Problem: Miami is also considered a "hot spot" for dance music, Freestyle, a style of dance music popular in the 80's and 90's heavily influenced by Electro, hip-hop, and disco. Many popular Freestyle acts such as Pretty Tony, Debbie Deb, Stevie B, and Expose, originated in Miami. Indie/folk acts Cat Power and Iron & Wine are based in the city, while alternative hip hop artist Sage Francis, electro artist Uffie, and the electroclash duo Avenue D were born in Miami, but musically based elsewhere. Also, ska punk band Against All Authority is from Miami, and rock/metal bands Nonpoint and Marilyn Manson each formed in neighboring Fort Lauderdale. Cuban American female recording artist, Ana Cristina, was born in Miami in 1985.
Along with Cat Power, what indie/folk musician is based in Miami?
The answer is the following: Iron & Wine

Problem: During the tumultuous 14th century, disputes within the leadership of the Church led to the Avignon Papacy of 130578, also called the "Babylonian Captivity of the Papacy" (a reference to the Babylonian captivity of the Jews), and then to the Great Schism, lasting from 1378 to 1418, when there were two and later three rival popes, each supported by several states. Ecclesiastical officials convened at the Council of Constance in 1414, and in the following year the council deposed one of the rival popes, leaving only two claimants. Further depositions followed, and in November 1417 the council elected Martin V (pope 141731) as pope.
How many popes existed simultaneously after the Council of Constance?
The answer is the following: two

Problem: Comparison of a back-translation with the original text is sometimes used as a check on the accuracy of the original translation, much as the accuracy of a mathematical operation is sometimes checked by reversing the operation. But the results of such reverse-translation operations, while useful as approximate checks, are not always precisely reliable. Back-translation must in general be less accurate than back-calculation because linguistic symbols (words) are often ambiguous, whereas mathematical symbols are intentionally unequivocal.
How are mathematical operations checked?
The answer is the following: by reversing the operation

Problem: The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders. Moving to Hammondsport, the group then designed and built the Red Wing, framed in bamboo and covered in red silk and powered by a small air-cooled engine. On March 12, 1908, over Keuka Lake, the biplane lifted off on the first public flight in North America.[N 24] [N 25] The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). One of the AEA's inventions, a practical wingtip form of the aileron, was to become a standard component on all aircraft. [N 26] The White Wing and June Bug were to follow and by the end of 1908, over 150 flights without mishap had been accomplished. However, the AEA had depleted its initial reserves and only a $15,000 grant from Mrs. Bell allowed it to continue with experiments. Lt. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer, Virginia, on September 17, 1908.
What material was the Red Wing's frame made of?
The answer is the following:
bamboo
