Article: Exchanging "+" and "−" in the expression, i.e. permuting the two solutions of the equation can be viewed as a (very simple) group operation. Similar formulae are known for cubic and quartic equations, but do not exist in general for degree 5 and higher. Abstract properties of Galois groups associated with polynomials (in particular their solvability) give a criterion for polynomials that have all their solutions expressible by radicals, i.e. solutions expressible using solely addition, multiplication, and roots similar to the formula above.

Question: What are used to express the solutions of polynomials?
Ans: radicals


Here is a question about this article: Some of the later writers about the show were more positive, Michael Slezak, again of Entertainment Weekly, thought that "for all its bloated, synthetic, product-shilling, money-making trappings, Idol provides a once-a-year chance for the average American to combat the evils of today's music business." Singer Sheryl Crow, who was later to act as a mentor on the show, however took the view that the show "undermines art in every way and promotes commercialism". Pop music critic Ann Powers nevertheless suggested that Idol has "reshaped the American songbook", "led us toward a new way of viewing ourselves in relationship to mainstream popular culture", and connects "the classic Hollywood dream to the multicentered popular culture of the future." Others focused on the personalities in the show; Ramin Setoodeh of Newsweek accused judge Simon Cowell's cruel critiques in the show of helping to establish in the wider world a culture of meanness, that "Simon Cowell has dragged the rest of us in the mud with him." Some such as singer John Mayer disparaged the contestants, suggesting that those who appeared on Idol are not real artists with self-respect.
What is the answer to this question: What magazine does Ramin Wetoodeh write for? 
****
So... Newsweek


The problem: Answer a question about this article:
Miami is noted as "the only major city in the United States conceived by a woman, Julia Tuttle", a local citrus grower and a wealthy Cleveland native. The Miami area was better known as "Biscayne Bay Country" in the early years of its growth. In the late 19th century, reports described the area as a promising wilderness. The area was also characterized as "one of the finest building sites in Florida." The Great Freeze of 1894–95 hastened Miami's growth, as the crops of the Miami area were the only ones in Florida that survived. Julia Tuttle subsequently convinced Henry Flagler, a railroad tycoon, to expand his Florida East Coast Railway to the region, for which she became known as "the mother of Miami." Miami was officially incorporated as a city on July 28, 1896 with a population of just over 300. It was named for the nearby Miami River, derived from Mayaimi, the historic name of Lake Okeechobee.
Prior to the naming of Miami, what was the area around Miami called?
****
The answer: Biscayne Bay Country


Problem: Please answer a question about the following article about Santa Monica, California:
Historical aspects of the Expo line route are noteworthy. It uses the right-of-way for the Santa Monica Air Line that provided electric-powered freight and passenger service between Los Angeles and Santa Monica beginning in the 1920s. Service was discontinued in 1953 but diesel-powered freight deliveries to warehouses along the route continued until March 11, 1988. The abandonment of the line spurred concerns within the community and the entire right-of-way was purchased from Southern Pacific by Los Angeles Metropolitan Transportation Authority. The line was built in 1875 as the steam-powered Los Angeles and Independence Railroad to bring mining ore to ships in Santa Monica harbor and as a passenger excursion train to the beach.
What year did the Santa Monica freight and passenger service stop running?
A: 1953

Ibn Sina created an extensive corpus of works during what is commonly known as the Islamic Golden Age, in which the translations of Greco-Roman, Persian, and Indian texts were studied extensively. Greco-Roman (Mid- and Neo-Platonic, and Aristotelian) texts translated by the Kindi school were commented, redacted and developed substantially by Islamic intellectuals, who also built upon Persian and Indian mathematical systems, astronomy, algebra, trigonometry and medicine. The Samanid dynasty in the eastern part of Persia, Greater Khorasan and Central Asia as well as the Buyid dynasty in the western part of Persia and Iraq provided a thriving atmosphere for scholarly and cultural development. Under the Samanids, Bukhara rivaled Baghdad as a cultural capital of the Islamic world.

What school translated Greco-Roman texts during the Islamic Golden Age?
Answer: the Kindi school


The first political factions, cohering around a basic, if fluid, set of principles emerged from the Exclusion Crisis and Glorious Revolution in late-17th-century England. The Whigs supported Protestant constitutional monarchy against absolute rule and the Tories, originating in the Royalist (or "Cavalier") faction of the English Civil War, were conservative royalist supporters of a strong monarchy as a counterbalance to the republican tendencies of Whigs, who were the dominant political faction for most of the first half of the 18th century; they supported the Hanoverian succession of 1715 against the Jacobite supporters of the deposed Roman Catholic Stuart dynasty and were able to purge Tory politicians from important government positions after the failed Jacobite rising of 1715. The leader of the Whigs was Robert Walpole, who maintained control of the government in the period 1721–1742; his protégé was Henry Pelham (1743–1754).
Who was the dominate political party for the first half of the 18th century?
Whigs
