Problem: Protestantism:

Various ecumenical movements have attempted cooperation or reorganization of the various divided Protestant denominations, according to various models of union, but divisions continue to outpace unions, as there is no overarching authority to which any of the churches owe allegiance, which can authoritatively define the faith. Most denominations share common beliefs in the major aspects of the Christian faith while differing in many secondary doctrines, although what is major and what is secondary is a matter of idiosyncratic belief.

What types of doctrines do denominations not agree on?
---
A: secondary

Problem: German cinema dates back to the very early years of the medium with the work of Max Skladanowsky. It was particularly influential during the years of the Weimar Republic with German expressionists such as Robert Wiene and Friedrich Wilhelm Murnau. The Nazi era produced mostly propaganda films although the work of Leni Riefenstahl still introduced new aesthetics in film. From the 1960s, New German Cinema directors such as Volker Schlondorff, Werner Herzog, Wim Wenders, Rainer Werner Fassbinder placed West-German cinema back onto the international stage with their often provocative films, while the Deutsche Film-Aktiengesellschaft controlled film production in the GDR.
What did Murnau produce during the Nazi era?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The opening years of the 1980s saw a number of changes in personnel and direction of established hard rock acts, including the deaths of Bon Scott, the lead singer of AC/DC, and John Bonham, drummer with Led Zeppelin. Whereas Zeppelin broke up almost immediately afterwards, AC/DC pressed on, recording the album Back in Black (1980) with their new lead singer, Brian Johnson. It became the fifth-highest-selling album of all time in the US and the second-highest-selling album in the world. Black Sabbath had split with original singer Ozzy Osbourne in 1979 and replaced him with Ronnie James Dio, formerly of Rainbow, giving the band a new sound and a period of creativity and popularity beginning with Heaven and Hell (1980). Osbourne embarked on a solo career with Blizzard of Ozz (1980), featuring American guitarist Randy Rhoads. Some bands, such as Queen, moved away from their hard rock roots and more towards pop rock, while others, including Rush with Moving Pictures (1981), began to return to a hard rock sound. The creation of thrash metal, which mixed heavy metal with elements of hardcore punk from about 1982, particularly by Metallica, Anthrax, Megadeth and Slayer, helped to create extreme metal and further remove the style from hard rock, although a number of these bands or their members would continue to record some songs closer to a hard rock sound. Kiss moved away from their hard rock roots toward pop metal: firstly removing their makeup in 1983 for their Lick It Up album, and then adopting the visual and sound of glam metal for their 1984 release, Animalize, both of which marked a return to commercial success. Pat Benatar was one of the first women to achieve commercial success in hard rock, with three successive Top 5 albums between 1980 and 1982.
What AC/DC album became the fifth highest selling album in the US?
A: unanswerable

Context and question: Impermanence (Pali: anicca) expresses the Buddhist notion that all compounded or conditioned phenomena (all things and experiences) are inconstant, unsteady, and impermanent. Everything we can experience through our senses is made up of parts, and its existence is dependent on external conditions. Everything is in constant flux, and so conditions and the thing itself are constantly changing. Things are constantly coming into being, and ceasing to be. Since nothing lasts, there is no inherent or fixed nature to any object or experience. According to the doctrine of impermanence, life embodies this flux in the aging process, the cycle of rebirth (samsara), and in any experience of loss. The doctrine asserts that because things are impermanent, attachment to them is futile and leads to suffering (dukkha).
What is in a constant flux?
Answer: Everything

Question: After the incorporation of these states to the United States in the first half of the 19th century, the Spanish language was later reinforced in the country by the acquisition of Puerto Rico in 1898. Later waves of emigration from Mexico, Cuba, El Salvador and elsewhere in Hispanic America to the United States beginning in the second half of the 19th century to the present-day have strengthened the role of the Spanish language in the country. Today, Hispanics are one of the fastest growing demographics in the United States, thus increasing the use and importance of American Spanish in the United States.
Is there an answer to this question: What was incorporated to the united states in the first half of the 18th century?

Answer: unanswerable

Question: In May 2014, prior to the launch of YouTube's subscription-based Music Key service, the independent music trade organization Worldwide Independent Network alleged that YouTube was using non-negotiable contracts with independent labels that were "undervalued" in comparison to other streaming services, and that YouTube would block all music content from labels who do not reach a deal to be included on the paid service. In a statement to the Financial Times in June 2014, Robert Kyncl confirmed that YouTube would block the content of labels who do not negotiate deals to be included in the paid service "to ensure that all content on the platform is governed by its new contractual terms." Stating that 90% of labels had reached deals, he went on to say that "while we wish that we had [a] 100% success rate, we understand that is not likely an achievable goal and therefore it is our responsibility to our users and the industry to launch the enhanced music experience." The Financial Times later reported that YouTube had reached an aggregate deal with Merlin Networka trade group representing over 20,000 independent labels, for their inclusion in the service. However, YouTube itself has not confirmed the deal.
Is there an answer to this question: What reason did Robert Kyncl give in May 2014 for YouTube blocking content labels?
