Select the pair which has the same relationship as the pair Birds: Wings.

Appeared in: RRB Staff Nurse Delhi-2015

Explanation

The fundamental relationship in 'Birds: Wings' is that of an entity and the specific part it uses for movement or locomotion.
A bird is an organism, and its wings are the appendages that enable it to fly.
Similarly, a car is a machine, and its wheels are the components that enable it to move on the ground.
Both pairs demonstrate a 'whole-to-part' relationship where the part's primary function is to facilitate the whole's movement.

Option A: This pair shows an 'Organism: Habitat' relationship. A whale lives in water, but water is not a part of the whale used for movement.
Option B: This pair shows an 'Organism: Organ' relationship, but the organ's function is respiration, not locomotion. Lungs are for breathing.
Option C: This pair shows a 'Tool: Surface' relationship. A pen is a tool used to act upon paper. This is a functional relationship, but not one of locomotion.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Analogical Reasoning as background academic context rather than a clinical decision trigger.
While this is not a clinical question, analogical reasoning is a critical skill for nurses.
Nurses use analogical reasoning to apply knowledge from one patient case to another, similar case, helping in quick decision-making and problem-solving.
For example, understanding how a medication works for one type of infection can help a nurse anticipate its effects on a similar type of infection.

How to Approach the Question

First, identify the precise relationship between the two words in the given pair (Birds: Wings). Here, the relationship is 'Entity: Part used for movement'.
Next, analyze each option to determine the relationship between its two words.
Eliminate the options where the relationship does not match the original pair's relationship.
Option A (Whale: Water) is Organism: Habitat.
Option B (Dog: Lungs) is Organism: Organ for a non-locomotor function.
Option C (Pen: Paper) is Tool: Surface.
