Answer 2

Answer:

I finished my work just now.

Explanation:

In the sentence,

I finished my work just now.

we use the word finished because the action or work is completed. The verb used is in the simple past tense.

We use simple past tense when an action has been done in the past. For example-

1. I went for a walk.
2. I ate a sandwich for lunch.

All the verbs are in the simple past tense as the actions were completed.
