Input: Read this: The first legislation providing federal authority for regulating pesticides was enacted in 1910; however, decades later during the 1940s manufacturers began to produce large amounts of synthetic pesticides and their use became widespread. Some sources consider the 1940s and 1950s to have been the start of the "pesticide era." Although the U.S. Environmental Protection Agency was established in 1970 and amendments to the pesticide law in 1972, pesticide use has increased 50-fold since 1950 and 2.3 million tonnes (2.5 million short tons) of industrial pesticides are now[when?] used each year. Seventy-five percent of all pesticides in the world are used in developed countries, but use in developing countries is increasing. A study of USA pesticide use trends through 1997 was published in 2003 by the National Science Foundation's Center for Integrated Pest Management.
Question: When did America establish the Environmental Protection Agency?

Output: 1970

The United States Air Force has had numerous recruiting slogans including "No One Comes Close" and Uno Ab Alto ("One From On High"). For many years, the U.S. Air Force used "Aim High" as its recruiting slogan; more recently, they have used "Cross into the Blue", "We've been waiting for you" and "Do Something Amazing", "Above All", and the newest one, as of 7 October 2010, considered a call and response, "Aim high" followed with the response, "Fly-Fight-Win" Each wing, group, or squadron usually has its own slogan(s).

If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does the USAF slogan Uno Ab Alto mean? 
Ah, so.. "One From On High"


Question: Historians disagree on what the relationship was between the Ming court and Tibet and whether or not Ming China had sovereignty over Tibet. Van Praag writes that Chinese court historians viewed Tibet as an independent foreign tributary and had little interest in Tibet besides a lama-patron relationship. The historian Tsepon W. D. Shakabpa supports van Praag's position. However, Wang Jiawei and Nyima Gyaincain state that these assertions by van Praag and Shakabpa are "fallacies".
Try to answer this question if possible: Who did not agree with van Praag and Shakabpa?
Answer: Wang Jiawei and Nyima Gyaincain


Context and question: The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid. Without predation, herbivores began to over-graze many woody browse species, affecting the area's plant populations. In addition, wolves often kept animals from grazing in riparian areas, which protected beavers from having their food sources encroached upon. The removal of wolves had a direct effect on beaver populations, as their habitat became territory for grazing. Furthermore, predation keeps hydrological features such as creeks and streams in normal working order. Increased browsing on willows and conifers along Blacktail Creek due to a lack of predation caused channel incision because they helped slow the water down and hold the soil in place.
What changes happened when herbivores were eliminated in Yellowstone?
Answer:
