Problem: Ann Arbor, Michigan:

A person from Ann Arbor is called an "Ann Arborite", and many long-time residents call themselves "townies". The city itself is often called "A²" ("A-squared") or "A2" ("A two") or "AA", "The Deuce" (mainly by Chicagoans), and "Tree Town". With tongue-in-cheek reference to the city's liberal political leanings, some occasionally refer to Ann Arbor as "The People's Republic of Ann Arbor" or "25 square miles surrounded by reality", the latter phrase being adapted from Wisconsin Governor Lee Dreyfus's description of Madison, Wisconsin. In A Prairie Home Companion broadcast from Ann Arbor, Garrison Keillor described Ann Arbor as "a city where people discuss socialism, but only in the fanciest restaurants." Ann Arbor sometimes appears on citation indexes as an author, instead of a location, often with the academic degree MI, a misunderstanding of the abbreviation for Michigan. Ann Arbor has become increasingly gentrified in recent years.

In recent years what has Ann Arbor become?

A: gentrified


Problem: Krugman's contention (that the growth of a commercial real estate bubble indicates that U.S. housing policy was not the cause of the crisis) is challenged by additional analysis. After researching the default of commercial loans during the financial crisis, Xudong An and Anthony B. Sanders reported (in December 2010): "We find limited evidence that substantial deterioration in CMBS [commercial mortgage-backed securities] loan underwriting occurred prior to the crisis." Other analysts support the contention that the crisis in commercial real estate and related lending took place after the crisis in residential real estate. Business journalist Kimberly Amadeo reports: "The first signs of decline in residential real estate occurred in 2006. Three years later, commercial real estate started feeling the effects. Denice A. Gierach, a real estate attorney and CPA, wrote:
According to most analysts, what crisis took place after the crisis in residential real estate?

Answer: the crisis in commercial real estate

Other main states with Venezuelan American populations are, according to the 1990 census, New York, California, Texas (adding their existing Hispanic populations), New Jersey, Massachusetts and Maryland. Some of the urban areas with a high Venezuelan community include Miami, New York City, Los Angeles, and Washington, D.C.
Are there any other areas of America Venezuelans settled in?

Question: The element was probably named by the alchemist Paracelsus after the German word Zinke (prong, tooth). German chemist Andreas Sigismund Marggraf is credited with discovering pure metallic zinc in 1746. Work by Luigi Galvani and Alessandro Volta uncovered the electrochemical properties of zinc by 1800. Corrosion-resistant zinc plating of iron (hot-dip galvanizing) is the major application for zinc. Other applications are in batteries, small non-structural castings, and alloys, such as brass. A variety of zinc compounds are commonly used, such as zinc carbonate and zinc gluconate (as dietary supplements), zinc chloride (in deodorants), zinc pyrithione (anti-dandruff shampoos), zinc sulfide (in luminescent paints), and zinc methyl or zinc diethyl in the organic laboratory.
Is there an answer to this question: What does the name zinc or zinke mean?

Answer: (prong, tooth)


Problem: PlayStation 3:

PS3's hardware has also been used to build supercomputers for high-performance computing. Fixstars Solutions sells a version of Yellow Dog Linux for PlayStation 3 (originally sold by Terra Soft Solutions). RapidMind produced a stream programming package for PS3, but were acquired by Intel in 2009. Also, on January 3, 2007, Dr. Frank Mueller, Associate Professor of Computer science at NCSU, clustered 8 PS3s. Mueller commented that the 256 MB of system RAM is a limitation for this particular application and is considering attempting to retrofit more RAM. Software includes: Fedora Core 5 Linux ppc64, MPICH2, OpenMP v 2.5, GNU Compiler Collection and CellSDK 1.1. As a more cost-effective alternative to conventional supercomputers, the U.S. military has purchased clusters of PS3 units for research purposes. Retail PS3 Slim units cannot be used for supercomputing, because PS3 Slim lacks the ability to boot into a third-party OS.

Who clustered 18 PS3s?
