The voters are divided into three groups based on their preferences.
Voter Type
Refer to Table 22-7. Which of the following statements is correct regarding the
Condorcet paradox and the results of pairwise voting on how to improve the safety of
the intersection?
a.The paradox implies that pairwise voting never produces transitive preferences, and
so the voting in the town fails to produce transitive preferences.
b.The paradox implies that pairwise voting sometimes (but not always) fails to produce
transitive preferences, but the voting in the town does produce transitive preferences.
c.The paradox implies that pairwise voting sometimes (but not always) fails to produce
transitive preferences, and the voting in the town fails to produce transitive preferences.
d.The paradox implies that pairwise voting always produces transitive preferences, and
so the voting in the town produces transitive preferences.

14) The market for diamond rings is closely linked to the market for high-quality
diamonds. If a large quantity of high- quality diamonds enters the market, then the
a.supply curve for diamond rings will shift right, which will create a shortage at the
