Difficulty: Medium
Correct Answer: 5, 4, 2, 3, 1
Explanation:
Introduction / Context:
This logical sequence of words problem involves parts of the human upper limb. You must arrange Finger, Palm, Wrist, Elbow, and Shoulder in a meaningful sequence. The question does not explicitly state whether to move from body to extremity or from extremity to body, but in many reasoning questions of this type, the order from the tip of the limb towards the body is preferred, as it illustrates the path of movement or connection.
Given Data / Assumptions:
Concept / Approach:
To form the logical sequence, we recall the physical arrangement of these parts. At the outermost end are the Fingers, attached to the Palm. The Palm connects to the Wrist, which leads to the Forearm and Elbow. The upper arm then connects to the Shoulder near the body. Therefore, moving from the tip of the limb back towards the torso, the order is Finger, Palm, Wrist, Elbow, Shoulder. We then map these words to their given numbers and choose the option that matches this progression.
Step-by-Step Solution:
Step 1: Identify the outermost part: Finger is number 5.
Step 2: The Finger is connected to the Palm, which is number 4.
Step 3: The Palm leads to the Wrist, which is number 2.
Step 4: Moving further up the arm, the Wrist is followed by the Elbow, which is number 3.
Step 5: Finally, the Elbow is connected to the Shoulder, which is the part closest to the torso and is number 1.
Step 6: The correct anatomical sequence from extremity to body is therefore 5, 4, 2, 3, 1.
Verification / Alternative check:
We can visualise a simple diagram of the arm. Starting from the tip, we see Finger, then Palm, then Wrist, then Elbow, and finally Shoulder. This matches general anatomical knowledge and everyday experience. No other option captures this continuous path in the right order. For example, starting from the Shoulder and moving outwards would give 1, 3, 2, 4, 5, which is not among the answer choices. Therefore the only option that respects the true structure, 5, 4, 2, 3, 1, is correct.
Why Other Options Are Wrong:
Option A (2, 4, 5, 3, 1) begins with Wrist, then Palm, then Finger, which does not follow a clear directional progression from either end. Option B (3, 1, 4, 2, 5) places the Elbow before the Shoulder and mixes distal and proximal parts in an inconsistent way. Option C (3, 4, 5, 2, 1) begins at Elbow, jumps to Palm and Finger, and then moves back inland, which is not a natural linear path. These orders do not represent a smooth physical progression along the limb.
Common Pitfalls:
A frequent mistake is to assume that the sequence must always start from the body, ignoring the possibility of moving from extremity to body, or vice versa. Another pitfall is to think in terms of importance rather than actual physical arrangement. Visualising the arm and mentally tracing from the fingers to the shoulder (or the other way around) helps avoid such errors. Drawing a quick mental or rough sketch of the limb can also clarify the correct order.
Final Answer:
The meaningful sequence is 5, 4, 2, 3, 1, corresponding to Finger, Palm, Wrist, Elbow, Shoulder, which matches option D.
