Of numerous relationships between male slaveholders, overseers, or master's sons and women slaves, the most notable is likely that of President Thomas Jefferson with his slave Sally Hemings. As noted in the 2012 collaborative Smithsonian-Monticello exhibit, Slavery at Monticello: The Paradox of Liberty, Jefferson, then a widower, took Hemings as his concubine for nearly 40 years. They had six children of record; four Hemings children survived into adulthood, and he freed them all, among the very few slaves he freed. Two were allowed to "escape" to the North in 1822, and two were granted freedom by his will upon his death in 1826. Seven-eighths white by ancestry, all four of his Hemings children moved to northern states as adults; three of the four entered the white community, and all their descendants identified as white. Of the descendants of Madison Hemings, who continued to identify as black, some in future generations eventually identified as white and "married out", while others continued to identify as African American. It was socially advantageous for the Hemings children to identify as white, in keeping with their appearance and the majority proportion of their ancestry. Although born into slavery, the Hemings children were legally white under Virginia law of the time.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How much of the children of Jefferson and Hemmings were white?
Ah, so.. Seven-eighths

Hunting in the United States is not associated with any particular class or culture; a 2006 poll showed seventy-eight percent of Americans supported legal hunting, although relatively few Americans actually hunt. At the beginning of the 21st century, just six percent of Americans hunted. Southerners in states along the eastern seaboard hunted at a rate of five percent, slightly below the national average, and while hunting was more common in other parts of the South at nine percent, these rates did not surpass those of the Plains states, where twelve percent of Midwesterners hunted. Hunting in other areas of the country fell below the national average. Overall, in the 19962006 period, the number of hunters over the age of sixteen declined by ten percent, a drop attributable to a number of factors including habitat loss and changes in recreation habits.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What percentage of states in the midwest had habitat loss on farms?
Ah, so.. unanswerable

Boston's colleges and universities have a significant effect on the regional economy. Boston attracts more than 350,000 college students from around the world, who contribute more than $4.8 billion annually to the city's economy. The area's schools are major employers and attract industries to the city and surrounding region. The city is home to a number of technology companies and is a hub for biotechnology, with the Milken Institute rating Boston as the top life sciences cluster in the country. Boston receives the highest absolute amount of annual funding from the National Institutes of Health of all cities in the United States.
