Article: Zhejiang benefited less from central government investment than some other provinces due to its lack of natural resources, a location vulnerable to potential flooding from the sea, and an economic base at the national average. Zhejiang, however, has been an epicenter of capitalist development in China, and has led the nation in the development of a market economy and private enterprises. Northeast Zhejiang, as part of the Yangtze Delta, is flat, more developed, and industrial.

Question: What type of development has Zhejiang been an epicenter of?
Ans: capitalist

Article: New York City is situated in the Northeastern United States, in southeastern New York State, approximately halfway between Washington, D.C. and Boston. The location at the mouth of the Hudson River, which feeds into a naturally sheltered harbor and then into the Atlantic Ocean, has helped the city grow in significance as a trading port. Most of New York City is built on the three islands of Long Island, Manhattan, and Staten Island.

Question: New York City is at the base of which American river?
Ans: Hudson

Article: Alleles at a locus may be dominant or recessive; dominant alleles give rise to their corresponding phenotypes when paired with any other allele for the same trait, whereas recessive alleles give rise to their corresponding phenotype only when paired with another copy of the same allele. For example, if the allele specifying tall stems in pea plants is dominant over the allele specifying short stems, then pea plants that inherit one tall allele from one parent and one short allele from the other parent will also have tall stems. Mendel's work demonstrated that alleles assort independently in the production of gametes, or germ cells, ensuring variation in the next generation. Although Mendelian inheritance remains a good model for many traits determined by single genes (including a number of well-known genetic disorders) it does not include the physical processes of DNA replication and cell division.

Question: Where can alleles be located in order to be either dominant or recessive?
Ans: at a locus

Article: In 1682, William Penn founded the city to serve as capital of the Pennsylvania Colony. Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 and the Constitution in 1787. Philadelphia was one of the nation's capitals in the Revolutionary War, and served as temporary U.S. capital while Washington, D.C., was under construction. In the 19th century, Philadelphia became a major industrial center and railroad hub that grew from an influx of European immigrants. It became a prime destination for African-Americans in the Great Migration and surpassed two million occupants by 1950.

Question: What purpose did Philadelphia serve while D.C. was under construction?
Ans:
temporary U.S. capital
