Input: Read this: Ethnohistory is the study of ethnographic cultures and indigenous customs by examining historical records. It is also the study of the history of various ethnic groups that may or may not exist today. Ethnohistory uses both historical and ethnographic data as its foundation. Its historical methods and materials go beyond the standard use of documents and manuscripts. Practitioners recognize the utility of such source material as maps, music, paintings, photography, folklore, oral tradition, site exploration, archaeological materials, museum collections, enduring customs, language, and place names.
Question: What does ethnohistory use both historical and ethnographic data as?

Output: its foundation

Input: Read this: Trade secret misappropriation is different from violations of other intellectual property laws, since by definition trade secrets are secret, while patents and registered copyrights and trademarks are publicly available. In the United States, trade secrets are protected under state law, and states have nearly universally adopted the Uniform Trade Secrets Act. The United States also has federal law in the form of the Economic Espionage Act of 1996 (18 U.S.C. 18311839), which makes the theft or misappropriation of a trade secret a federal crime. This law contains two provisions criminalizing two sorts of activity. The first, 18 U.S.C. 1831(a), criminalizes the theft of trade secrets to benefit foreign powers. The second, 18 U.S.C. 1832, criminalizes their theft for commercial or economic purposes. (The statutory penalties are different for the two offenses.) In Commonwealth common law jurisdictions, confidentiality and trade secrets are regarded as an equitable right rather than a property right but penalties for theft are roughly the same as the United States.[citation needed]
Question: What do most US states use the Economic Espionage Act to protect?

Output: unanswerable

Input: Read this: Although the majority of journeys involving central London are made by public transport, car travel is common in the suburbs. The inner ring road (around the city centre), the North and South Circular roads (in the suburbs), and the outer orbital motorway (the M25, outside the built-up area) encircle the city and are intersected by a number of busy radial routesbut very few motorways penetrate into inner London. A plan for a comprehensive network of motorways throughout the city (the Ringways Plan) was prepared in the 1960s but was mostly cancelled in the early 1970s. The M25 is the longest ring-road motorway in the world at 121.5 mi (195.5 km) long. The A1 and M1 connect London to Leeds, and Newcastle and Edinburgh.
Question: What failed plan to install a major network of roadways within the City of London were eventually scrapped in the 1970s?

Output:
the Ringways Plan
