E) none of the above 47) Indifference curves are convex to the origin because of: A) transitivity of consumer preferences. B) the assumption of a diminishing marginal rate of substitution. C) the assumption that more is preferred to less. D) the assumption of completeness. E) none of the above Clothing (units per work) Food (units per week) Figure 3.1.3 48) Refer to Figure 3.1.3 above. The way in which the indifference curves are drawn in this figure: A) represents a unique case in which two different indifference curves offer the same level of utility. B) compares three market baskets that yield the same level of utility. C) violates the principle of transitivity in the model of consumer behavior. D) represents the usual way in which indifference curves appear on an indifference map
