Final answer:
In a transcript, Sally's 5-second pause while talking about making a sandwich would be noted as [pause 5 seconds].
Step-by-step explanation:
When transcribing an event such as Sally pausing for 5 seconds while describing how to make a sandwich, it is common practice to denote pauses and other non-verbal actions within a transcript using notations. The pause would typically be represented with a notation such as [pause 5 seconds] or something similar, to indicate the duration of the silence. This helps to convey not only the spoken words but also the pacing and flow of the conversation, which can be important to the overall context.
