Answer:
Did you walk the dog today? -- interrogative
Walk the dog before dinner. -- imperative
I took the dog for a half-mile walk. -- indicative
Step-by-step explanation:
The interrogative mood is when the verb is used to ask questions. For example: Were you cooking when I called?
In the imperative mood, a verb expresses a command, a request, or even a suggestion in a more direct way. For example: Don't forget to clean your room.
The indicative mood is used to state facts, at least from the perspective of the one who is speaking. For example: Jane didn't talk to me yesterday.
