Question

Shown below is an animation of a bird flying. Which frame is NOT present in the animation? 

• A. A
• B. B
• C. C
• D. D

Hint:

For animations, focus on how the object or character moves between frames and ensure that each frame follows the natural motion.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
A flapping-wing animation moves the wing smoothly through a repeating cycle of angles, while the bird's eye, beak and body stay fixed from frame to frame.

Step 2: Key Formula or Approach:
Any genuine frame from the animation should show a wing angle that fits somewhere along that smooth cycle, with the same eye and beak as the main bird. A frame that changes the eye or body shape, not just the wing, does not belong.

Step 3: Detailed Explanation:
Options A, B and D all keep the same white-highlighted eye and yellow beak as the main bird, with only the wing angle changing between them, fitting smoothly into a flap cycle. Option C changes the eye to a plain solid dot and alters the wing and body shape as well, which is not something a consistent flap cycle would do.

Step 4: Final Answer:
Option C is the frame that does not belong to the animation.

Answer 2

Another way to check is to compare the overall silhouette of each small frame with the large bird shown on the left, since a genuine in-between frame should look like the same bird caught at a different moment, not a differently shaped bird.

1. Option A: The silhouette matches the main bird closely, just with the wing folded partway through the flap.
2. Option B: The silhouette again matches the main bird, with the wing at a slightly different point in the flap.
3. Option C: The silhouette is noticeably different from the main bird, the wing shape and the plain, highlight-free eye do not match the consistent look kept across the other frames.
4. Option D: The silhouette matches the main bird, with the wing captured at yet another valid point in the flap.

Comparing silhouettes confirms that option C is the odd one out, and therefore the frame that is not part of the animation.

So the correct answer is Option C.
