Context and question: On March 30, 2015, it was announced that Beyonce is a co-owner, with various other music artists, in the music streaming service Tidal. The service specialises in lossless audio and high definition music videos. Beyonce's husband Jay Z acquired the parent company of Tidal, Aspiro, in the first quarter of 2015. Including Beyonce and Jay-Z, sixteen artist stakeholders (such as Kanye West, Rihanna, Madonna, Chris Martin, Nicki Minaj and more) co-own Tidal, with the majority owning a 3% equity stake. The idea of having an all artist owned streaming service was created by those involved to adapt to the increased demand for streaming within the current music industry, and to rival other streaming services such as Spotify, which have been criticised for their low payout of royalties. "The challenge is to get everyone to respect music again, to recognize its value", stated Jay-Z on the release of Tidal.
Who acquired the parent company of the music service Beyonce owns part of?
Answer: Jay Z
Context and question: The first British patent for the use of asphalt/bitumen was 'Cassell's patent asphalte or bitumen' in 1834. Then on 25 November 1837, Richard Tappin Claridge patented the use of Seyssel asphalt (patent #7849), for use in asphalte pavement, having seen it employed in France and Belgium when visiting with Frederick Walter Simms, who worked with him on the introduction of asphalt to Britain. Dr T. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement (in 1836)". Indeed, mastic pavements had been previously employed at Vauxhall by a competitor of Claridge, but without success.
In 1845 Richard Tappin Claridge patented the use of what?
Answer: unanswerable
Context and question: Yale has a history of difficult and prolonged labor negotiations, often culminating in strikes. There have been at least eight strikes since 1968, and The New York Times wrote that Yale has a reputation as having the worst record of labor tension of any university in the U.S. Yale's unusually large endowment exacerbates the tension over wages. Moreover, Yale has been accused of failing to treat workers with respect. In a 2003 strike, however, the university claimed that more union employees were working than striking. Professor David Graeber was 'retired' after he came to the defense of a student who was involved in campus labor issues.
How many strikes has Yale had since 1986?
Answer:
unanswerable
