied to increased level of education, income and health of the population. Costs of the disease, as calculated by the World Bank in 2009 may exceed 150 billion USD per year in "high burden" countries. Lack of progress eradicating the disease may also be due to lack of patient follow-up as among the 250M rural migrants in China.

The trio began playing together with the Cubs in 1902, and formed a double play combination that lasted through April 1912. The Cubs won the pennant four times between 1906 and 1910, often defeating the Giants en route to the World Series.
