Question: The dates are generalizations, since the periods and eras overlap and the categories are somewhat arbitrary, to the point that some authorities reverse terminologies and refer to a common practice "era" comprising baroque, classical, and romantic "periods". For example, the use of counterpoint and fugue, which is considered characteristic of the Baroque era (or period), was continued by Haydn, who is classified as typical of the Classical era. Beethoven, who is often described as a founder of the Romantic era, and Brahms, who is classified as Romantic, also used counterpoint and fugue, but other characteristics of their music define their era.
Is there an answer to this question: Some authorities reverse terminologies to refer to the common practice period as a what?

Answer: era

Question: Virtually all console gaming systems of the previous generation used microprocessors developed by IBM. The Xbox 360 contains a PowerPC tri-core processor, which was designed and produced by IBM in less than 24 months. Sony's PlayStation 3 features the Cell BE microprocessor designed jointly by IBM, Toshiba, and Sony. IBM also provided the microprocessor that serves as the heart of Nintendo's new Wii U system, which debuted in 2012. The new Power Architecture-based microprocessor includes IBM's latest technology in an energy-saving silicon package. Nintendo's seventh-generation console, Wii, features an IBM chip codenamed Broadway. The older Nintendo GameCube utilizes the Gekko processor, also designed by IBM.
Is there an answer to this question: How long did it take for Nintendo to develop the PowerPC tri-core processor?

Answer: unanswerable

Question: The Feynman Lectures on Physics is perhaps his most accessible work for anyone with an interest in physics, compiled from lectures to Caltech undergraduates in 196164. As news of the lectures' lucidity grew, professional physicists and graduate students began to drop in to listen. Co-authors Robert B. Leighton and Matthew Sands, colleagues of Feynman, edited and illustrated them into book form. The work has endured and is useful to this day. They were edited and supplemented in 2005 with "Feynman's Tips on Physics: A Problem-Solving Supplement to the Feynman Lectures on Physics" by Michael Gottlieb and Ralph Leighton (Robert Leighton's son), with support from Kip Thorne and other physicists.
Is there an answer to this question: Once the popularity on the lectures grew, who began to attend?

Answer: professional physicists and graduate students

Question: On July 1, 2014, the University of Notre Dame and Under Armour reached an agreement in which Under Armour will provide uniforms, apparel,equipment, and monetary compensation to Notre Dame for 10 years. This contract, worth almost $100 million, is the most lucrative in the history of the NCAA. The university marching band plays at home games for most of the sports. The band, which began in 1846 and has a claim as the oldest university band in continuous existence in the United States, was honored by the National Music Council as a "Landmark of American Music" during the United States Bicentennial. The band regularly plays the school's fight song the Notre Dame Victory March, which was named as the most played and most famous fight song by Northern Illinois Professor William Studwell. According to College Fight Songs: An Annotated Anthology published in 1998, the "Notre Dame Victory March" ranks as the greatest fight song of all time.
Is there an answer to this question: Who currently provides uniforms to Notre Dame sport teams?

Answer:
Under Armour
