Step-by-step explanation:
The student's question pertains to a scenario where a service call has been received, but the malfunction type is not known. Given it is 2:00 p.m., service technicians would likely need to triage the call by obtaining more information over the phone or scheduling a prompt visit to diagnose the issue. Effective service management is critical in addressing such scenarios in a business environment, especially in fields such as IT support, appliance repair, or any service-oriented industry that requires timely troubleshooting and solutions.
