Sometimes people of mixed African-American and Native American descent report having had elder family members withholding pertinent genealogical information. Tracing the genealogy of African Americans can be a very difficult process, as censuses did not identify slaves by name before the American Civil War, meaning that most African Americans did not appear by name in those records. In addition, many white fathers who used slave women sexually, even those in long-term relationships like Thomas Jefferson's with Sally Hemings, did not acknowledge their mixed-race slave children in records, so paternity was lost.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who acknowledged their mixed-race slave children in records?
Ah, so.. unanswerable

Police development-aid to weak, failed or failing states is another form of transnational policing that has garnered attention. This form of transnational policing plays an increasingly important role in United Nations peacekeeping and this looks set to grow in the years ahead, especially as the international community seeks to develop the rule of law and reform security institutions in States recovering from conflict (Goldsmith and Sheptycki, 2007) With transnational police development-aid the imbalances of power between donors and recipients are stark and there are questions about the applicability and transportability of policing models between jurisdictions (Hills, 2009).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What kind of countries get no assistance with policing?
Ah, so.. unanswerable

The bandolim (Portuguese for "mandolin") was a favourite instrument within the Portuguese bourgeoisie of the 19th century, but its rapid spread took it to other places, joining other instruments. Today you can see mandolins as part of the traditional and folk culture of Portuguese singing groups and the majority of the mandolin scene in Portugal is in Madeira Island. Madeira has over 17 active mandolin Orchestras and Tunas. The mandolin virtuoso Fabio Machado is one of Portugal's most accomplished mandolin players. The Portuguese influence brought the mandolin to Brazil.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"):  Where is the Japanese mandolin scene located?
Ah, so..
unanswerable
