4. b. The woman’s response indicates that the man can contact Gabriel through his cell phone, so it islogical to assume that that is what the man will do. There is no indication that the man will go pur-chase a cell phone (choice a). The man’s concern is that he will keep Gabriel waiting because he mustmeet with his professor, so it is not logical to assume that he will either postpone his meeting with hisprofessor (choice c) or call his professor on the cell phone (choice d)—besides, there is no indicationfrom the conversation that he has his professor’s cell phone number (or that his professor even has acell phone).
