Context and question: During a panel discussion at Harvard University's reunion for African American alumni during the 2003–04 academic year, two prominent black professors at the institution—Lani Guinier and Henry Louis Gates—pointed 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.
What portion of black Harvard undergraduates came from families in which all four grandparents were born into the African American community?
Answer: a third
Context and question: Richmond's original street grid, laid out in 1737, included the area between what are now Broad, 17th, and 25th Streets and the James River. Modern Downtown Richmond is located slightly farther west, on the slopes of Shockoe Hill. Nearby neighborhoods include Shockoe Bottom, the historically significant and low-lying area between Shockoe Hill and Church Hill, and Monroe Ward, which contains the Jefferson Hotel. Richmond's East End includes neighborhoods like rapidly gentrifying Church Hill, home to St. John's Church, as well as poorer areas like Fulton, Union Hill, and Fairmont, and public housing projects like Mosby Court, Whitcomb Court, Fairfield Court, and Creighton Court closer to Interstate 64.
What neighborhood is located in between Church and Shockoe Hill?
Answer: Shockoe Bottom
Context and question: In March 2015, the winds and storm surge created by Cyclone Pam resulted in waves of 3 metres (9.8 ft) to 5 metres (16 ft) breaking over the reef of the outer islands caused damage to houses, crops and infrastructure. On Nui the sources of fresh water were destroyed or contaminated. The flooding in Nui and Nukufetau caused many families to shelter in evacuation centres or with other families. Nui suffered the most damage of the three central islands (Nui, Nukufetau and Vaitupu); with both Nui and Nukufetau suffering the loss of 90% of the crops. Of the three northern islands (Nanumanga, Niutao, Nanumea), Nanumanga suffered the most damage, with 60-100 houses flooded, with the waves also causing damage to the health facility. Vasafua islet, part of the Funafuti Conservation Area, was severely damaged by Cyclone Pam. The coconut palms were washed away, leaving the islet as a sand bar.
The loss of what caused the Vasafua islet to become  a sand bar due to Cyclone Pam?
Answer:
coconut palms
