question:
Why did using the method Bach didn't use, gain traction?, Context: The theories surrounding equal temperament began to be put in wider practice, especially as it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments. Although Bach did not use equal temperament, as a modern piano is generally tuned, changes in the temperaments from the meantone system, common at the time, to various temperaments that made modulation between all keys musically acceptable, made possible Bach's Well-Tempered Clavier.
answer:
it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments

question:
Which company was being sued in 1999 by Schwarzenegger for making claims regarding his steroid use?, Context: In 1999, Schwarzenegger sued Dr. Willi Heepe, a German doctor who publicly predicted his early death on the basis of a link between his steroid use and his later heart problems. As the doctor had never examined him personally, Schwarzenegger collected a US$10,000 libel judgment against him in a German court. In 1999, Schwarzenegger also sued and settled with The Globe, a U.S. tabloid which had made similar predictions about the bodybuilder's future health.
answer:
The Globe

question:
Was Viardot's comment real?, Context: With his health further deteriorating, Chopin desired to have a family member with him. In June 1849 his sister Ludwika came to Paris with her husband and daughter, and in September, supported by a loan from Jane Stirling, he took an apartment at Place Vendome 12. After 15 October, when his condition took a marked turn for the worse, only a handful of his closest friends remained with him, although Viardot remarked sardonically that "all the grand Parisian ladies considered it de rigueur to faint in his room."
answer:
sardonically
