The problem: Answer a question about this article:
Most elevators have a location in which the permit for the building owner to operate the elevator is displayed. While some jurisdictions require the permit to be displayed in the elevator cab, other jurisdictions allow for the operating permit to be kept on file elsewhere such as the maintenance office and to be made available for inspection on demand. In such cases instead of the permit being displayed in the elevator cab, often a notice is posted in its place informing riders of where the actual permits are kept.
What type of notice can be displayed in the elevator in lieu of the permit?
****
The answer: a notice is posted in its place informing riders of where the actual permits are kept.

The foundation of Northwestern University is traceable to a meeting on May 31, 1850 of nine prominent Chicago businessmen, Methodist leaders and attorneys who had formed the idea of establishing a university to serve what had once been known as the Northwest Territory. On January 28, 1851, the Illinois General Assembly granted a charter to the Trustees of the North-Western University, making it the first chartered university in Illinois. The school's nine founders, all of whom were Methodists (three of them ministers), knelt in prayer and worship before launching their first organizational meeting. Although they affiliated the university with the Methodist Episcopal Church, they were committed to non-sectarian admissions, believing that Northwestern should serve all people in the newly developing territory.
What was the religious affiliation of all 9 founding members of Northwestern?
****
The answer: Methodists

Between 1999 and 2006, Bicycling magazine named Boston three times as one of the worst cities in the US for cycling; regardless, it has one of the highest rates of bicycle commuting. In 2008, as a consequence of improvements made to bicycling conditions within the city, the same magazine put Boston on its "Five for the Future" list as a "Future Best City" for biking, and Boston's bicycle commuting percentage increased from 1% in 2000 to 2.1% in 2009. The bikeshare program called Hubway launched in late July 2011, logging more than 140,000 rides before the close of its first season. The neighboring municipalities of Cambridge, Somerville, and Brookline joined the Hubway program in summer 2012.
Bicycling magazine named Boston one of the worst cities in the US for what?

The answer: cycling

The problem: Answer a question about this article:
At a certain temperature, (usually between 1,500 F (820 C) and 1,600 F (870 C), depending on carbon content), the base metal of steel undergoes a change in the arrangement of the atoms in its crystal matrix, called allotropy. This allows the small carbon atoms to enter the interstices of the iron crystal, diffusing into the iron matrix. When this happens, the carbon atoms are said to be in solution, or mixed with the iron, forming a single, homogeneous, crystalline phase called austenite. If the steel is cooled slowly, the iron will gradually change into its low temperature allotrope. When this happens the carbon atoms will no longer be soluble with the iron, and will be forced to precipitate out of solution, nucleating into the spaces between the crystals. The steel then becomes heterogeneous, being formed of two phases; the carbon (carbide) phase cementite, and ferrite. This type of heat treatment produces steel that is rather soft and bendable. However, if the steel is cooled quickly the carbon atoms will not have time to precipitate. When rapidly cooled, a diffusionless (martensite) transformation occurs, in which the carbon atoms become trapped in solution. This causes the iron crystals to deform intrinsically when the crystal structure tries to change to its low temperature state, making it very hard and brittle.
Allotrophy happens between what temperatures?
****
The answer:
1,500 F (820 C) and 1,600 F (870 C)
