Input: Read this: The BYU Ballroom Dance Company is known as one of the best formation ballroom dance teams in the world, having won the U.S. National Formation Dance Championship every year since 1982. BYU's Ballroom dance team has won first place in Latin or Standard (or both) many times when they have competed at the Blackpool Dance Festival, and they were the first U.S. team to win the formation championships at the famed British Championships in Blackpool, England in 1972 . The NDCA National DanceSport championships have been held at BYU for several years, and BYU holds dozens of ballroom dance classes each semester and is consequently the largest collegiate ballroom dance program in the world. In addition, BYU has a number of other notable dance teams and programs. These teams include the Theatre Ballet, Contemporary Dance Theatre, Living Legends, and International Folk Dance Ensemble. The Living Legends perform Latin, Native American, and Polynesian dancing. BYU boasts one of the largest dance departments in the nation. Many students from all different majors across campus participate in various dance classes each semester.
Question: Who has won the U.S. National Formation Dance Championship every year since 1972?

Output: unanswerable


QUES: The softness of copper partly explains its high electrical conductivity (59.6×106 S/m) and thus also high thermal conductivity, which are the second highest (to silver) among pure metals at room temperature. This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal. The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively. As with other metals, if copper is placed against another metal, galvanic corrosion will occur.

What occurs when copper is placed apart from another metal?
What is the answer?

QUES: The U.S. Digital Millennium Copyright Act (1998) and the European E-Commerce Directive (2000) provide online intermediaries with limited statutory immunity from liability for copyright infringement. Online intermediaries hosting content that infringes copyright are not liable, so long as they do not know about it and take actions once the infringing content is brought to their attention. In U.S. law this is characterized as "safe harbor" provisions. Under European law, the governing principles for Internet Service Providers are "mere conduit", meaning that they are neutral 'pipes' with no knowledge of what they are carrying; and 'no obligation to monitor' meaning that they cannot be given a general mandate by governments to monitor content. These two principles are a barrier for certain forms of online copyright enforcement and they were the reason behind an attempt to amend the European Telecoms Package in 2009 to support new measures against copyright infringement.
What is it called when intermediaries cannot be given an order by governments to monitor what happens on their services?

ANS: no obligation to monitor


Players may only be transferred during transfer windows that are set by the Football Association. The two transfer windows run from the last day of the season to 31 August and from 31 December to 31 January. Player registrations cannot be exchanged outside these windows except under specific licence from the FA, usually on an emergency basis. As of the 2010–11 season, the Premier League introduced new rules mandating that each club must register a maximum 25-man squad of players aged over 21, with the squad list only allowed to be changed in transfer windows or in exceptional circumstances. This was to enable the 'home grown' rule to be enacted, whereby the League would also from 2010 require at least 8 of the named 25 man squad to be made up of 'home-grown players'.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When are the transfer windows?
Ah, so.. The two transfer windows run from the last day of the season to 31 August and from 31 December to 31 January.


Question: In 1926 Joseph P. Maxwell and Henry C. Harrison from Bell Telephone Laboratories disclosed that the recording pattern of the Western Electric "rubber line" magnetic disc cutter had a constant velocity characteristic. This meant that as frequency increased in the treble, recording amplitude decreased. Conversely, in the bass as frequency decreased, recording amplitude increased. Therefore, it was necessary to attenuate the bass frequencies below about 250 Hz, the bass turnover point, in the amplified microphone signal fed to the recording head. Otherwise, bass modulation became excessive and overcutting took place into the next record groove. When played back electrically with a magnetic pickup having a smooth response in the bass region, a complementary boost in amplitude at the bass turnover point was necessary. G. H. Miller in 1934 reported that when complementary boost at the turnover point was used in radio broadcasts of records, the reproduction was more realistic and many of the musical instruments stood out in their true form.
Try to answer this question if possible: What is found when a complementary boost is used at the bass turnover point?
Answer: reproduction was more realistic


Context and question: The Human Development Index (HDI) is a composite statistic of life expectancy, education, and income per capita indicators, which are used to rank countries into four tiers of human development. A country scores higher HDI when the life expectancy at birth is longer, the education period is longer, and the income per capita is higher. The HDI was developed by the Pakistani economist Mahbub ul Haq, often framed in terms of whether people are able to "be" and "do" desirable things in their life, and was published by the United Nations Development Programme.
Does a low ranking on the HDI indicate shorter or longer life expectancy?
Answer:
unanswerable
