What is the main idea about Karenin, the dog?

• A. He has a strong preference for predictability and dislikes disruption.
• B. He is indifferent to changes in his schedule.
• C. He is unaffected by changes in his environment.
• D. He measures time in minutes and seconds like humans.

Answer: (A)

Karenin’s behavior shows a clear pattern: he thrives on routine and becomes unsettled when things change. This highlights that he has a strong preference for predictability and dislikes disruption. The text conveys that even small shifts in schedule or surroundings can cause him discomfort, which is exactly what option in question describes. In other words, his need for a stable routine and his negative reaction to surprises best capture the main idea.

The other possibilities imply indifference, no impact from changes, or a human-like sense of time, none of which fit what the passage conveys about his reactions. Dogs naturally rely on routines to feel secure, so Karenin’s sensitivity to disruption fits that pattern.
