Which of the following is an example of a hidden task

None of the options provided can be considered a hidden task. A hidden task refers to a task that is not explicitly assigned or apparent but is expected to be completed as part of someone's role or responsibilities. In the given options, all tasks mentioned are either explicit responsibilities or tasks that are expected as part of someone's role.

The example of a hidden task out of the options provided is:

"The office manager maintains an inventory of office supplies because he knows employees need them."

The example of a hidden task among the given options is "the office manager maintains an inventory of office supplies because he knows employees need them."

To identify the hidden task in this scenario, we need to understand what makes it hidden. A hidden task is a responsibility or duty that is not explicitly part of someone's role or job description but is necessary for the smooth operation of the organization.

In this case, it is not the office manager's primary role to maintain an inventory of office supplies. However, they take on this task because they understand that employees require these supplies to perform their work efficiently. Therefore, the office manager is handling a hidden task by maintaining the inventory of office supplies.

To find this answer, one can carefully analyze each scenario and determine if any of the tasks described are not explicitly part of the person's job but are necessary for the organization's functioning. In this case, by reviewing the scenarios, we can identify that the office manager's responsibility of maintaining an inventory of office supplies is an example of a hidden task.
