Final answer:
The term 'retail' exemplifies a service, as it involves the activity of selling goods or services to consumers. Nonexcludable services, such as police protection or roads, are available to all without direct payment. Recreation and education and communication are sectors comprising both goods and services.
Step-by-step explanation:
Among the options provided for the question 'Which of the following exemplifies a service?', the correct answer is retail. Goods like candy, a laptop, a car, and laundry detergent are all tangible products. In contrast, retail specifically refers to the process or activity of selling goods or services to consumers. An example of a service within retail could be purchasing a used laptop at a garage sale, which involves the service of selling second-hand items. Another example is ordering flowers over the internet for a friend in a different city, where the service includes both the sale and delivery of the flowers.
Nonexcludable goods or services, such as police protection, roads, and primary education, are items or services that cannot be withheld from those who do not pay for them, and are accessible to all members of society. On the other hand, streaming music from satellite transmission programs and cell phone service are excludable since individuals must typically pay to access them.
Recreation and education and communication are also sectors within our economy, comprising items such as televisions, sports equipment, and services like college tuition and telephone services. These fall under the category of goods and services that people commonly purchase or use in their daily lives.
