Answer: D
Answer to Question 2
Answer: A service is any activity that fulfills a human want or need and returns money to those who provide it. Services generate less than half of GDP in developing countries, compared to two-thirds in the developed world. The service sector of the economy is subdivided into three types, consumer services, business services, and public services. Each of these sectors is divided into several major subsectors.
Consumer services provide services to individual consumers who desire them and can afford to pay for them. Nearly half of all jobs in the United States are in consumer services. The four main types of consumer services are retail, education, health, and leisure.
Business services facilitate other businesses. A fourth of all jobs in the United States are in business services. Professional services, financial services, and transportation services are the three main types of business services.
Public services provide security and protection for citizens and businesses. About 16 percent of all U.S. jobs are in the public sector, 9 percent if public school employees were excluded from the total and counted instead under education (consumer) services. Excluding educators, one-sixth of public-sector employees work for the Federal Government, one-fourth for one of the 50 state governments, and three-fifths for one of the tens of thousands of local governments. When educators are counted, the percentages for state and local governments would be higher.
