8) Scenario 22-4
Three members of the DiCarlo family, Vinny, Maria, and Franki, are choosing the
entree for a large family reunion. Their options are: spaghetti, ravioli, lasagne, and

Refer to Scenario 22-4. Maria recommends using a vote by majority rule and proposes
first choosing between spaghetti and lasagne, then choosing between the winner of the
first vote and ravioli, and finally choosing between the winner of the second vote and
pizza. If everyone votes according to his or her preferences,
a.the winner of the first vote will be spaghetti, the winner of the second vote will be
ravioli, and the winner of the final vote will be ravioli.
b.the winner of the first vote will be spaghetti, the winner of the second vote will be
spaghetti, and the winner of the final vote will be spaghetti.
