I believe that the question wants you to put it into chronological order. This is how I would do it step by step.
If you need a doctor for your child in a strange town, find the name of the best hospital. Next, telephone and ask for the name of a pediatrician on the staff. He will give you the name of one or two suitable doctors. Should there be any hitch, ask to speak to the physician-in-chief. Finally, the physician-in-chief Will in all probability be a children’s specialist.
Hope this helps!
