Barcelona is one of three founding members of the Primera Division that have never been relegated from the top division, along with Athletic Bilbao and Real Madrid. In 2009, Barcelona became the first Spanish club to win the continental treble consisting of La Liga, Copa del Rey, and the UEFA Champions League, and also became the first football club to win six out of six competitions in a single year, completing the sextuple in also winning the Spanish Super Cup, UEFA Super Cup and FIFA Club World Cup. In 2011, the club became European champions again and won five trophies. This Barcelona team, which reached a record six consecutive Champions League semi-finals and won 14 trophies in just four years under Pep Guardiola, is considered by some in the sport to be the greatest team of all time. In June 2015, Barcelona became the first European club in history to achieve the continental treble twice.
Besides Barcelona and Real Madrid, what other team has remained in the Primera Division?
Athletic Bilbao

Input: Gramophone record
Electrical recording preceded electrical home reproduction because of the initial high cost of the new system. In 1925, the Victor company introduced the Victor Orthophonic Victrola, an acoustical record player that was specifically designed to play electrically recorded discs, as part of a line that also included electrically reproducing Electrolas. The acoustical Orthophonics ranged in price from US$95 to US$300, depending on cabinetry; by comparison, the cheapest Electrola cost US$650, the price of a new Ford automobile in an era when clerical jobs paid about $20 a week.

What year was the Victor Orthophonic Victrola released?
Output: 1925

Input: Article: In a video posted on July 21, 2009, YouTube software engineer Peter Bradshaw announced that YouTube users can now upload 3D videos. The videos can be viewed in several different ways, including the common anaglyph (cyan/red lens) method which utilizes glasses worn by the viewer to achieve the 3D effect. The YouTube Flash player can display stereoscopic content interleaved in rows, columns or a checkerboard pattern, side-by-side or anaglyph using a red/cyan, green/magenta or blue/yellow combination. In May 2011, an HTML5 version of the YouTube player began supporting side-by-side 3D footage that is compatible with Nvidia 3D Vision.

Article: Vocal music in the Renaissance is noted for the flourishing of an increasingly elaborate polyphonic style. The principal liturgical forms which endured throughout the entire Renaissance period were masses and motets, with some other developments towards the end, especially as composers of sacred music began to adopt secular forms (such as the madrigal) for their own designs. Towards the end of the period, the early dramatic precursors of opera such as monody, the madrigal comedy, and the intermedio are seen.

Question: What liturgical form besides motets endured throughout the entire Renaissance period?
Ans: masses

Here is a question about this article: Political and religious animosity against Jehovah's Witnesses has at times led to mob action and government oppression in various countries. Their doctrine of political neutrality and their refusal to serve in the military has led to imprisonment of members who refused conscription during World War II and at other times where national service has been compulsory. In 1933, there were approximately 20,000 Jehovah's Witnesses in Germany, of whom about 10,000 were later imprisoned. Of those, 2000 were sent to Nazi concentration camps, where they were identified by purple triangles; as many as 1200 died, including 250 who were executed. In Canada, Jehovah's Witnesses were interned in camps along with political dissidents and people of Chinese and Japanese descent. In the former Soviet Union, about 9,300 Jehovah's Witnesses were deported to Siberia as part of Operation North in April 1951. Their religious activities are currently banned or restricted in some countries, including China, Vietnam and some Islamic states.
What is the answer to this question: Why have Jehovah's Witnesses sometimes been imprisoned?
****
So... doctrine of political neutrality and their refusal to serve in the military

Article: Notably, a statute does not disappear automatically merely because it has been found unconstitutional; it must be deleted by a subsequent statute. Many federal and state statutes have remained on the books for decades after they were ruled to be unconstitutional. However, under the principle of stare decisis, no sensible lower court will enforce an unconstitutional statute, and any court that does so will be reversed by the Supreme Court. Conversely, any court that refuses to enforce a constitutional statute (where such constitutionality has been expressly established in prior cases) will risk reversal by the Supreme Court.

Question: What must happen to a statute for it to become unconstitutional?
Ans:
it must be deleted
