in a 5-option mbc, by contrast, votes for only 1 option thus gives the favorite just 1 point; votes for 2 options give first preference 2 points (and second preference 1 point). to ensure the favorite gets the maximum 5 points, therefore, all 5 preferences should be cast. the mbc thus encourages voters to submit a fully marked ballot at the expense of giving candidates other than a favorite a higher rankings, increasing their chances to win as well.
