Context and question: His opponents learned from Napoleon's innovations. The increased importance of artillery after 1807 stemmed from his creation of a highly mobile artillery force, the growth in artillery numbers, and changes in artillery practices. As a result of these factors, Napoleon, rather than relying on infantry to wear away the enemy's defenses, now could use massed artillery as a spearhead to pound a break in the enemy's line that was then exploited by supporting infantry and cavalry. McConachy rejects the alternative theory that growing reliance on artillery by the French army beginning in 1807 was an outgrowth of the declining quality of the French infantry and, later, France's inferiority in cavalry numbers. Weapons and other kinds of military technology remained largely static through the Revolutionary and Napoleonic eras, but 18th-century operational mobility underwent significant change.
What did Napoleon use as the initial means of breaking down enemy defenses, rather than the traditional reliance on infantry?
Answer: artillery

Problem: Queen (band):

Queen drew artistic influence from British rock acts of the 1960s and early 1970s, such as the Beatles, the Kinks, Cream, Led Zeppelin, Pink Floyd, the Who, Black Sabbath, Slade, Deep Purple, David Bowie, Genesis and Yes, in addition to American guitarist Jimi Hendrix, with Mercury also inspired by the gospel singer Aretha Franklin. May referred to the Beatles as being "our bible in the way they used the studio and they painted pictures and this wonderful instinctive use of harmonies." At their outset in the early 1970s, Queen's music has been characterised as "Led Zeppelin meets Yes" due to its combination of "acoustic/electric guitar extremes and fantasy-inspired multi-part song epics".

What gospel singer did Freddie Mercury cite as an inspiration?

A:
Aretha Franklin
