Problem: Please answer a question about the following article about Copper:
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 35–55 kg. Much of this is in more-developed countries (140–300 kg per capita) rather than less-developed countries (30–40 kg per capita).
What percentage of copper that has been mined is still being used today?
A: 80%

Ashkenazi Jews have a noted history of achievement in Western societies in the fields of exact and social sciences, literature, finance, politics, media, and others. In those societies where they have been free to enter any profession, they have a record of high occupational achievement, entering professions and fields of commerce where higher education is required. Ashkenazi Jews have won a large number of the Nobel awards. While they make up about 2% of the U.S. population, 27% of United States Nobel prize winners in the 20th century, a quarter of Fields Medal winners, 25% of ACM Turing Award winners, half the world's chess champions, including 8% of the top 100 world chess players, and a quarter of Westinghouse Science Talent Search winners have Ashkenazi Jewish ancestry.

What percentage of Nobel award winners from the United States in the 20th century have been Ashkenazi Jews? 
Answer: 27%


Problem: Some stations that broadcast from smaller cities are private affiliates of the CBC, that is, stations which are owned by commercial broadcasters but predominantly incorporate CBC programming within their schedules. Such stations generally follow the CBC schedule, airing a minimum 40 hours per week of network programming. However, they may opt out of some CBC programming in order to air locally produced programs, syndicated series or programs purchased from other broadcasters, such as CTV Two, which do not have a broadcast outlet in the same market. In these cases, the CBC programming being displaced may be broadcast at a different time than the network, or may not be broadcast on the station at all. Most private affiliates generally opt out of CBC's afternoon schedule and Thursday night arts programming. Private affiliates carry the 10 p.m. broadcast of The National as a core part of the CBC schedule, but generally omitted the 11 p.m. repeat (which is no longer broadcast). Most private affiliates produce their own local newscasts for a duration of at least 35 minutes. Some of the private affiliates have begun adding CBC's overnight programming to their schedules since the network began broadcasting 24 hours a day.
Minimally, how many hours are devoted weekly to network programming in CBC's private affiliates?
The answer is the following: 40


During his brief majority reign, Murad IV (1612–1640) reasserted central authority and recaptured Iraq (1639) from the Safavids. The resulting Treaty of Zuhab of that same year decisively parted the Caucasus and adjacent regions between the two neighbouring empires as it had already been defined in the 1555 Peace of Amasya. The Sultanate of women (1648–1656) was a period in which the mothers of young sultans exercised power on behalf of their sons. The most prominent women of this period were Kösem Sultan and her daughter-in-law Turhan Hatice, whose political rivalry culminated in Kösem's murder in 1651. During the Köprülü Era (1656–1703), effective control of the Empire was exercised by a sequence of Grand Viziers from the Köprülü family. The Köprülü Vizierate saw renewed military success with authority restored in Transylvania, the conquest of Crete completed in 1669, and expansion into Polish southern Ukraine, with the strongholds of Khotyn and Kamianets-Podilskyi and the territory of Podolia ceding to Ottoman control in 1676.
Who recaptured Iraq in 1639?
Murad IV


Input: Anti-aircraft warfare
The British recognised the need for anti-aircraft capability a few weeks before World War I broke out; on 8 July 1914, the New York Times reported that the British government had decided to 'dot the coasts of the British Isles with a series of towers, each armed with two quick-firing guns of special design,' while 'a complete circle of towers' was to be built around 'naval installations' and 'at other especially vulnerable points.' By December 1914 the Royal Naval Volunteer Reserve (RNVR) was manning AA guns and searchlights assembled from various sources at some nine ports. The Royal Garrison Artillery (RGA) was given responsibility for AA defence in the field, using motorised two-gun sections. The first were formally formed in November 1914. Initially they used QF 1-pounder "pom-pom" (a 37 mm version of the Maxim Gun).

Where did the New York times report say towers with guns should go?
Output: the coasts of the British Isles
