Explanation:

Mr. Shriram, the manager, is explaining the operations of a hi-tech machine to a worker. This initial instruction phase falls under the communication aspect of direction, ensuring the worker understands the tasks and expectations.

However, the key element here is supervision. Explaining the operations beforehand suggests the worker might be new to the machine or the task requires specific expertise.

 Mr. Shriram's explanation, therefore, likely serves as preparatory guidance before overseeing the worker's actual operation of the machine. This active monitoring and oversight is the essence of supervision.

Therefore, while communication plays a role initially, the scenario emphasizes supervision as the essential element of directing in this case.
