Read the passage and answer the following questions:
Apart from the case in which culture and direct utility can be combined, there is the indirect utility of various kinds of knowledge which do not directly contribute to technical efficiency. I think some of the worst features of the modern world could be improved by a greater encouragement of such knowledge and less ruthless pursuit of more professional competence. When conscious activity is wholly concentrated on one definite purpose, the ultimate result, for most people this lack of balance is invariably accompanied by some form of the nervous disorder. The men who directed German policy during the war made mistakes, for example, as regards the submarine campaign which brought America on the side of the Allies, which any person coming fresh to the subject could have seen to be unwise, but which they could not judge sanely owing to mental concentration and lack of quality time spent on things like holidays. The same sort of thing may be seen wherever bodies of men attempt tasks which put a prolonged strain on their minds. Men, as well as children, have to need to play, that is to say, of periods of activity having no purpose. But if play has to serve its purpose, it must be possible to find pleasure and interest in matters not connected with work. Better economic organization allowing mankind to benefit by the productivity of machines should lead to a great increase of leisure, and much leisure is apt to be tedious except to those who have considerable intelligent activities and interest. If a leisured population is to be happy it must be an educated population and must be educated with a view to mental enjoyment as well as to the direct usefulness of technical knowledge.
