Some copyright owners voluntarily reduce the scope of what is considered infringement by employing relatively permissive, "open" licensing strategies: rather than privately negotiating license terms with individual users who must first seek out the copyright owner and ask for permission, the copyright owner publishes and distributes the work with a prepared license that anyone can use, as long as they adhere to certain conditions. This has the effect of reducing infringement and the burden on courts by simply permitting certain types of uses under terms that the copyright owner considers reasonable. Examples include free software licenses, like the GNU General Public License (GPL), and the Creative Commons licenses, which are predominantly applied to visual and literary works.
What must a user do under a prepared license?
A: adhere to certain conditions

The BRA subsequently reevaluated its approach to urban renewal in its future projects, including the construction of Government Center. In 1965, the first Community Health Center in the United States opened, the Columbia Point Health Center, in the Dorchester neighborhood. It mostly served the massive Columbia Point public housing complex adjoining it, which was built in 1953. The health center is still in operation and was rededicated in 1990 as the Geiger-Gibson Community Health Center. The Columbia Point complex itself was redeveloped and revitalized into a mixed-income community called Harbor Point Apartments from 1984 to 1990. By the 1970s, the city's economy boomed after 30 years of economic downturn. A large number of high rises were constructed in the Financial District and in Boston's Back Bay during this time period. This boom continued into the mid-1980s and later began again. Hospitals such as Massachusetts General Hospital, Beth Israel Deaconess Medical Center, and Brigham and Women's Hospital lead the nation in medical innovation and patient care. Schools such as Boston College, Boston University, the Harvard Medical School, Northeastern University, Wentworth Institute of Technology, Berklee College of Music and Boston Conservatory attract students to the area. Nevertheless, the city experienced conflict starting in 1974 over desegregation busing, which resulted in unrest and violence around public schools throughout the mid-1970s.
In 1990, the Colombia Point Health Center was renamed what?
A: Geiger-Gibson Community Health Center

In each case, cables are attached to a hitch plate on top of the cab or may be "underslung" below a cab, and then looped over the drive sheave to a counterweight attached to the opposite end of the cables which reduces the amount of power needed to move the cab. The counterweight is located in the hoist-way and rides a separate railway system; as the car goes up, the counterweight goes down, and vice versa. This action is powered by the traction machine which is directed by the controller, typically a relay logic or computerized device that directs starting, acceleration, deceleration and stopping of the elevator cab. The weight of the counterweight is typically equal to the weight of the elevator cab plus 40-50% of the capacity of the elevator. The grooves in the drive sheave are specially designed to prevent the cables from slipping. "Traction" is provided to the ropes by the grip of the grooves in the sheave, thereby the name. As the ropes age and the traction grooves wear, some traction is lost and the ropes must be replaced and the sheave repaired or replaced. Sheave and rope wear may be significantly reduced by ensuring that all ropes have equal tension, thus sharing the load evenly. Rope tension equalization may be achieved using a rope tension gauge, and is a simple way to extend the lifetime of the sheaves and ropes.
What reduces the amount of force needed to propel the cab?
A: cables are attached to a hitch plate on top of the cab
