What should be avoided in a class definition?

• A. Exclusionary phrases.
• B. Clear, concise statements.
• C. Quantitative thresholds.
• D. Consistent terminology.

Answer: (A)

Avoid exclusionary phrases because they narrow who belongs to a class and can introduce bias or ambiguity in who is included. When defining a class, use inclusive, positive criteria that clearly describe the group without excluding people by negation or by implicitly targeting a subset. This keeps the definition fair, understandable, and easier to apply consistently. For example, instead of saying a class is composed of “non-managers” or “those who are not veterans,” state the defining characteristics positively, such as “employees in the management track” or “employees with veteran status,” if those are the intended criteria. Positive, measurable criteria help ensure everyone who meets the stated attributes is included. The other aspects—clear, concise statements; quantitative thresholds when appropriate; and consistent terminology—are desirable features of any class definition. They support readability, objective assessment, and uniform understanding, whereas exclusionary wording undermines these goals.
