Association football is the country's most popular and most televised franchised sport. Its important venues in Mexico City include the Azteca Stadium, home to the Mexico national football team and giants America, which can seat 91,653 fans, making it the biggest stadium in Latin America. The Olympic Stadium in Ciudad Universitaria is home to the football club giants Universidad Nacional, with a seating capacity of over 52,000. The Estadio Azul, which seats 33,042 fans, is near the World Trade Center Mexico City in the Nochebuena neighborhood, and is home to the giants Cruz Azul. The three teams are based in Mexico City and play in the First Division; they are also part, with Guadalajara-based giants Club Deportivo Guadalajara, of Mexico's traditional "Big Four" (though recent years have tended to erode the teams' leading status at least in standings).

However, performance enhancements cannot be generalized as the benefits and limitations of the system are dependent on many factors. One problem is that the system is subject to gaming. Sometimes, one person enters the destination for a large group of people going to the same floor. The dispatching algorithm is usually unable to completely cater for the variation, and latecomers may find the elevator they are assigned to is already full. Also, occasionally, one person may press the floor multiple times. This is common with up/down buttons when people believe this to be an effective way to hurry elevators. However, this will make the computer think multiple people are waiting and will allocate empty cars to serve this one person.
What is one example of a limitation on the system?
****
The answer: the system is subject to gaming

The 1916 Zoning Resolution required setbacks in new buildings, and restricted towers to a percentage of the lot size, to allow sunlight to reach the streets below. The Art Deco style of the Chrysler Building (1930) and Empire State Building (1931), with their tapered tops and steel spires, reflected the zoning requirements. The buildings have distinctive ornamentation, such as the eagles at the corners of the 61st floor on the Chrysler Building, and are considered some of the finest examples of the Art Deco style. A highly influential example of the international style in the United States is the Seagram Building (1957), distinctive for its facade using visible bronze-toned I-beams to evoke the building's structure. The Conde Nast Building (2000) is a prominent example of green design in American skyscrapers and has received an award from the American Institute of Architects as well as AIA New York State for its design.
What building known for its bronze-tinted I-beams was completed in 1957?
****
The answer:
Seagram Building
