A cinema hall installs a self-service ticket machine along with the ticket counter. This is an example of what?

Correct answer: Self-service technology

The direct answer is option B, self-service technology. A self-service ticket machine allows a customer to choose a service and complete a transaction using a machine, often without direct help from an employee. The cinema has not merely added another counter; it has introduced a technology-based service method. Option A, religious belief, concerns faith and worship, which has no connection with ticket machines. Option B is correct because the customer serves themselves through the machine. Option C, foreign trade, concerns buying and selling goods or services across national borders; no international exchange is mentioned. Option D, political party, concerns an organisation involved in politics; it is completely unrelated. The machine is also a clear example of technological change in the business environment because it uses automation to improve service and reduce waiting. Memory cue: when the customer operates the machine directly, think self-service technology.
