Input: Article: Environmental damage in Thuringia has been reduced to a large extent after 1990. The condition of forests, rivers and air was improved by modernizing factories, houses (decline of coal heating) and cars, and contaminated areas such as the former Uranium surface mines around Ronneburg have been remediated. Today's environmental problems are the salination of the Werra river, caused by discharges of K+S salt mines around Unterbreizbach and overfertilisation in agriculture, damaging the soil and small rivers.

Now answer this question: What are today's big environmental problems?

Output: the salination of the Werra river

Input: Article: The east coast Appalachian system, originally forest covered, is relatively low and narrow and is bordered on the southeast and south by an important coastal plain. The Cordilleran system on the western side of the continent is lofty, broad and complicated having two branches, the Rocky Mountain System and the Pacific Mountain System. In between these mountain systems lie the Intermontaine Plateaus. Both the Columbia River and Colorado River rise far inland near the easternmost members of the Cordilleran system, and flow through plateaus and intermontaine basins to the ocean. Heavy forests cover the northwest coast, but elsewhere trees are found only on the higher ranges below the Alpine region. The intermontane valleys, plateaus and basins range from treeless to desert with the most arid region being in the southwest.

Now answer this question: Which two major rivers are located in the Cordilleran system?

Output: Columbia River and Colorado River

Input: Article: For less than a year between 186263, Peruvian ships, engaged in what became to be called the "blackbirding" trade, combed the smaller islands of Polynesia from Easter Island in the eastern Pacific to Tuvalu and the southern atolls of the Gilbert Islands (now Kiribati), seeking recruits to fill the extreme labour shortage in Peru. While some islanders were voluntary recruits the "blackbirders" were notorious for enticing islanders on to ships with tricks, such as pretending to be Christian missionaries, as well as kidnapping islanders at gun point. The Rev. A. W. Murray, the earliest European missionary in Tuvalu, reported that in 1863 about 170 people were taken from Funafuti and about 250 were taken from Nukulaelae, as there were fewer than 100 of the 300 recorded in 1861 as living on Nukulaelae.

Now answer this question: What was the name applied to the trade of dealing with labor hunters?

Output:
blackbirding
