I ' ve only spoken to him two or three times since he left , so either he 's having a great time or they wo n't let him use the phone in the Mexican prison .

Question: What may be the reason they wo nt let him use the phone ?
Answer: The police may be using a phone that is painted on the wall and not real .The police may need quarters to put in the slot before they can call .None of the above choices .The police may not be able to afford a phone because they are so poor .
