Problem: YouTube:

Organizations including Viacom, Mediaset, and the English Premier League have filed lawsuits against YouTube, claiming that it has done too little to prevent the uploading of copyrighted material. Viacom, demanding $1 billion in damages, said that it had found more than 150,000 unauthorized clips of its material on YouTube that had been viewed "an astounding 1.5 billion times". YouTube responded by stating that it "goes far beyond its legal obligations in assisting content owners to protect their works".

Who found that their content had been viewed "an astounding 1 billion times?"

A: unanswerable


Problem: The Council does not have executive powers but meets biannually to discuss issues of mutual importance. Similarly, the Parliamentary Assembly has no legislative powers but investigates and collects witness evidence from the public on matters of mutual concern to its members. Reports on its findings are presented to the Governments of Ireland and the United Kingdom. During the February 2008 meeting of the British–Irish Council, it was agreed to set up a standing secretariat that would serve as a permanent 'civil service' for the Council. Leading on from developments in the British–Irish Council, the chair of the British–Irish Inter-Parliamentary Assembly, Niall Blaney, has suggested that the body should shadow the British–Irish Council's work.
What does the British-Irish Council do?

Answer: investigates and collects witness evidence

Context and question: Acid house arose from Chicago artists' experiments with the squelchy Roland TB-303 bass synthesizer, and the style's origins on vinyl is generally cited as Phuture's "Acid Tracks" (1987). Phuture, a group founded by Nathan "DJ Pierre" Jones, Earl "Spanky" Smith Jr., and Herbert "Herb J" Jackson, is credited with having been the first to use the TB-303 in the house music context. The group's 12-minute "Acid Tracks" was recorded to tape and was played by DJ Ron Hardy at the Music Box, where Hardy was resident DJ. Hardy once played it four times over the course of an evening until the crowd responded favorably. The track also utilized a Roland TR-707 drum machine.
When was Phuture's "Acid Hardy" released?
Answer: unanswerable


Question: Each trace consists of a flat, narrow part of the copper foil that remains after etching. The resistance, determined by width and thickness, of the traces must be sufficiently low for the current the conductor will carry. Power and ground traces may need to be wider than signal traces. In a multi-layer board one entire layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave circuits, transmission lines can be laid out in the form of stripline and microstrip with carefully controlled dimensions to assure a consistent impedance. In radio-frequency and fast switching circuits the inductance and capacitance of the printed circuit board conductors become significant circuit elements, usually undesired; but they can be used as a deliberate part of the circuit design, obviating the need for additional discrete components.
Is there an answer to this question: What type of circuits use a stripline and microstrip format?

Answer: microwave circuits


Question: Football gameday traditions During home games, activities occur all around campus and different dorms decorate their halls with a traditional item (e.g. Zahm House's two-story banner). Traditional activities begin at the stroke of midnight with the Drummers' Circle. This tradition involves the drum line of the Band of the Fighting Irish and ushers in the rest of the festivities that will continue the rest of the gameday Saturday. Later that day, the trumpet section will play the Notre Dame Victory March and the Notre Dame Alma Mater under the dome. The band entire will play a concert at the steps of Bond Hall, from where they will march into Notre Dame Stadium, leading fans and students alike across campus to the game.
Is there an answer to this question: From where does the Band of the Fighting Irish lead a march to the Notre Dame Stadium for football home games?
