Final answer:
The efficiency of a service can be influenced by the balance of variable and fixed components, with variable components allowing for easier adjustment to demand. However, efficiency is also dependent on how resources are managed and other business factors.
Step-by-step explanation:
The statement that a service with more variable components (compared to the fixed components) is more efficient can be true or false depending on the context. In business, having variable inputs means that a service can adjust more easily to demand fluctuations. For instance, a pizzaiolo can order more ingredients, which are variable inputs, with a simple phone call. However, this doesn't always translate to efficiency, as the quality of the service, management of resources, and other factors also play a crucial role. Efficiency in this context refers to the optimal use of resources to achieve the desired outcome.
