Question: Certain technological inventions of the period – whether of Arab or Chinese origin, or unique European innovations – were to have great influence on political and social developments, in particular gunpowder, the printing press and the compass. The introduction of gunpowder to the field of battle affected not only military organisation, but helped advance the nation state. Gutenberg's movable type printing press made possible not only the Reformation, but also a dissemination of knowledge that would lead to a gradually more egalitarian society. The compass, along with other innovations such as the cross-staff, the mariner's astrolabe, and advances in shipbuilding, enabled the navigation of the World Oceans, and the early phases of colonialism. Other inventions had a greater impact on everyday life, such as eyeglasses and the weight-driven clock.
Is there an answer to this question: What religious movement was spurred by the invention of the printing press?

Answer: the Reformation


Question: One problem with these assignments is admixture. Many people have a highly varied ancestry. For example, in the United States, colonial and early federal history were periods of numerous interracial relationships, both outside and inside slavery. This has resulted in a majority of people who identify as African American having some European ancestors. Similarly, many people who identify as white have some African ancestors. In a survey in a northeastern U.S. university of college students who identified as "white", about 30% were estimated to have up to 10% African ancestry.
Is there an answer to this question: When were periods of numerous interracial relationships in the U.S.?

Answer:
colonial and early federal history
