Problem: Between the 199293 season and the 201213 season, Premier League clubs had won the UEFA Champions League four times (as well as supplying five of the runners-up), behind Spain's La Liga with six wins, and Italy's Serie A with five wins, and ahead of, among others, Germany's Bundesliga with three wins (see table here). The FIFA Club World Cup (or the FIFA Club World Championship, as it was originally called) has been won by Premier league clubs once (Manchester United in 2008), and they have also been runners-up twice, behind Brazil's Brasileirao with four wins, and Spain's La Liga and Italy's Serie A with two wins each (see table here).
How many times has the Premier League won the World Cup (FIFA Club) during that same time period?
The answer is the following: won by Premier league clubs once (Manchester United in 2008)

Problem: Others have pointed out that there were not enough of these loans made to cause a crisis of this magnitude. In an article in Portfolio Magazine, Michael Lewis spoke with one trader who noted that "There weren't enough Americans with [bad] credit taking out [bad loans] to satisfy investors' appetite for the end product." Essentially, investment banks and hedge funds used financial innovation to enable large wagers to be made, far beyond the actual value of the underlying mortgage loans, using derivatives called credit default swaps, collateralized debt obligations and synthetic CDOs.
Credit default swaps, collateralized debt obligations and CDOS are all types of what?
The answer is the following: derivatives

Problem: Alloys are often made to alter the mechanical properties of the base metal, to induce hardness, toughness, ductility, or other desired properties. Most metals and alloys can be work hardened by creating defects in their crystal structure. These defects are created during plastic deformation, such as hammering or bending, and are permanent unless the metal is recrystallized. However, some alloys can also have their properties altered by heat treatment. Nearly all metals can be softened by annealing, which recrystallizes the alloy and repairs the defects, but not as many can be hardened by controlled heating and cooling. Many alloys of aluminium, copper, magnesium, titanium, and nickel can be strengthened to some degree by some method of heat treatment, but few respond to this to the same degree that steel does.
Softening metals can be achieved by?
The answer is the following: annealing

Problem: Mosaic art also flourished in Christian Petra where three Byzantine churches were discovered. The most important one was uncovered in 1990. It is known that the walls were also covered with golden glass mosaics but only the floor panels survived as usual. The mosaic of the seasons in the southern aisle is from this first building period from the middle of the 5th century. In the first half of the 6th century the mosaics of the northern aisle and the eastern end of the southern aisle were installed. They depict native as well as exotic or mythological animals, and personifications of the Seasons, Ocean, Earth and Wisdom.
The scenes depicted on the mosaics were both native and what kind of mythological animals?
The answer is the following:
exotic
