Problem: Question: "What should be used to study race?" Context: "Craig Venter and Francis Collins of the National Institute of Health jointly made the announcement of the mapping of the human genome in 2000. Upon examining the data from the genome mapping, Venter realized that although the genetic variation within the human species is on the order of 13% (instead of the previously assumed 1%), the types of variations do not support notion of genetically defined races. Venter said, "Race is a social concept. It's not a scientific one. There are no bright lines (that would stand out), if we could compare all the sequenced genomes of everyone on the planet." "When we try to apply science to try to sort out these social differences, it all falls apart."" Answer:

A: social concept

Problem: Question: "What is not boring?" Context: "QED vacuum has interesting and complex properties. In QED vacuum, the electric and magnetic fields have zero average values, but their variances are not zero. As a result, QED vacuum contains vacuum fluctuations (virtual particles that hop into and out of existence), and a finite energy called vacuum energy. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory. Some experimentally verified effects of vacuum fluctuations include spontaneous emission and the Lamb shift. Coulomb's law and the electric potential in vacuum near an electric charge are modified." Answer:

A: QED vacuum

Problem: Question: "What are waterfowl considered, traditionally?" Context: ""Poultry" is a term used for any kind of domesticated bird, captive-raised for its utility, and traditionally the word has been used to refer to wildfowl (Galliformes) and waterfowl (Anseriformes). "Poultry" can be defined as domestic fowls, including chickens, turkeys, geese and ducks, raised for the production of meat or eggs and the word is also used for the flesh of these birds used as food. The Encyclopdia Britannica lists the same bird groups but also includes guinea fowl and squabs (young pigeons). In R. D. Crawford's Poultry breeding and genetics, squabs are omitted but Japanese quail and common pheasant are added to the list, the latter frequently being bred in captivity and released into the wild. In his 1848 classic book on poultry, Ornamental and Domestic Poultry: Their History, and Management, Edmund Dixon included chapters on the peafowl, guinea fowl, mute swan, turkey, various types of geese, the muscovy duck, other ducks and all types of chickens including bantams. In colloquial speech, the term "fowl" is often used near-synonymously with "domesticated chicken" (Gallus gallus), or with "poultry" or even just "bird", and many languages do not distinguish between "poultry" and "fowl". Both words are also used for the flesh of these birds. Poultry can be distinguished from "game", defined as wild birds or mammals hunted for food or sport, a word also used to describe the flesh of these when eaten." Answer:

A: Poultry

Problem: Question: "What brought students to the area?" Context: "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." Answer:

A:
Schools
