Answer the question based on the following passage.

            Thinking about work is the beginning of one of the happiest
            and most useful of our experiences. Through work comes to
            us the pleasure of a growing knowledge of the great world
            and its wonders, the delight of intercourse with other people,
(5)        and the happiness of friendship with our fellow-workers. Work
            well done is a doorway to whatever good things we most desire.
            Best of all, perhaps, to the girl who is earning her living, is the
            satisfaction of feeling that she is a useful citizen.
            Girls today have a wide field from which to choose their
(10)      particular form of occupation. To choose wisely is a duty we
            owe to ourselves and to our country — to ourselves, because
            a wise choice helps to secure our happiness in work; to our
            country, because she has a right to the best we can offer her
            in return for the peace and freedom in which we live under
(15)      her laws.
            Every year work at home is being systematized, and new
            devices are increasing the efficiency of the work of a home.
            Among the girls who are beginning work to-day are some
            who will develop further the management of the home on
(20)      modern economic and social lines. Forward-thinking people
            anticipate a great advance which will be made by the girls
            of the twenty-first century in the management of homes.
            The most important fact for the girl to learn about employment
            is that when she does well-chosen work in the right spirit, she
(25)      will find in it happiness and usefulness. Through her work she
            will learn what an interesting place the world is.
