3 Page 3 of The basic questions of what to produce and for whom to produce are essentially interdependent because a. a particular level of output may be produced by many different combinations of inputs. b. different patterns of factor use generate different patterns of income distribution. c. income and wealth are concentrated in the hands of the economically powerful. d. markets cannot be relied upon to allocate resources efficiently. e. different patterns of distribution generate different patterns of demand and therefore different patterns of resource allocation. 1.6 If the production possibility boundary for a two-good economy is a negatively sloped straight line, one can conclude that a. opportunity costs are increasing as production of one good rises. b. opportunity costs are falling as production of one good rises. c. an increase in the production of one good will involve no sacrifice of the other good. d. resources are able to produce either product equally well. e. resources are not perfect substitutes in alternative uses. 1.7 Consider a production possibility frontier showing maximum combinations of guns and roses that could be produced from a given set of resources.
