Context and question: At the end of the first decade of the 21st century, downtown Tucson underwent a revitalization effort by city planners and the business community. The primary project was Rio Nuevo, a large retail and community center that has been stalled in planning for more than ten years. Downtown is generally regarded as the area bordered by 17th Street to the south, I-10 to the west, and 6th Street to the north, and Toole Avenue and the Union Pacific (formerly Southern Pacific) railroad tracks, site of the historic train depot and "Locomotive #1673", built in 1900. Downtown is divided into the Presidio District, the Barrio Viejo, and the Congress Street Arts and Entertainment District. Some authorities include the 4th Avenue shopping district, which is set just northeast of the rest of downtown and connected by an underpass beneath the UPRR tracks.
When did a revitalization of downtown Tucson begin?
Answer: At the end of the first decade of the 21st century
Context and question: A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, Sybase, SAP HANA, and IBM DB2. A database is not generally portable across different DBMSs, but different DBMS can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database model that they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language.[disputed – discuss] Sometimes a DBMS is loosely referred to as a 'database'.
What is the purpose of a DBMS?
Answer: to allow the definition, creation, querying, update, and administration of databases
Context and question: There are at least two major approaches to understanding cognitive change during adolescence. One is the constructivist view of cognitive development. Based on the work of Piaget, it takes a quantitative, state-theory approach, hypothesizing that adolescents' cognitive improvement is relatively sudden and drastic. The second is the information-processing perspective, which derives from the study of artificial intelligence and attempts to explain cognitive development in terms of the growth of specific components of the thinking process.
The information-processing perspective towards cognitive development derives from the study of what?
Answer:
artificial intelligence
