Read the passage given below and answer the questions that follow.

Philosophers have often said that happiness, like beauty, is a byproduct, a lovely but accidental acquisition. As the bloom appears on flowers or on the face of youth, so does bliss slip into our lives. You set out to do something, you pin your mind to the purpose, you do the job, and lo! happiness descends upon you. But you must not think about the pleasure; stick to the deed, the action, and there comes the joy, a secret visitation. The nature of the deed does not matter greatly, so long as your heart and brain, and muscles are in the work. The way to ensure happiness is not to seek it. So they say, but mankind has never believed it. Mankind in the main is more concerned with pleasure than with happiness; it believes in a 'good time' which is made good by the very reason of our simple intention to enjoy. To be all out for fun is not nearly as foolish as the philosopher deems; holiday-makers often put up with crowding and fatigue and perhaps never get tired. But they know what they want and they achieve it.
