Answer:
The writer told the story.
Step-by-step explanation:
Hi there!
To change a sentence from passive voice to active voice, we must make the subject of the sentence the thing or person performing the action.
In this case, the action is telling the story, and the person/thing performing this action is the writer.
The story was told by the writer.
⇒ The writer told the story.
I hope this helps!
