Problem: Pain:

Physical pain is an important political topic in relation to various issues, including pain management policy, drug control, animal rights or animal welfare, torture, and pain compliance. In various contexts, the deliberate infliction of pain in the form of corporal punishment is used as retribution for an offence, or for the purpose of disciplining or reforming a wrongdoer, or to deter attitudes or behaviour deemed unacceptable. In some cultures, extreme practices such as mortification of the flesh or painful rites of passage are highly regarded.

What kind of practices do some cultures highly regard?

A: extreme

Problem: Switzerland:

Swiss private-public managed road network is funded by road tolls and vehicle taxes. The Swiss autobahn/autoroute system requires the purchase of a vignette (toll sticker)which costs 40 Swiss francsfor one calendar year in order to use its roadways, for both passenger cars and trucks. The Swiss autobahn/autoroute network has a total length of 1,638 km (1,018 mi) (as of 2000) and has, by an area of 41,290 km2 (15,940 sq mi), also one of the highest motorway densities in the world. Zurich Airport is Switzerland's largest international flight gateway, which handled 22.8 million passengers in 2012. The other international airports are Geneva Airport (13.9 million passengers in 2012), EuroAirport Basel-Mulhouse-Freiburg which is located in France, Bern Airport, Lugano Airport, St. Gallen-Altenrhein Airport and Sion Airport. Swiss International Air Lines is the flag carrier of Switzerland. Its main hub is Zurich.

How many passengers used the Zurich airport in 2012?

A: 22.8 million

Problem: Incandescent light bulb:

In 1902, the Siemens company developed a tantalum lamp filament. These lamps were more efficient than even graphitized carbon filaments and could operate at higher temperatures. Since tantalum metal has a lower resistivity than carbon, the tantalum lamp filament was quite long and required multiple internal supports. The metal filament had the property of gradually shortening in use; the filaments were installed with large loops that tightened in use. This made lamps in use for several hundred hours quite fragile. Metal filaments had the property of breaking and re-welding, though this would usually decrease resistance and shorten the life of the filament. General Electric bought the rights to use tantalum filaments and produced them in the US until 1913.

What had a higher resistivity than carbon?

A: unanswerable

Problem: Detroit:

"Milliken was perhaps the greatest missed opportunity of that period," said Myron Orfield, professor of law at the University of Minnesota. "Had that gone the other way, it would have opened the door to fixing nearly all of Detroit's current problems." John Mogk, a professor of law and an expert in urban planning at Wayne State University in Detroit, says, "Everybody thinks that it was the riots [in 1967] that caused the white families to leave. Some people were leaving at that time but, really, it was after Milliken that you saw mass flight to the suburbs. If the case had gone the other way, it is likely that Detroit would not have experienced the steep decline in its tax base that has occurred since then."

At which school did Myron Orfield teach?
