2. B

   Ostrich

3. C

   Pigeon

4. D

   Crow

Appeared in: DSSSB -28 August 2019 (Shift-2)

Explanation

• The core logic of this question is to find the outlier in a given set based on a common characteristic.
• The options Sparrow, Pigeon, and Crow are all common birds capable of flight.
• The Ostrich is the exception as it is a large, terrestrial bird that is incapable of flight.
• Therefore, the key differentiating factor is the ability to fly, making the Ostrich the correct answer.

Why Other Options Were Wrong

• Option A: A sparrow is a flying bird, which is a characteristic it shares with the pigeon and the crow. Therefore, it is not the unique option.
• Option C: A pigeon is a flying bird, similar to the sparrow and the crow. It does not stand out as different from the group.
• Option D: A crow is a flying bird, a trait it shares with the sparrow and the pigeon, making it part of the majority group in this context.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification and logical reasoning based on animal characteristics as background academic context rather than a clinical decision trigger.
• This type of question tests logical reasoning and classification skills, which are part of the General Intelligence section of many nursing entrance exams.
• While not directly clinical, the ability to categorize information, identify patterns, and spot anomalies is a foundational skill for nurses who must quickly assess patient symptoms and data to identify what is 'normal' versus what is a 'deviation' requiring intervention.
• What if the options were Penguin, Ostrich, Emu, and Kiwi? In that case, the Penguin would be the odd one out, as it is a flightless bird adapted for swimming, while the others are flightless birds adapted for running on land.

How to Approach the Question

• First, identify the category that all options belong to. In this case, all four are types of birds.
• Next, analyze the options to find a common characteristic shared by most, but not all, of them.
• Consider various attributes: size, color, habitat, diet, and physical abilities.
• Observe that Sparrow, Pigeon, and Crow are all common birds known for their ability to fly.
• Recognize that the Ostrich is distinct from this group because it is a flightless bird.
• Conclude that the characteristic of 'flight' is the differentiator, making Ostrich the option that is different from the rest.

Concept Tested & Keywords

• Concept Tested: Classification and logical reasoning based on animal characteristics.
• Stem keywords: Sparrow, Ostrich, Pigeon, Crow
• Lead-in keywords: different from the rest, NOT like the other three
• Negative lead-in flag: The question asks to identify the option that is NOT like the others.
