30. We say that an end pursued in its own right is more complete than an end pursued because of something else, and that an end that is never choiceworthy because of something else is more complete than ends that are choiceworthy both in their own right and because of this end. Hence, an end that
29. Th ough it is possible that REM sleep and dreaming are not necessary in the adult, REM deprivation studies seem to suggest otherwise. Why would REM pressure increase with deprivation if the system is unimportant in the adult?Each of the following passages contains a single argument. Using the

20. Corn is an annual crop. Butcher’s meat, a crop which requires four or fi ve years to grow. As an acre of land, therefore, will produce a much smaller quantity of the one species of food than the other, the inferiority of the quantity must be compensated by the superiority of the price.Each of
★19. Poverty off ers numerous benefi ts to the nonpoor. Antipoverty programs provide jobs for middle-class professionals in social work, penology, and public health. Such workers’ future advancement is tied to the continued growth of bureaucracies dependent on the existence of poverty. Each of
