Identify the odd word out?

Appeared in: Bihar CHO - 2021

Explanation

'Wall' because it is a finished structure.
Brick, Sand, and Cement are all raw materials used in the process of construction.
The relationship is between raw materials and the final product.
Wall is the result of combining the other three items, making it the odd one out in this group.

Option A: Brick is a raw material used for construction, similar to sand and cement.
Option B: Sand is a fundamental component used in making mortar and concrete, placing it in the same category as brick and cement.
Option C: Cement acts as a binder for bricks and sand, making it another essential raw material for construction.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Classification as background academic context rather than a clinical decision trigger.
This type of question tests logical reasoning and the ability to categorize information, which are foundational skills for nurses.
Nurses use classification skills to group patient symptoms, assess priorities, and differentiate between various conditions or medication types.
What if the options were 'Foundation', 'Pillar', 'Roof', and 'Cement'? In that case, 'Cement' would be the odd one out, as the others are all structural parts of a building, while cement is the material used to build them.

How to Approach the Question

First, read all the options to understand the words provided: Brick, Sand, Cement, Wall.
Next, try to find a common characteristic or relationship that links most of the words together.
Observe that Brick, Sand, and Cement are all materials used in construction.
Then, analyze the remaining word, 'Wall', to see if it fits the same category.
Recognize that a 'Wall' is not a material but a structure built using those materials.
Conclude that 'Wall' is the 'odd one out' because it represents the finished product, while the others are raw materials.
