Among Finch, Crow, Ostrich, Robin, which is different in a basic trait?

• A. Finch
• B. Ostrich
• C. Crow
• D. Robin

Answer: (B)

The main idea here is distinguishing animals by a fundamental lifestyle trait shared by many birds: flight capability. Finch, crow, and robin are all small to medium birds with wings and body plans geared for flying. They can take off, maneuver in the air, and travel long distances if needed. The ostrich, however, is a flightless bird. It has a heavy body, reduced wings, and leg and foot adaptations built for fast running on the ground, not for flight. This fundamental difference in flight ability makes it the one that stands out as different.
