       1. A monopolistically competitive market is described as one in which there are 
       A) a few firms producing an identical product. 
       B) a large number of firms selling similar, but not identical, products.

       D) Firms sell similar, but not identical, products.  
        
        
       3. Because the monopolistically competitive firm faces a ________ demand curve for its 
       product, it ________ the price of its output. 
       A) downward-sloping; cannot influence 
       B) horizontal; can influence 
       C) horizontal; cannot influence 
       D) downward-sloping; can influence 
        
        
       4. A major difference between monopolistic competition and perfect competition is 
       A) the number of sellers in the markets. 
       B) the degree by which the market demand curves slope downwards. 
       C) that products are not standardized in monopolistic competition unlike in perfect competition. 
       D) the barriers to entry in the two markets. 
        
        
       5. For a monopolistically competitive firm, marginal revenue  
       A) always equals the price. 
       B) is greater than the price. 
       C) is less than the price. 
       D) and price are unrelated.
