(4) Could you correct or confirm these questions?

Hi teachers,
This is for a listening comprehension exercise. The text is from a CD.
Alex Dinon has escaped from prison a day ago.

If this is what the students will hear:
Alex finished eating and drank some coffee. He began to feel better.
‘How did you escape from prison?’ Marta said suddenly.
Alex’s face went white. He stared at Marta and said nothing.
Marta laughed. ‘It’s all right,’ she said.

Are these suitable questions to ask?
1. When did he begin to feel better? After he ate and drank some coffee.
2. What did Marta ask quickly and unexpectedly? She asked, ‘How did you escape from prison?’
3. How did Alex’s face turn after her question? It turned white.
4. What did Alex do before Marta laughed? He stared at her and said nothing.

Thanks in advance.
