Arrange the following terms in order of increasing intension. A. Baseball…

Concept

The intension of a term is the set of attributes its meaning implies. A narrower class has greater intension because it carries more defining attributes, so increasing intension proceeds from the most general term to the most specific term.

Application

1. Athlete is the broadest term; it includes people in many sports.

2. Ball player adds the attribute of playing a game that uses a ball.

3. Baseball player adds the more specific attribute of playing baseball.

4. In the classification intended by this question, Fielder means a baseball player performing the fielding role.

Cross-check

Under the baseball-role convention used in this question, the extensions shrink in the reverse direction: a fielder is a baseball player, a baseball player is a ball player, and a ball player is an athlete. Thus the attributes increase at each step.

Therefore, the order of increasing intension is Athlete → Ball player → Baseball player → Fielder.
