In the colonial years, while conditions were more fluid, white women, indentured servant or free, and African men, servant, slave or free, made unions. Because the women were free, their mixed-race children were born free; they and their descendants formed most of the families of free people of color during the colonial period in Virginia. The scholar Paul Heinegg found that eighty percent of the free people of color in North Carolina in censuses from 1790–1810 could be traced to families free in Virginia in colonial years.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What censuses did he study?
Ah, so.. from 1790–1810

The Basic Law of the Federal Republic of Germany, the federal constitution, stipulates that the structure of each Federal State's government must "conform to the principles of republican, democratic, and social government, based on the rule of law" (Article 28). Most of the states are governed by a cabinet led by a Ministerpräsident (Minister-President), together with a unicameral legislative body known as the Landtag (State Diet). The states are parliamentary republics and the relationship between their legislative and executive branches mirrors that of the federal system: the legislatures are popularly elected for four or five years (depending on the state), and the Minister-President is then chosen by a majority vote among the Landtag's members. The Minister-President appoints a cabinet to run the state's agencies and to carry out the executive duties of the state's government.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are most state legislatures called?
Ah, so.. Landtag

The National Library of Nepal is located in Patan. It is the largest library in the country with more than 70,000 books. English, Nepali, Sanskrit, Hindi, and Nepal Bhasa books are found here. The library is in possession of rare scholarly books in Sanskrit and English dating from the 17th century AD. Kathmandu also contains the Kaiser Library, located in the Kaiser Mahal on the ground floor of the Ministry of Education building. This collection of around 45,000 books is derived from a personal collection of Kaiser Shamsher Jang Bahadur Rana. It covers a wide range of subjects including history, law, art, religion, and philosophy, as well as a Sanskrit manual of Tantra, which is believed to be over 1,000 years old. The 2015 earthquake caused severe damage to the Ministry of Education building, and the contents of the Kaiser Library have been temporarily relocated.

Ah, so..
