Directions: Read the paragraph and answer the question that follows.

In descending the social scale in any modern industrial community, the primary fact -- the conspicuous leisure of the master of the household -disappears at a relatively high point. The head of the middle-class household has been reduced by economic circumstances to turn his hand to gaining a livelihood by occupations which often partake largely of the character of industry, as in the case of ordinary business man of today. But the derivative fact -- the vicarious leisure and consumption rendered by the wife, and the auxiliary vicarious performance of leisure by menials - remains in vogue as conventionality which the demands of reputability will not suffer to be slighted. It is by no means an uncommon spectacle to find a man applying himself to work with the utmost assiduity, in order that his wife may in due form render for him that degree of vicarious leisure which the common sense of the time demands.
