Answer:
You'd like to call him, replied Paul.
"Mr. Paul Candor is the man who I'm looking for," said the man, with a suspicious tone of voice.
"Oh, yes, sir. That's me. You must be my tutor," said Paul, in a voice that didn't hide his skepticism.
"Yes, I'm Mr. Valentine, and I am definitely a verified tutor. Now let's get to work!" He said, hastily.
Paul welcomed Mr. Valentine into the house and they sat at the kitchen table and began to work.
Step-by-step explanation:
The story mentions Paul is suspicious about Mr.Valentine, so I rewrote the story as if Mr. Valentine is not fully equipped to tutor Paul. So here Mr. Valentine is nervous, but is trying not to show it. That would be a key character trait introducing Mr. Valentine into the story.
