Input: Read this: While the decision (with four dissents) ultimately upheld the state law allowing the funding of transportation of students to religious schools, the majority opinion (by Justice Hugo Black) and the dissenting opinions (by Justice Wiley Blount Rutledge and Justice Robert H. Jackson) each explicitly stated that the Constitution has erected a "wall between church and state" or a "separation of Church from State": their disagreement was limited to whether this case of state funding of transportation to religious schools breached that wall. Rutledge, on behalf of the four dissenting justices, took the position that the majority had indeed permitted a violation of the wall of separation in this case: "Neither so high nor so impregnable today as yesterday is the wall raised between church and state by Virginia's great statute of religious freedom and the First Amendment, now made applicable to all the states by the Fourteenth." Writing separately, Justice Jackson argued that "[T]here are no good grounds upon which to support the present legislation. In fact, the undertones of the opinion, advocating complete and uncompromising separation of Church from State, seem utterly discordant with its conclusion yielding support to their commingling in educational matters."
Question: What did the decision not uphold?

Output: unanswerable

Input: Read this: Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted in only the last 24 years. As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction). However, only a tiny fraction of these reserves is economically viable, given present-day prices and technologies. Various estimates of existing copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.
Question: How much copper is estimated to exsist on earth?

Output: 1014 tons

Input: Read this: 3 kV DC is used in Belgium, Italy, Spain, Poland, the northern Czech Republic, Slovakia, Slovenia, South Africa, Chile, and former Soviet Union countries (also using 25 kV 50 Hz AC). It was formerly used by the Milwaukee Road from Harlowton, Montana to Seattle-Tacoma, across the Continental Divide and including extensive branch and loop lines in Montana, and by the Delaware, Lackawanna & Western Railroad (now New Jersey Transit, converted to 25 kV AC) in the United States, and the Kolkata suburban railway (Bardhaman Main Line) in India, before it was converted to 25 kV 50 Hz AC.
Question: What was formally used by the Mississippi Road?

Output: unanswerable

Input: Read this: After World War II, eastern European countries such as the Soviet Union, Poland, Czechoslovakia, Hungary, Romania and Yugoslavia expelled the Germans from their territories. Many of those had inhabited these lands for centuries, developing a unique culture. Germans were also forced to leave the former eastern territories of Germany, which were annexed by Poland (Silesia, Pomerania, parts of Brandenburg and southern part of East Prussia) and the Soviet Union (northern part of East Prussia). Between 12 and 16,5 million ethnic Germans and German citizens were expelled westwards to allied-occupied Germany.
Question: Where were Germans that were inhabiting other lands expelled to?

Output:
allied-occupied Germany
