A restaurant features a lunch special with a choice of a wonton soup or spring roll to start (appetizer), chicken, pork, shrimp, or beef for the main dish and steamed or fried rice as a side dish. For desert, you may choose from an ice cream, a cookie, pie or cake. How many possible lunch specials are there at this restaurant if you cannot eat pork due to dietary restrictions and must have pie or cake for desert? Assume you may only choose one selection from the appetizer, main dish, side dish and desert. Clearly communicate your reasoning
