Problem: Cardinal (Catholicism):

Cardinal bishops (cardinals of the episcopal order) are among the most senior prelates of the Catholic Church. Though in modern times most cardinals are also bishops, the term "cardinal bishop" only refers to the cardinals who are titular bishops of one of the "suburbicarian" sees.

Who is among the most junior prelates of the Catholic Church?

A: unanswerable


Problem: Han dynasty:

Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722–481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.

What type of iron could pig iron be converted into?
---
A: wrought


Problem: Transistor:

Because the electron mobility is higher than the hole mobility for all semiconductor materials, a given bipolar n–p–n transistor tends to be swifter than an equivalent p–n–p transistor. GaAs has the highest electron mobility of the three semiconductors. It is for this reason that GaAs is used in high-frequency applications. A relatively recent FET development, the high-electron-mobility transistor (HEMT), has a heterostructure (junction between different semiconductor materials) of aluminium gallium arsenide (AlGaAs)-gallium arsenide (GaAs) which has twice the electron mobility of a GaAs-metal barrier junction. Because of their high speed and low noise, HEMTs are used in satellite receivers working at frequencies around 12 GHz. HEMTs based on gallium nitride and aluminium gallium nitride (AlGaN/GaN HEMTs) provide a still higher electron mobility and are being developed for various applications.

Which material has the highest electron mobility?
---
A: unanswerable


Problem: Oklahoma City:

After a lackluster arrival to Oklahoma City for the 2008–09 season, the Oklahoma City Thunder secured a berth (8th) in the 2010 NBA Playoffs the next year after boasting its first 50-win season, winning two games in the first round against the Los Angeles Lakers. In 2012, Oklahoma City made it to the NBA Finals, but lost to the Miami Heat in five games. In 2013 the Thunder reached the Western Conference semifinals without All-Star guard Russell Westbrook, who was injured in their first round series against the Houston Rockets, only to lose to the Memphis Grizzlies. In 2014 Oklahoma City again reached the NBA's Western Conference Finals but eventually lost to the San Antonio Spurs in six games.

What place were the Thunder in 2010 NBA playoffs?
---
A:
8th
