There are many styles of mandolin, but four are common, the Neapolitan or round-backed mandolin, the carved-top mandolin and the flat-backed mandolin. The round-back has a deep bottom, constructed of strips of wood, glued together into a bowl. The carved-top or arch-top mandolin has a much shallower, arched back, and an arched top—both carved out of wood. The flat-backed mandolin uses thin sheets of wood for the body, braced on the inside for strength in a similar manner to a guitar. Each style of instrument has its own sound quality and is associated with particular forms of music. Neapolitan mandolins feature prominently in European classical music and traditional music. Carved-top instruments are common in American folk music and bluegrass music. Flat-backed instruments are commonly used in Irish, British and Brazilian folk music. Some modern Brazilian instruments feature an extra fifth course tuned a fifth lower than the standard fourth course.

The development of writing enabled knowledge to be stored and communicated across generations with much greater fidelity. Combined with the development of agriculture, which allowed for a surplus of food, it became possible for early civilizations to develop, because more time and effort could be devoted to tasks (other than food production) than hunter-gatherers or early subsistence farmers had available. This surplus allowed a community to support individuals who did things other than work towards bare survival. These other tasks included systematic studies of nature, study of written information gathered and recorded by others, and often of adding to that body of information.

Question: Before agriculture advancements, what were farmers having to do?
Answer: work towards bare survival.

The novel exposes the loss of innocence so frequently that reviewer R. A. Dave claims that because every character has to face, or even suffer defeat, the book takes on elements of a classical tragedy. In exploring how each character deals with his or her own personal defeat, Lee builds a framework to judge whether the characters are heroes or fools. She guides the reader in such judgments, alternating between unabashed adoration and biting irony. Scout's experience with the Missionary Society is an ironic juxtaposition of women who mock her, gossip, and "reflect a smug, colonialist attitude toward other races" while giving the "appearance of gentility, piety, and morality". Conversely, when Atticus loses Tom's case, he is last to leave the courtroom, except for his children and the black spectators in the colored balcony, who rise silently as he walks underneath them, to honor his efforts.

Question: Reviewer R. A. Dave classified the novel how?
Answer: classical tragedy.

No satisfactory explanation can as yet be given for the exact mechanisms determining the formation of earlywood and latewood. Several factors may be involved. In conifers, at least, rate of growth alone does not determine the proportion of the two portions of the ring, for in some cases the wood of slow growth is very hard and heavy, while in others the opposite is true. The quality of the site where the tree grows undoubtedly affects the character of the wood formed, though it is not possible to formulate a rule governing it. In general, however, it may be said that where strength or ease of working is essential, woods of moderate to slow growth should be chosen.

Question: What species of tree can be said to growth ring proportions that aren't determined just by their rate of growth?
Answer: conifers.

Academics noted that with her videos, Madonna was subtly reversing the usual role of male as the dominant sex. This symbolism and imagery was probably the most prevalent in the music video for "Like a Prayer". The video included scenes of an African-American church choir, Madonna being attracted to a statue of a black saint, and singing in front of burning crosses. This mix of the sacred and the profane upset the Vatican and resulted in the Pepsi commercial withdrawal. In 2003, MTV named her "The Greatest Music Video Star Ever" and said that "Madonna's innovation, creativity and contribution to the music video art form is what won her the award."

This is not to say that Whitehead's thought was widely accepted or even well-understood. His philosophical work is generally considered to be among the most difficult to understand in all of the western canon. Even professional philosophers struggled to follow Whitehead's writings. One famous story illustrating the level of difficulty of Whitehead's philosophy centers around the delivery of Whitehead's Gifford lectures in 1927–28 – following Arthur Eddington's lectures of the year previous – which Whitehead would later publish as Process and Reality:

Popper had his own sophisticated views on evolution that go much beyond what the frequently-quoted passages say. In effect, Popper agreed with some of the points of both creationists and naturalists, but also disagreed with both views on crucial aspects. Popper understood the universe as a creative entity that invents new things, including life, but without the necessity of something like a god, especially not one who is pulling strings from behind the curtain. He said that evolution must, as the creationists say, work in a goal-directed way but disagreed with their view that it must necessarily be the hand of god that imposes these goals onto the stage of life.

Question: Popper disagreed with creationists that whose hand must be directing evolution?
Answer: god.

Buddhism /ˈbudɪzəm/ is a nontheistic religion[note 1] or philosophy (Sanskrit: धर्म dharma; Pali: धम्म dhamma) that encompasses a variety of traditions, beliefs and spiritual practices largely based on teachings attributed to Gautama Buddha, commonly known as the Buddha ("the awakened one"). According to Buddhist tradition, the Buddha lived and taught in the eastern part of the Indian subcontinent, present-day Nepal sometime between the 6th and 4th centuries BCE.[note 1] He is recognized by Buddhists as an awakened or enlightened teacher who shared his insights to help sentient beings end their suffering through the elimination of ignorance and craving. Buddhists believe that this is accomplished through the direct understanding and perception of dependent origination and the Four Noble Truths.

The Arthashastra and the Edicts of Ashoka are the primary written records of the Mauryan times. Archaeologically, this period falls into the era of Northern Black Polished Ware (NBPW). The Mauryan Empire was based on a modern and efficient economy and society. However, the sale of merchandise was closely regulated by the government. Although there was no banking in the Mauryan society, usury was customary. A significant amount of written records on slavery are found, suggesting a prevalence thereof. During this period, a high quality steel called Wootz steel was developed in south India and was later exported to China and Arabia.

During the Risorgimento, proponents of Italian republicanism and Italian nationalism, such as Alessandro Manzoni, stressed the importance of establishing a uniform national language in order to better create an Italian national identity. With the unification of Italy in the 1860s, standard Italian became the official national language of the new Italian state, while the various unofficial regional languages of Italy gradually became regarded as subordinate "dialects" to Italian, increasingly associated negatively with lack of education or provincialism. However, at the time of the Italian Unification, standard Italian still existed mainly as a literary language, and only 2.5% of Italy's population could speak standard Italian.

Question: What percentage of Italians spoke standard Italian when Italy was first unified?
Answer: 2.5%.

Traditionally, Section 1983 was of limited use for a state prisoner under sentence of death because the Supreme Court has held that habeas corpus, not Section 1983, is the only vehicle by which a state prisoner can challenge his judgment of death. In the 2006 Hill v. McDonough case, however, the United States Supreme Court approved the use of Section 1983 as a vehicle for challenging a state's method of execution as cruel and unusual punishment in violation of the Eighth Amendment. The theory is that a prisoner bringing such a challenge is not attacking directly his judgment of death, but rather the means by which that the judgment will be carried out. Therefore, the Supreme Court held in the Hill case that a prisoner can use Section 1983 rather than habeas corpus to bring the lawsuit. Yet, as Clarence Hill's own case shows, lower federal courts have often refused to hear suits challenging methods of execution on the ground that the prisoner brought the claim too late and only for the purposes of delay. Further, the Court's decision in Baze v. Rees, upholding a lethal injection method used by many states, has drastically narrowed the opportunity for relief through Section 1983.

Question: In what case did the Supreme Court allow Section 1983 to be used to challenge a method of execution?
Answer: Hill v. McDonough.

Trading in influence, or influence peddling, refers a person selling his/her influence over the decision making process to benefit a third party (person or institution). The difference with bribery is that this is a tri-lateral relation. From a legal point of view, the role of the third party (who is the target of the influence) does not really matter although he/she can be an accessory in some instances. It can be difficult to make a distinction between this form of corruption and some forms of extreme and loosely regulated lobbying where for instance law- or decision-makers can freely "sell" their vote, decision power or influence to those lobbyists who offer the highest compensation, including where for instance the latter act on behalf of powerful clients such as industrial groups who want to avoid the passing of specific environmental, social, or other regulations perceived as too stringent, etc. Where lobbying is (sufficiently) regulated, it becomes possible to provide for a distinctive criteria and to consider that trading in influence involves the use of "improper influence", as in article 12 of the Criminal Law Convention on Corruption (ETS 173) of the Council of Europe.

Resource mismanagement is a particular problem with NPOs because the employees are not accountable to anybody with a direct stake in the organization. For example, an employee may start a new program without disclosing its complete liabilities. The employee may be rewarded for improving the NPO's reputation, making other employees happy, and attracting new donors. Liabilities promised on the full faith and credit of the organization but not recorded anywhere constitute accounting fraud. But even indirect liabilities negatively affect the financial sustainability of the NPO, and the NPO will have financial problems unless strict controls are instated. Some commentators have also argued that receiving significant funding from large for-profit corporations can ultimately alter the NPO's functions.

Question: What can a large influx of money from a for-profit company do to an organization?
Answer: alter the NPO's functions.

At the age of 21 he settled in Paris. Thereafter, during the last 18 years of his life, he gave only some 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and teaching piano, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his musical contemporaries, including Robert Schumann. In 1835 he obtained French citizenship. After a failed engagement to Maria Wodzińska, from 1837 to 1847 he maintained an often troubled relationship with the French writer George Sand. A brief and unhappy visit to Majorca with Sand in 1838–39 was one of his most productive periods of composition. In his last years, he was financially supported by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. Through most of his life, Chopin suffered from poor health. He died in Paris in 1849, probably of tuberculosis.

After secession, some North Carolinians refused to support the Confederacy. Some of the yeoman farmers in the state's mountains and western Piedmont region remained neutral during the Civil War, while some covertly supported the Union cause during the conflict. Approximately 2,000 North Carolinians from western North Carolina enlisted in the Union Army and fought for the North in the war. Two additional Union Army regiments were raised in the coastal areas of the state, which were occupied by Union forces in 1862 and 1863. Numerous slaves escaped to Union lines, where they became essentially free.

The modern Greek theatre was born after the Greek independence, in the early 19th century, and initially was influenced by the Heptanesean theatre and melodrama, such as the Italian opera. The Nobile Teatro di San Giacomo di Corfù was the first theatre and opera house of modern Greece and the place where the first Greek opera, Spyridon Xyndas' The Parliamentary Candidate (based on an exclusively Greek libretto) was performed. During the late 19th and early 20th century, the Athenian theatre scene was dominated by revues, musical comedies, operettas and nocturnes and notable playwrights included Spyridon Samaras, Dionysios Lavrangas, Theophrastos Sakellaridis and others.

The enclosed compound of the Narayanhity Palace Museum is in the north-central part of Kathmandu. "Narayanhity" comes from Narayana, a form of the Hindu god Lord Vishnu, and Hiti, meaning "water spout" (Vishnu's temple is located opposite the palace, and the water spout is located east of the main entrance to the precinct). Narayanhity was a new palace, in front of the old palace built in 1915, and was built in 1970 in the form of a contemporary Pagoda. It was built on the occasion of the marriage of King Birenda Bir Bikram Shah, then heir apparent to the throne. The southern gate of the palace is at the crossing of Prithvipath and Darbar Marg roads. The palace area covers (30 hectares (74 acres)) and is fully secured with gates on all sides. This palace was the scene of the Nepali royal massacre. After the fall of the monarchy, it was converted to a museum.

One facet of the changing attitude toward Korea and whether to get involved was Japan. Especially after the fall of China to the Communists, U.S. East Asian experts saw Japan as the critical counterweight to the Soviet Union and China in the region. While there was no United States policy that dealt with South Korea directly as a national interest, its proximity to Japan increased the importance of South Korea. Said Kim: "The recognition that the security of Japan required a non-hostile Korea led directly to President Truman's decision to intervene... The essential point... is that the American response to the North Korean attack stemmed from considerations of US policy toward Japan."

The predominant educational psychology from the 1750s onward, especially in northern European countries was associationism, the notion that the mind associates or dissociates ideas through repeated routines. In addition to being conducive to Enlightenment ideologies of liberty, self-determination and personal responsibility, it offered a practical theory of the mind that allowed teachers to transform longstanding forms of print and manuscript culture into effective graphic tools of learning for the lower and middle orders of society. Children were taught to memorize facts through oral and graphic methods that originated during the Renaissance.

Question: How can associationism be defined?
Answer: the notion that the mind associates or dissociates ideas through repeated routines.

Unlike other data cables (e.g., Ethernet, HDMI), each end of a USB cable uses a different kind of connector; a Type-A or a Type-B. This kind of design was chosen to prevent electrical overloads and damaged equipment, as only the Type-A socket provides power. There are cables with Type-A connectors on both ends, but they should be used carefully. Therefore, in general, each of the different "sizes" requires four different connectors; USB cables have the Type-A and Type-B plugs, and the corresponding receptacles are on the computer or electronic device. In common practice, the Type-A connector is usually the full size, and the Type-B side can vary as needed.

During the 12th century, the institutions of central government, which had hitherto accompanied the royal English court as it moved around the country, grew in size and sophistication and became increasingly fixed in one place. In most cases this was Westminster, although the royal treasury, having been moved from Winchester, came to rest in the Tower. While the City of Westminster developed into a true capital in governmental terms, its distinct neighbour, the City of London, remained England's largest city and principal commercial centre, and it flourished under its own unique administration, the Corporation of London. In 1100, its population was around 18,000; by 1300 it had grown to nearly 100,000.

More contemporary views along the evolutionary psychology spectrum posit that both basic emotions and social emotions evolved to motivate (social) behaviors that were adaptive in the ancestral environment. Current research[citation needed] suggests that emotion is an essential part of any human decision-making and planning, and the famous distinction made between reason and emotion is not as clear as it seems. Paul D. MacLean claims that emotion competes with even more instinctive responses, on one hand, and the more abstract reasoning, on the other hand. The increased potential in neuroimaging has also allowed investigation into evolutionarily ancient parts of the brain. Important neurological advances were derived from these perspectives in the 1990s by Joseph E. LeDoux and António Damásio.

Several other types of capacitor are available for specialist applications. Supercapacitors store large amounts of energy. Supercapacitors made from carbon aerogel, carbon nanotubes, or highly porous electrode materials, offer extremely high capacitance (up to 5 kF as of 2010[update]) and can be used in some applications instead of rechargeable batteries. Alternating current capacitors are specifically designed to work on line (mains) voltage AC power circuits. They are commonly used in electric motor circuits and are often designed to handle large currents, so they tend to be physically large. They are usually ruggedly packaged, often in metal cases that can be easily grounded/earthed. They also are designed with direct current breakdown voltages of at least five times the maximum AC voltage.
