question_answer 4)

 Why are most of the private hospitals and private schools located in major cities and not in towns or rural areas?  

Answer:

 People living in major cities can afford to send their children in private schools or get treatment in private hospitals.  In cities the people lead a busy life where they prefer to get their work done fast by taking appointments in spite of standing in long queues in government schools or hospitals.  Various facilities like transportation, electricity, water supply are easily available in major cities in comparison to towns or rural areas.
