Final answer:
Doctors, locksmiths, plumbers, and lawn care specialists are examples of independent contractors. They provide a mix of mental and physical labor and are paid per job, contrasting with salaried employees. Option B is correct.
Step-by-step explanation:
Doctors, locksmiths, plumbers, and lawn care specialists are likely examples of independent contractors. These professionals often operate their own businesses or offer their services to clients on an independent basis, which contrasts with salaried employees who typically work for one employer on a long-term basis.
Independent contractors are usually hired to perform a specific job or service and are paid per job or on a freelance basis, rather than receiving a regular salary or hourly wages.
Labor performed by contractors can be both mental, such as organizing blueprints and adhering to building code regulations, and physical, such as the construction of projects. Certain types of employment and unemployment are categorized differently based on their causes and conditions.
For instance, cyclical unemployment might include landscapers laid off during a recession due to a drop in new housing construction, while structural unemployment could include coal miners laid off due to new EPA regulations.
