Input: Article: The soft AC format may soon be facing the demographic pressures that the jazz and big band formats faced in the 1960s and 1970s and that the oldies format is starting to face today, with the result that one may hear soft AC less on over-the-air radio and more on satellite radio systems in coming years. Much of the music and artists that were traditionally played on soft AC stations have been relegated to the adult standards format, which is itself disappearing because of aging demographics. Some soft AC stations have found a niche by incorporating more oldies into their playlists and are more open to playing softer songs that fit the "traditional" definition of AC.

Now answer this question: Why are adult standards format radio stations declining?

Output: aging demographics

Input: Article: Brass, which is an alloy of copper and zinc, has been used since at least the 10th century BC in Judea and by the 7th century BC in Ancient Greece. Zinc metal was not produced on a large scale until the 12th century in India and was unknown to Europe until the end of the 16th century. The mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, as early as the 9th century AD when a distillation process was employed to make pure zinc. Alchemists burned zinc in air to form what they called "philosopher's wool" or "white snow".

Now answer this question: What two metals are mixed to create Brass?

Output: copper and zinc

Input: Article: Also with respect to copyright, the American film industry helped to change the social construct of intellectual property via its trade organization, the Motion Picture Association of America. In amicus briefs in important cases, in lobbying before Congress, and in its statements to the public, the MPAA has advocated strong protection of intellectual-property rights. In framing its presentations, the association has claimed that people are entitled to the property that is produced by their labor. Additionally Congress's awareness of the position of the United States as the world's largest producer of films has made it convenient to expand the conception of intellectual property. These doctrinal reforms have further strengthened the industry, lending the MPAA even more power and authority.

Now answer this question: Which country is the world's largest producer of films?

Output:
United States
