Consider a monopolistically competitive industry populated by n firms. Consumers have Constant Elasticity of Subsitution (C.E.S.) preferences over these goods. That is, their utility function takes the formU=(∑i=1nciε−1ε)εε−1, where the parameter ε, the elasticity of substitution between varieties, is strictly greater than 1 (i.e. ε>1). Which of the following statements is TRUE (there is ONLY ONE correct statement): Question 4Answer a. A higher ε results in a higher income elasticity of demand b. The higher ε is, the lower the mark-up above the marginal cost that firms can charge c. Each firm acts in a fully independent way of all the other firms in the industry because they are the sole monopolist producing a specific variety d. The higher ε is, the higher the mark-up above the marginal cost that firms can charge e. A higher ε results in firms' demand curves being more inelastic

2) Questions about standard ADT's and their implementations that we have studied, including asymptotic analysis of their operations under various implementations. A DougPriority Queue uses time (real numbers, not ints) for its priorities. The bigger the time of an item the more important it is. Describe a good time-efficient implementation of DougPriorityQueue. What is the bigO performance of your implementation for the 2 most important operations. Show a picture of your implementation when the following 4 items are in your DougPriority Queue: name=Bob,time=2.31 name=Jim,time=17.2 name=Bill, time=11.1 and name=Tom,time=22.
