Questions: One hundred riders from several countries participated in a bicycle race. Only eighty riders, including Carlos and Manuel, finished the race. Carlos finished 5th and Manuel was the winner. All the riders' countries of origin and finishing times were recorded on the race register. No two riders who finished had the same time and those who did not finish were recorded as DNF. Based on this information, determine if each set is well-defined. Set Is the set well-defined? ------ The set of riders with the best looking uniforms Yes No The set of countries of origin of the first ten riders to finish 0 The set of riders who finished 10 minutes or less after the winner 0 The set of the three most tired riders at the end 0 0 The set of riders who started but did not finish the race 0 0

The set defined by ^aesthetic judgments^ is ^No^ well-defined.
