Hi teachers,
Alex looked quickly at the door, but he could not escape now. Then the shopkeeper called to him, ‘Hey, you!’ he said. ‘Quick! Go out through the back.’
Alex ran through the back of the shop, and the shopkeeper followed him.‘I never help the police –they’re all bad,’ he said.

1. Did Alex have the possibility to get away through the front door then? No, he didn’t.
2. Where could he escape through? Through the back door.
3. What did the shopkeeper at no time do? To help the police.

Thanks in advance.
