Problem: Like aluminium, copper is 100% recyclable without any loss of quality, regardless of whether it is in a raw state or contained in a manufactured product. In volume, copper is the third most recycled metal after iron and aluminium. It is estimated that 80% of the copper ever mined is still in use today. According to the International Resource Panel's Metal Stocks in Society report, the global per capita stock of copper in use in society is 3555 kg. Much of this is in more-developed countries (140300 kg per capita) rather than less-developed countries (3040 kg per capita).
What percentage of copper that has been mined is still being used today?
The answer is the following: 80%

The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. More than 133 billion litres (35 billion gallons) are sold per yearproducing total global revenues of $294.5 billion (147.7 billion) in 2006. The history of breweries has been one of absorbing smaller breweries in order to ensure economy of scale. In 2002 South African Breweries bought the North American Miller Brewing Company to found SABMiller, becoming the second largest brewery, after North American Anheuser-Bush. In 2004 the Belgian Interbrew was the third largest brewery by volume and the Brazilian AmBev was the fifth largest. They merged into InBev, becoming the largest brewery. In 2007, SABMiller surpassed InBev and Anheuser-Bush when it acquired Royal Grolsch, brewer of Dutch premium beer brand Grolsch in 2007. In 2008, InBev (the second-largest) bought Anheuser-Busch (the third largest), the new Anheuser-Busch InBev company became again the largest brewer in the world. As of 2015[update] AB InBev is the largest brewery, with SABMiller second, and Heineken International third.

Input: Marshall Islands
Most of the residents are Marshallese, who are of Micronesian origin and migrated from Asia several thousand years ago. A minority of Marshallese have some recent Asian ancestry, mainly Japanese. About one-half of the nation's population lives on Majuro, the capital, and Ebeye, a densely populated island. The outer islands are sparsely populated due to lack of employment opportunities and economic development. Life on the outer atolls is generally traditional.

From when did the Marshallese migrate from the Asian continent?
Output: several thousand years ago

Input: Article: Standing out in Clarke's (and Newton's) response to Leibniz's arguments is the bucket argument: Water in a bucket, hung from a rope and set to spin, will start with a flat surface. As the water begins to spin in the bucket, the surface of the water will become concave. If the bucket is stopped, the water will continue to spin, and while the spin continues, the surface will remain concave. The concave surface is apparently not the result of the interaction of the bucket and the water, since the surface is flat when the bucket first starts to spin, it becomes concave as the water starts to spin, and it remains concave as the bucket stops.

Now answer this question: If the buck stops, the water will do what?

Output: continue to spin

Article: Dogs have lived and worked with humans in so many roles that they have earned the unique nickname, "man's best friend", a phrase used in other languages as well. They have been bred for herding livestock, hunting (e.g. pointers and hounds), rodent control, guarding, helping fishermen with nets, detection dogs, and pulling loads, in addition to their roles as companions.
