Problem: The most-commonly accepted theory is that these events were triggered by the onset of an ice age, in the Hirnantian faunal stage that ended the long, stable greenhouse conditions typical of the Ordovician. The ice age was probably not as long-lasting as once thought; study of oxygen isotopes in fossil brachiopods shows that it was probably no longer than 0.5 to 1.5 million years. The event was preceded by a fall in atmospheric carbon dioxide (from 7000ppm to 4400ppm) which selectively affected the shallow seas where most organisms lived. As the southern supercontinent Gondwana drifted over the South Pole, ice caps formed on it. Evidence of these ice caps have been detected in Upper Ordovician rock strata of North Africa and then-adjacent northeastern South America, which were south-polar locations at the time.
Oxygen from what kind of fossil were used to date the Hirnantian faunal stage?
The answer is the following: brachiopods

Problem: The post-Imperial nature of Russian subdivision of government changed towards a generally autonomous model which began with the establishment of the USSR (of which Russia was governed as part). It was liberalized in the aftermath of the Soviet Union, with the reforms under Boris Yeltsin preserving much of the Soviet structure while applying increasingly liberal reforms to the governance of the constituent republics and subjects (while also coming into conflict with Chechen secessionist rebels during the Chechen War). Some of the reforms under Yeltsin were scaled back by Vladimir Putin.
Who scaled back some reforms from Yeltsin? 
The answer is the following: Vladimir Putin

Problem: At the close of the 1991 season, a proposal was tabled for the establishment of a new league that would bring more money into the game overall. The Founder Members Agreement, signed on 17 July 1991 by the game's top-flight clubs, established the basic principles for setting up the FA Premier League. The newly formed top division would have commercial independence from The Football Association and the Football League, giving the FA Premier League licence to negotiate its own broadcast and sponsorship agreements. The argument given at the time was that the extra income would allow English clubs to compete with teams across Europe.
In 1991, was a proposal for a new league postponed?
The answer is the following:
At the close of the 1991 season, a proposal was tabled
