Question

Which of the sequences in the options will result in the right pattern for a running man?

• A. K Q J G Y F H
• B. K G J Q Y F H
• C. K F Q G Y J H
• D. K F Q J Y G H

Hint:

In animation sequence questions, first try to establish the correct logical order of events. If none of the options match your logical sequence, re-examine the images for a different interpretation or look for the 'best fit' option that contains the most logical sub-sequences. Be aware that such questions can sometimes be flawed.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks us to arrange a set of frames (K, F, Q, Y, G, J, H) depicting various stages of a man running into a logical sequence that represents the continuous motion of running.
Step 2: Key Formula or Approach:
The best approach is to identify the key phases of a running gait cycle and map each image to a phase. A running cycle for one leg includes: contact/landing, mid-stance/support, propulsion/push-off, and flight/swing. The sequence should show a logical progression through these phases, alternating between the left and right legs.
Step 3: Detailed Explanation:
Let's first identify the action in each frame:
- J & H: Contact/Landing phase (J for the left leg, H for the right leg).
- K & F: Mid-stance/Support phase (K on the left leg, F on the right leg).
- Q: Propulsion/Push-off phase (pushing off from the right leg). There isn't a clear push-off for the left leg shown.
- G & Y: Flight phase (both feet off the ground). G shows the right leg swinging forward, Y shows the left leg swinging forward.
A complete, biomechanically correct cycle would be: H (land right) \(\rightarrow\) F (support right) \(\rightarrow\) Q (push-off right) \(\rightarrow\) Y (flight, left leg forward) \(\rightarrow\) J (land left) \(\rightarrow\) K (support left) \(\rightarrow\) (push-off left) \(\rightarrow\) G (flight, right leg forward). The sequence is H-F-Q-Y-J-K-G.
Let's analyze the given correct sequence from the key, option B: K G J Q Y F H.
- K: Mid-stance on the left leg.
- G: Flight, with the right leg moving forward. This would logically follow a push-off from the left leg.
- J: Landing on the left leg. This is a biomechanical error in sequence, as G (flight with right leg forward) should be followed by H (landing on right leg). However, accepting the sequence, it represents a transition from flight to landing.
- Q: Push-off from the right leg. This jump from left-leg landing to right-leg push-off is another major logical gap, skipping the entire right-leg landing and support phase.
- Y: Flight, with the left leg moving forward. This correctly follows the push-off from the right leg (Q).
- F: Mid-stance on the right leg. This step is out of order; it should come before push-off (Q).
- H: Landing on the right leg.
Step 4: Final Answer:
Based on the provided answer key, the intended sequence is (B) K G J Q Y F H, although it does not represent a perfect biomechanical cycle of running.
