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%

Problem: The Universal Film Manufacturing Company was incorporated in New York on April 30, 1912. Laemmle, who emerged as president in July 1912, was the primary figure in the partnership with Dintenfass, Baumann, Kessel, Powers, Swanson, Horsley, and Brulatour. Eventually all would be bought out by Laemmle. The new Universal studio was a vertically integrated company, with movie production, distribution and exhibition venues all linked in the same corporate entity, the central element of the Studio system era.
What was the fate of the other partners of the Universal Film Manufacturing Company?
The answer is the following: bought out by Laemmle

Problem: The original post-punk movement ended as the bands associated with the movement turned away from its aesthetics, often in favor of more commercial sounds. Many of these groups would continue recording as part of the new pop movement, with entryism becoming a popular concept. In the United States, driven by MTV and modern rock radio stations, a number of post-punk acts had an influence on or became part of the Second British Invasion of "New Music" there. Some shifted to a more commercial new wave sound (such as Gang of Four), while others were fixtures on American college radio and became early examples of alternative rock. Perhaps the most successful band to emerge from post-punk was U2, who combined elements of religious imagery together with political commentary into their often anthemic music.
How did bands associated with the original post-punk movement cause it to end?
The answer is the following: turned away from its aesthetics

Problem: The English word scientist is relatively recentfirst coined by William Whewell in the 19th century. Previously, people investigating nature called themselves natural philosophers. While empirical investigations of the natural world have been described since classical antiquity (for example, by Thales, Aristotle, and others), and scientific methods have been employed since the Middle Ages (for example, by Ibn al-Haytham, and Roger Bacon), the dawn of modern science is often traced back to the early modern period and in particular to the scientific revolution that took place in 16th- and 17th-century Europe. Scientific methods are considered to be so fundamental to modern science that some consider earlier inquiries into nature to be pre-scientific. Traditionally, historians of science have defined science sufficiently broadly to include those inquiries.
When was the beginning of modern science considered to be?
The answer is the following:
the scientific revolution
