Problem: The output of goods and services produced by labor and property located in the United Statesdecreased at an annual rate of approximately 6% in the fourth quarter of 2008 and first quarter of 2009, versus activity in the year-ago periods. The U.S. unemployment rate increased to 10.1% by October 2009, the highest rate since 1983 and roughly twice the pre-crisis rate. The average hours per work week declined to 33, the lowest level since the government began collecting the data in 1964. With the decline of gross domestic product came the decline in innovation. With fewer resources to risk in creative destruction, the number of patent applications flat-lined. Compared to the previous 5 years of exponential increases in patent application, this stagnation correlates to the similar drop in GDP during the same time period.
The U.E. employment rate was 10.2% in October 2009, which was the highest rate since what year?
The answer is the following: 1983

Problem: The word asphalt is derived from the late Middle English, in turn from French asphalte, based on Late Latin asphalton, asphaltum, which is the latinisation of the Greek (asphaltos, asphalton), a word meaning "asphalt/bitumen/pitch", which perhaps derives from -, "without" and (sfallo), "make fall". Note that in French, the term asphalte is used for naturally occurring bitumen-soaked limestone deposits, and for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads. It is a significant fact that the first use of asphalt by the ancients was in the nature of a cement for securing or joining together various objects, and it thus seems likely that the name itself was expressive of this application. Specifically Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From the Greek, the word passed into late Latin, and thence into French (asphalte) and English ("asphaltum" and "asphalt").
What are the meanings of the Greek word for asphalt?
The answer is the following: asphalt/bitumen/pitch

Problem: South Tucson is actually the name of an independent, incorporated town of 1 sq mi (2.6 km2), completely surrounded by the city of Tucson, sitting just south of downtown. South Tucson has a colorful, dynamic history. It was first incorporated in 1936, and later reincorporated in 1940. The population consists of about 83% Mexican-American and 10% Native American residents. South Tucson is widely known for its many Mexican restaurants and the architectural styles which include bright outdoor murals, many of which have been painted over due to city policy.
How large is South Tucson?
The answer is the following: 1 sq mi (2.6 km2)

Problem: The main cause of TB is Mycobacterium tuberculosis, a small, aerobic, nonmotile bacillus. The high lipid content of this pathogen accounts for many of its unique clinical characteristics. It divides every 16 to 20 hours, which is an extremely slow rate compared with other bacteria, which usually divide in less than an hour. Mycobacteria have an outer membrane lipid bilayer. If a Gram stain is performed, MTB either stains very weakly "Gram-positive" or does not retain dye as a result of the high lipid and mycolic acid content of its cell wall. MTB can withstand weak disinfectants and survive in a dry state for weeks. In nature, the bacterium can grow only within the cells of a host organism, but M. tuberculosis can be cultured in the laboratory.
In nature, what "helper" does the MTB bacterium require to grow?
The answer is the following:
a host organism
