Which statement describes a temporary environment?

Which statement describes a temporary environment?

• A. Affects a single record.
• B. Affects the entire life.
• C. Affects the group.
• D. It is permanent.

Answer: (A)

A temporary environment is about short-lived influences that show up in one observation rather than lasting over time or affecting a whole group. The statement that best describes this is that it affects a single record. This makes sense because transient conditions during a specific measurement—like a momentary temperature, handling, or short-term stress—alter that particular observation but don’t persist across the animal’s life or across all records. In contrast, an effect that influences the entire life is a permanent environmental effect, an effect that influences the whole group is a shared or group effect, and describing it as permanent contradicts the idea of temporary.
