“Simon's attempts to find accommodation in Paris were not very successful. He tried (1-call) every hotel in his guidebook, but he was shocked to discover they were all full. He called all the youth hostels to find out if they had any beds, but they were full, too. Another traveler advised him to go to the tourist information office (2-ask) for help, but the office was closed. Although Simon hated the idea of (3-leave) Paris without having seen anything, the thought of sleeping in the train station or walking the streets all night convinced him to take the train to another city (4-look) for accommodation there.”
