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: Britain had been surprised by the sudden Prussian offensive but now began shipping supplies and ₤670,000 (equivalent to ₤89.9 million in 2015) to its new ally. A combined force of allied German states was organised by the British to protect Hanover from French invasion, under the command of the Duke of Cumberland. The British attempted to persuade the Dutch Republic to join the alliance, but the request was rejected, as the Dutch wished to remain fully neutral. Despite the huge disparity in numbers, the year had been successful for the Prussian-led forces on the continent, in contrast to disappointing British campaigns in North America.
Question: Who led the force to defend Hanover?

Output: under the command of the Duke of Cumberland


Input: Read this: In physics, degenerate matter refers to the ground state of a gas of fermions at a temperature near absolute zero. The Pauli exclusion principle requires that only two fermions can occupy a quantum state, one spin-up and the other spin-down. Hence, at zero temperature, the fermions fill up sufficient levels to accommodate all the available fermions—and in the case of many fermions, the maximum kinetic energy (called the Fermi energy) and the pressure of the gas becomes very large, and depends on the number of fermions rather than the temperature, unlike normal states of matter.
Question: What shrinks to accommodate fermions?

Output: unanswerable


Input: Read this: The Mildred Lane Kemper Art Museum, established in 1881, is one of the oldest teaching museums in the country. The collection includes works from 19th, 20th, and 21st century American and European artists, including George Caleb Bingham, Thomas Cole, Pablo Picasso, Max Ernst, Alexander Calder, Jackson Pollock, Rembrandt, Robert Rauschenberg, Barbara Kruger, and Christian Boltanski. Also in the complex is the 3,000 sq ft (300 m2) Newman Money Museum. In October 2006, the Kemper Art Museum moved from its previous location, Steinberg Hall, into a new facility designed by former faculty member Fumihiko Maki. Interestingly, the new Kemper Art Museum is located directly across from Steinberg Hall, which was Maki's very first commission in 1959.
Question: In what year was the Newman Money Museum established?

Output:
unanswerable
