Article: In principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century. In practice, these are no longer the most accurate methods. The CODATA value quoted here is based on three watt-balance measurements of KJ2RK and one inter-laboratory determination of the molar volume of silicon, but is mostly determined by a 2007 watt-balance measurement made at the U.S. National Institute of Standards and Technology (NIST). Five other measurements by three different methods were initially considered, but not included in the final refinement as they were too imprecise to affect the result.

Question: One other measure involved the molar volume of what element?
Ans: silicon


Here is a question about this article: In 1980, when the stadium was in need of redesign to meet UEFA criteria, the club raised money by offering supporters the opportunity to inscribe their name on the bricks for a small fee. The idea was popular with supporters, and thousands of people paid the fee. Later this became the centre of controversy when media in Madrid picked up reports that one of the stones was inscribed with the name of long-time Real Madrid chairman and Franco supporter Santiago Bernabéu. In preparation for the 1992 Summer Olympics two tiers of seating were installed above the previous roofline. It has a current capacity of 99,354 making it the largest stadium in Europe.
What is the answer to this question: What name inscription was a center of controversy?
****
So... Santiago Bernabéu

Problem: Please answer a question about the following article about Asphalt:
Asphalt/bitumen is similar to the organic matter in carbonaceous meteorites. However, detailed studies have shown these materials to be distinct. The vast Alberta bitumen resources are believed to have started out as living material from marine plants and animals, mainly algae, that died millions of years ago when an ancient ocean covered Alberta. They were covered by mud, buried deeply over the eons, and gently cooked into oil by geothermal heat at a temperature of 50 to 150 °C (120 to 300 °F). Due to pressure from the rising of the Rocky Mountains in southwestern Alberta, 80 to 55 million years ago, the oil was driven northeast hundreds of kilometres into underground sand deposits left behind by ancient river beds and ocean beaches, thus forming the oil sands.
What did the Alberta bitumen mines begin as?
A: living material

West is among the most critically acclaimed artists of the twenty-first century, receiving praise from music critics, fans, fellow musicians, artists, and wider cultural figures for his work. AllMusic editor Jason Birchmeier writes of his impact, "As his career progressed throughout the early 21st century, West shattered certain stereotypes about rappers, becoming a superstar on his own terms without adapting his appearance, his rhetoric, or his music to fit any one musical mold." Jon Caramanic of The New York Times said that West has been "a frequent lightning rod for controversy, a bombastic figure who can count rankling two presidents among his achievements, along with being a reliably dyspeptic presence at award shows (when he attends them)." Village Voice Media senior editor Ben Westhoff dubbed him the greatest hip hop artist of all time, writing that "he's made the best albums and changed the game the most, and his music is the most likely to endure," while Complex called him the 21st century's "most important artist of any art form, of any genre." The Guardian has compared West to David Bowie, arguing that "there is nobody else who can sell as many records as West does (30m-odd album sales and counting) while remaining so resolutely experimental and capable of stirring things up culturally and politically."
Who said Kanye West was the greatest hip hop artist of all time?
