Would you correct the following one?

Hi teachers,
Context:
‘Oh, I know that,’ Marta said. The newspapers said that. But newspapers and the television never tell us the true story. Alex Dinon isn’t a murderer. He’s a nice young man.’
‘A nice young man?’ Felix said quickly. ‘How do you know that?’
‘He’s got a nice face. That’s why. I saw his picture on the television. I’m an old woman and I can read people’s faces.’

Would the following be a suitable question and answer?
Why did Marta know he was a nice young man?
Because she saw his face on TV and she could read people's faces.

Thanks in advance.
