Problem: Democracy, social-contract theory, separation of powers, religious freedom, separation of church and state – these achievements of the Reformation and early Protestantism were elaborated on and popularized by Enlightenment thinkers. Some of the philosophers of the English, Scottish, German, and Swiss Enlightenment - Thomas Hobbes, John Locke, John Toland, David Hume, Gottfried Wilhelm Leibniz, Christian Wolff, Immanuel Kant, and Jean-Jacques Rousseau - had Protestant backgrounds. For example, John Locke, whose political thought was based on "a set of Protestant Christian assumptions", derived the equality of all humans, including the equality of the genders ("Adam and Eve"), from Genesis 1, 26-28. As all persons were created equally free, all governments needed "the consent of the governed." These Lockean ideas were fundamental to the United States Declaration of Independence, which also deduced human rights from the biblical belief in creation: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness."
What group popularized early Protestant teachings about separation of church and state?

Problem: Queen began their 1980s career with The Game. It featured the singles "Crazy Little Thing Called Love" and "Another One Bites the Dust", both of which reached number one in the US. After attending a Queen concert in Los Angeles, Michael Jackson suggested to Mercury backstage that "Another One Bites the Dust" be released as a single, and in October 1980 it spent three weeks at number one. The album topped the Billboard 200 for five weeks, and sold over four million copies in the US. It was also the first appearance of a synthesiser on a Queen album. Heretofore, their albums featured a distinctive "No Synthesisers!" sleeve note. The note is widely assumed to reflect an anti-synth, pro-"hard"-rock stance by the band, but was later revealed by producer Roy Thomas Baker to be an attempt to clarify that those albums' multi-layered solos were created with guitars, not synths, as record company executives kept assuming at the time. In September 1980, Queen performed three sold-out shows at Madison Square Garden. In 1980, Queen also released the soundtrack they had recorded for Flash Gordon. At the 1981 American Music Awards in January, "Another One Bites the Dust" won the award for Favorite Pop/Rock Single, and Queen were nominated for Favorite Pop/Rock Band, Duo, or Group.
Which Queen album kicked off the 1980s?
The answer is the following: The Game
