Problem: United States presidential election, 2004:

The 2004 election was the first to be affected by the campaign finance reforms mandated by the Bipartisan Campaign Reform Act of 2002 (also known as the McCainFeingold Bill for its sponsors in the United States Senate). Because of the Act's restrictions on candidates' and parties' fundraising, a large number of so-called 527 groups emerged. Named for a section of the Internal Revenue Code, these groups were able to raise large amounts of money for various political causes as long as they do not coordinate their activities with political campaigns. Examples of 527s include Swift Boat Veterans for Truth, MoveOn.org, the Media Fund, and America Coming Together. Many such groups were active throughout the campaign season. (There was some similar activity, although on a much lesser scale, during the 2000 campaign.)

What is one of the named 527 groups from the 2004 election?

A: MoveOn.org

Problem: Lasers emitting in the red region of the spectrum have been available since the invention of the ruby laser in 1960. In 1962 the red heliumneon laser was invented, and these two types of lasers were widely used in many scientific applications including holography, and in education. Red heliumneon lasers were used commercially in LaserDisc players. The use of red laser diodes became widespread with the commercial success of modern DVD players, which use a 660 nm laser diode technology. Today, red and red-orange laser diodes are widely available to the public in the form of extremely inexpensive laser pointers. Portable, high-powered versions are also available for various applications. More recently, 671 nm diode-pumped solid state (DPSS) lasers have been introduced to the market for all-DPSS laser display systems, particle image velocimetry, Raman spectroscopy, and holography.
What type of laser is used in Raman spectroscopy?

Answer: 671 nm diode-pumped solid state (DPSS) lasers

Context and question: The era of manufactured fibers began with the development of rayon in France in the 1890s. Rayon is derived from a natural cellulose and cannot be considered synthetic, but requires extensive processing in a manufacturing process, and led the less expensive replacement of more naturally derived materials. A succession of new synthetic fibers were introduced by the chemicals industry in the following decades. Acetate in fiber form was developed in 1924. Nylon, the first fiber synthesized entirely from petrochemicals, was introduced as a sewing thread by DuPont in 1936, followed by DuPont's acrylic in 1944. Some garments were created from fabrics based on these fibers, such as women's hosiery from nylon, but it was not until the introduction of polyester into the fiber marketplace in the early 1950s that the market for cotton came under threat. The rapid uptake of polyester garments in the 1960s caused economic hardship in cotton-exporting economies, especially in Central American countries, such as Nicaragua, where cotton production had boomed tenfold between 1950 and 1965 with the advent of cheap chemical pesticides. Cotton production recovered in the 1970s, but crashed to pre-1960 levels in the early 1990s.
What type of industry produced a growing chain of DuPont?
Answer: unanswerable

Question: In 1904, the steamship General Slocum caught fire in the East River, killing 1,021 people on board. In 1911, the Triangle Shirtwaist Factory fire, the city's worst industrial disaster, took the lives of 146 garment workers and spurred the growth of the International Ladies' Garment Workers' Union and major improvements in factory safety standards.
Is there an answer to this question: The growth of what organization was prompted by the Triangle Shirtwaist Factory fire?

Answer: International Ladies' Garment Workers' Union

Question: Many of the instruments used to perform medieval music still exist, but in different forms. Medieval instruments included the wood flute (which in the 21st century is made of metal), the recorder and plucked string instruments like the lute. As well, early versions of the organ, fiddle (or vielle), and trombone (called the sackbut) existed. Medieval instruments in Europe had most commonly been used singly, often self accompanied with a drone note, or occasionally in parts. From at least as early as the 13th century through the 15th century there was a division of instruments into haut (loud, shrill, outdoor instruments) and bas (quieter, more intimate instruments).
Is there an answer to this question: Medieval instrument in Europe were commonly used how?

Answer:
singly
