The problem: Answer a question about this article:
The discovery and isolation of radium in uranium ore (pitchblende) by Marie Curie sparked the development of uranium mining to extract the radium, which was used to make glow-in-the-dark paints for clock and aircraft dials. This left a prodigious quantity of uranium as a waste product, since it takes three tonnes of uranium to extract one gram of radium. This waste product was diverted to the glazing industry, making uranium glazes very inexpensive and abundant. Besides the pottery glazes, uranium tile glazes accounted for the bulk of the use, including common bathroom and kitchen tiles which can be produced in green, yellow, mauve, black, blue, red and other colors.
Along with red, blue, black, yellow and green, what was a notable color of uranium tile glaze?
****
The answer: mauve

The Liberal Party's organisation is dominated by the six state divisions, reflecting the party's original commitment to a federalised system of government (a commitment which was strongly maintained by all Liberal governments until 1983, but was to a large extent abandoned by the Howard Government, which showed strong centralising tendencies). Menzies deliberately created a weak national party machine and strong state divisions. Party policy is made almost entirely by the parliamentary parties, not by the party's rank-and-file members, although Liberal party members do have a degree of influence over party policy.
Who makes party policy?
****
The answer: almost entirely by the parliamentary parties, not by the party's rank-and-file members

In Chapter II, Darwin specifies that the distinction between species and varieties is arbitrary, with experts disagreeing and changing their decisions when new forms were found. He concludes that "a well-marked variety may be justly called an incipient species" and that "species are only strongly marked and permanent varieties". He argues for the ubiquity of variation in nature. Historians have noted that naturalists had long been aware that the individuals of a species differed from one another, but had generally considered such variations to be limited and unimportant deviations from the archetype of each species, that archetype being a fixed ideal in the mind of God. Darwin and Wallace made variation among individuals of the same species central to understanding the natural world.
What does Darwin believe about the differences between species and varieties?
****
The answer: is arbitrary

The problem: Answer a question about this article:
The record transfer fee for a Premier League player has risen steadily over the lifetime of the competition. Prior to the start of the first Premier League season Alan Shearer became the first British player to command a transfer fee of more than 3 million. The record rose steadily in the Premier League's first few seasons, until Alan Shearer made a record breaking 15 million move to Newcastle United in 1996. The three highest transfer in the sport's history had a Premier League club on the selling end, with Tottenham Hotspur selling Gareth Bale to Real Madrid for 85 million in 2013, Manchester United's sale of Cristiano Ronaldo to Real Madrid for 80 million in 2009, and Liverpool selling Luis Suarez to Barcelona for 75 million in 2014.
For how much did Tottenham Hotspur sell Gareth Bale to Real Madrid for in 2013?

85 million
