Article: The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design, because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper thought it was the most efficient design. Later, Otis designed a special elevator for the building. Today the Otis Elevator Company, now a subsidiary of United Technologies Corporation, is the world's largest manufacturer of vertical transport systems.

Question: What year did constructrion begin for the Cooper Union Foundation?
Ans: 1853

Article: Some 97 percent of male BYU graduates and 32 percent of female graduates took a hiatus from their undergraduate studies at one point to serve as LDS missionaries. In October 2012, the LDS Church announced at its general conference that young men could serve a mission after they turn 18 and have graduated from high school, rather than after age 19 under the old policy. Many young men would often attend a semester or two of higher education prior to beginning missionary service. This policy change will likely impact what has been the traditional incoming freshman class at BYU. Female students may now begin their missionary service anytime after turning 19, rather than age 21 under the previous policy. For males, a full-time mission is two years in length, and for females it lasts 18 months.

Question: What percentage of graduates had taken a hiatus from their BYU studies to serve as an LDS missionary?
Ans: 97

Article: Philadelphia has more public art than any other American city. In 1872, the Association for Public Art (formerly the Fairmount Park Art Association) was created, the first private association in the United States dedicated to integrating public art and urban planning. In 1959, lobbying by the Artists Equity Association helped create the Percent for Art ordinance, the first for a U.S. city. The program, which has funded more than 200 pieces of public art, is administered by the Philadelphia Office of Arts and Culture, the city's art agency.

Question: How many pieces of art were funded by the Percent for Art ordinance?
Ans: more than 200

Article: The emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the scholarly gentry class. The Han Empire was divided into areas directly controlled by the central government using an innovation inherited from the Qin known as commanderies, and a number of semi-autonomous kingdoms. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States. From the reign of Emperor Wu onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in AD 1911.

Question: What innovation was acquired from the Qin?
Ans:
commanderies
