12) Table 22-5
The citizens of Anytown will decide whether to build a new library, a recreation center,
or an arena. Exactly one of the three choices will prevail, and the choice will be made
by way of pairwise voting, with the majority determining the outcome on each vote.
The preferences of the voters are summarized in the table below.
Voter Type
Refer to Table 22-5. If (1) the first vote pits "library" against "arena," and (2) the second
vote pits "recreation center" against the winner of the first vote, then the outcome is as
follows:
a."Library" wins the first vote and "library" wins the second vote, so they build a
library.
b."Library" wins the first vote and "recreation center" wins the second vote, so they
build a recreation center.
c."arena" wins the first vote and "arena" wins the second vote, so they build an arena.
d."arena" wins the first vote and "recreation center" wins the second vote, so they build
a recreation center.
