Question: In the beginning, racial classifications that identified race were inherently suspect and subject to strict scrutiny. These classifications would only be upheld if necessary to promote a compelling governmental interest. Later the U.S. Supreme Court decided that racial classifications that benefited underrepresented minorities were to only be upheld if necessary and promoted a compelling governmental purpose. (See Richmond v. J.A. Croson Co.) There is no clear guidance about when government action is not "compelling", and such rulings are rare.
Is there an answer to this question: What was the only situation in which a racial classification could be considered acceptable?

Answer: necessary to promote a compelling governmental interest

Question: After the end of the late Middle Ages period, the Renaissance would spread unevenly over continental Europe from the southern European region. The intellectual transformation of the Renaissance is viewed as a bridge between the Middle Ages and the Modern era. Europeans would later begin an era of world discovery. Combined with the influx of classical ideas was the invention of printing which facilitated dissemination of the printed word and democratized learning. These two things would lead to the Protestant Reformation. Europeans also discovered new trading routes, as was the case with Columbus's travel to the Americas in 1492, and Vasco da Gama's circumnavigation of Africa and India in 1498. Their discoveries strengthened the economy and power of European nations.
Is there an answer to this question: What historical era is viewed as a bridge between the Middle Ages and the Modern Era?

Answer: the Renaissance

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.
Is there an answer to this question: When was it discovered Beyonce was a co-owner of the music service, Tidal?
