Problem: BBC Television:

Initially, the station's range was officially a 40 kilometres radius of the Alexandra Palace transmitterin practice, however, transmissions could be picked up a good deal further away, and on one occasion in 1938 were picked up by engineers at RCA in New York, who were experimenting with a British television set.

In what year were BBC broadcasts seen in the United States?

Problem: European maps continued to show this hypothesized land until Captain James Cook's ships, HMS Resolution and Adventure, crossed the Antarctic Circle on 17 January 1773, in December 1773 and again in January 1774. Cook came within about 120 km (75 mi) of the Antarctic coast before retreating in the face of field ice in January 1773. The first confirmed sighting of Antarctica can be narrowed down to the crews of ships captained by three individuals. According to various organizations (the National Science Foundation, NASA, the University of California, San Diego, and other sources), ships captained by three men sighted Antarctica or its ice shelf in 1820: von Bellingshausen (a captain in the Imperial Russian Navy), Edward Bransfield (a captain in the Royal Navy), and Nathaniel Palmer (a sealer out of Stonington, Connecticut). The expedition led by von Bellingshausen and Lazarev on the ships Vostok and Mirny reached a point within 32 km (20 mi) from Queen Maud's Land and recorded the sight of an ice shelf at 692128S 21450W / 69.35778S 2.24722W / -69.35778; -2.24722, which became known as the Fimbul ice shelf. This happened three days before Bransfield sighted land, and ten months before Palmer did so in November 1820. The first documented landing on Antarctica was by the American sealer John Davis, apparently at Hughes Bay, near Cape Charles, in West Antarctica on 7 February 1821, although some historians dispute this claim. The first recorded and confirmed landing was at Cape Adair in 1895.

Context and question: Anthropology is a global discipline where humanities, social, and natural sciences are forced to confront one another. Anthropology builds upon knowledge from natural sciences, including the discoveries about the origin and evolution of Homo sapiens, human physical traits, human behavior, the variations among different groups of humans, how the evolutionary past of Homo sapiens has influenced its social organization and culture, and from social sciences, including the organization of human social and cultural relations, institutions, social conflicts, etc. Early anthropology originated in Classical Greece and Persia and studied and tried to understand observable cultural diversity. As such, anthropology has been central in the development of several new (late 20th century) interdisciplinary fields such as cognitive science, global studies, and various ethnic studies.
What began in modern day Greece?

Question: Encouraged by these successes, Nintendo soon turned its attention to the North American market. Nintendo entered into negotiations with Atari to release the Famicom under Atari's name as the name Nintendo Advanced Video Gaming System. The deal was set to be finalized and signed at the Summer Consumer Electronics Show in June 1983. However, Atari discovered at that show that its competitor Coleco was illegally demonstrating its Coleco Adam computer with Nintendo's Donkey Kong game. This violation of Atari's exclusive license with Nintendo to publish the game for its own computer systems delayed the implementation of Nintendo's game console marketing contract with Atari. Atari's CEO Ray Kassar was fired the next month, so the deal went nowhere, and Nintendo decided to market its system on its own.g["]

Copper has been used since ancient times as a durable, corrosion resistant, and weatherproof architectural material. Roofs, flashings, rain gutters, downspouts, domes, spires, vaults, and doors have been made from copper for hundreds or thousands of years. Copper's architectural use has been expanded in modern times to include interior and exterior wall cladding, building expansion joints, radio frequency shielding, and antimicrobial indoor products, such as attractive handrails, bathroom fixtures, and counter tops. Some of copper's other important benefits as an architectural material include its low thermal movement, light weight, lightning protection, and its recyclability.
How long has copper been used in building construction?
A:
hundreds or thousands of years
