Final answer:
The imperative mood in English is used for giving commands or instructions, with verbs such as 'arrange', 'display', and 'restock', in which the subject 'you' is implied.
Step-by-step explanation:
In English grammar, the imperative mood is used to issue commands or instructions, an imperative verb directs the action towards the listener. In the provided scenarios by Nuan, since she is giving instructions for arranging objects in a shop, the verbs would be in the imperative mood, which might look something like:
Arrange the products in order of size.
Display the new items at the front.
Restock the shelves every morning.
In these instructions, the imperative verbs are 'arrange', 'display', and 'restock', respectively. Note that in imperative sentences the subject 'you' is often implied and is not explicitly stated. This mood contrasts with the indicative mood, which states facts or asks questions, and the subjunctive mood, which shows wishes, suggestions, or hypothetical situations.
