Input: Read this: The first commercial LEDs were commonly used as replacements for incandescent and neon indicator lamps, and in seven-segment displays, first in expensive equipment such as laboratory and electronics test equipment, then later in such appliances as TVs, radios, telephones, calculators, as well as watches (see list of signal uses). Until 1968, visible and infrared LEDs were extremely costly, in the order of US$200 per unit, and so had little practical use. The Monsanto Company was the first organization to mass-produce visible LEDs, using gallium arsenide phosphide (GaAsP) in 1968 to produce red LEDs suitable for indicators. Hewlett Packard (HP) introduced LEDs in 1968, initially using GaAsP supplied by Monsanto. These red LEDs were bright enough only for use as indicators, as the light output was not enough to illuminate an area. Readouts in calculators were so small that plastic lenses were built over each digit to make them legible. Later, other colors became widely available and appeared in appliances and equipment. In the 1970s commercially successful LED devices at less than five cents each were produced by Fairchild Optoelectronics. These devices employed compound semiconductor chips fabricated with the planar process invented by Dr. Jean Hoerni at Fairchild Semiconductor. The combination of planar processing for chip fabrication and innovative packaging methods enabled the team at Fairchild led by optoelectronics pioneer Thomas Brandt to achieve the needed cost reductions. These methods continue to be used by LED producers.
Question: What modern company introduced LEDs in 1968?

Output: Hewlett Packard (HP)


QUES: By 1840, the Market Hall and Sheds, where fresh meat and produce were brought daily, became a hub of commercial activity. The slave trade also depended on the port of Charleston, where ships could be unloaded and the slaves bought and sold. The legal importation of African slaves had ended in 1808, although smuggling was significant. However, the domestic trade was booming. More than one million slaves were transported from the Upper South to the Deep South in the antebellum years, as cotton plantations were widely developed through what became known as the Black Belt. Many slaves were transported in the coastwise slave trade, with slave ships stopping at ports such as Charleston.

What year did the legal importation of slaves start?

QUES: The number of species invasions has been on the rise at least since the beginning of the 1900s. Species are increasingly being moved by humans (on purpose and accidentally). In some cases the invaders are causing drastic changes and damage to their new habitats (e.g.: zebra mussels and the emerald ash borer in the Great Lakes region and the lion fish along the North American Atlantic coast). Some evidence suggests that invasive species are competitive in their new habitats because they are subject to less pathogen disturbance. Others report confounding evidence that occasionally suggest that species-rich communities harbor many native and exotic species simultaneously while some say that diverse ecosystems are more resilient and resist invasive plants and animals. An important question is, "do invasive species cause extinctions?" Many studies cite effects of invasive species on natives, but not extinctions. Invasive species seem to increase local (i.e.: alpha diversity) diversity, which decreases turnover of diversity (i.e.: beta diversity). Overall gamma diversity may be lowered because species are going extinct because of other causes, but even some of the most insidious invaders (e.g.: Dutch elm disease, emerald ash borer, chestnut blight in North America) have not caused their host species to become extinct. Extirpation, population decline, and homogenization of regional biodiversity are much more common. Human activities have frequently been the cause of invasive species circumventing their barriers, by introducing them for food and other purposes. Human activities therefore allow species to migrate to new areas (and thus become invasive) occurred on time scales much shorter than historically have been required for a species to extend its range.
What invaders are causing changes in the Great Lakes region?

ANS: zebra mussels and the emerald ash borer


Some of the county's secondary schools have specialist school status. Some schools have sixth forms and others transfer their sixth formers to colleges. Several schools can trace their origins back many years, such as The Blue School in Wells and Richard Huish College in Taunton. Others have changed their names over the years such as Beechen Cliff School which was started in 1905 as the City of Bath Boys' School and changed to its present name in 1972 when the grammar school was amalgamated with a local secondary modern school, to form a comprehensive school. Many others were established and built since the Second World War. In 2006, 5,900 pupils in Somerset sat GCSE examinations, with 44.5% achieving 5 grades A-C including English and Maths (compared to 45.8% for England).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What 5 grades A-C percentage to they get at City of Bath Boys' School?
Ah, so.. unanswerable


Question: Copyright infringement is reproducing, distributing, displaying or performing a work, or to make derivative works, without permission from the copyright holder, which is typically a publisher or other business representing or assigned by the work's creator. It is often called "piracy". While copyright is created the instance a work is fixed, generally the copyright holder can only get money damages if the owner registers the copyright.[citation needed] Enforcement of copyright is generally the responsibility of the copyright holder. The ACTA trade agreement, signed in May 2011 by the United States, Japan, Switzerland, and the EU, and which has not entered into force, requires that its parties add criminal penalties, including incarceration and fines, for copyright and trademark infringement, and obligated the parties to active police for infringement. There are limitations and exceptions to copyright, allowing limited use of copyrighted works, which does not constitute infringement. Examples of such doctrines are the fair use and fair dealing doctrine.

QUES: Athanasius's episcopate began on 9 May 328 as the Alexandrian Council elected Athanasius to succeed the aged Alexander. That council also denounced various heresies and schisms, many of which continued to preoccupy his 45-year-long episcopate (c. 8 June 328 – 2 May 373). Patriarch Athanasius spent over 17 years in five exiles ordered by four different Roman Emperors, not counting approximately six more incidents in which Athanasius fled Alexandria to escape people seeking to take his life. This gave rise to the expression "Athanasius contra mundum" or "Athanasius against the world". However, during his first years as bishop, Athanasius visited the churches of his territory, which at that time included all of Egypt and Libya. He established contacts with the hermits and monks of the desert, including Pachomius, which proved very valuable to him over the years. Shortly thereafter, Athanasius became occupied with the theological disputes against Arians within the Byzantine Empire that would occupy much of his life.
 How many exiles did he evade?
