Understanding Analogies: Pen and Brush Relationship

This question asks us to find a relationship between two items and then apply that same relationship to a different pair of items. This is known as solving an analogy problem.

The first pair given is 'Pen' and 'Ink'. We need to figure out how a pen is related to ink. A pen is a tool that uses ink to write or draw on a surface like paper. So, the relationship is that the first item (Pen) is a tool that uses the second item (Ink) as its primary medium or consumable material to perform its function.

Now, we apply this same relationship to the second pair: 'Brush' and '__________'. A brush is a tool used for applying a medium to a surface. We need to find what medium a brush typically uses from the given options.

Analyzing the Options for the Brush Analogy

• Option 1: Pencil
  A pencil is a different tool altogether. A pencil uses graphite (often called 'lead') as its marking medium, not something applied by a brush. So, 'Brush' is not related to 'Pencil' in the same way 'Pen' is related to 'Ink'.
• Option 2: Paint
  A brush is commonly used to apply paint to a surface. Paint is the medium that a brush uses to perform its function of colouring or decorating. This relationship matches the Pen : Ink relationship. The brush is the tool, and paint is the material it uses.
• Option 3: Paper
  Paper is the surface on which one might use a pen, ink, brush, or paint. It is not the material that the brush itself uses to function. So, this option does not fit the analogy.
• Option 4: Drawing Book
  A drawing book is similar to paper – it's a surface or collection of surfaces for drawing or painting. It is not the medium that a brush uses. So, this option does not fit the analogy either.

Based on the analysis, the item that a 'Brush' uses as its primary medium, just as a 'Pen' uses 'Ink', is 'Paint'.

Additional Information: Exploring Analogies and Tools

Analogies help us understand relationships between different things. In reasoning questions, common analogy types include:

• Tool and Action: e.g., Knife : Cut (Knife is a tool used for cutting).
• Tool and Object Used: e.g., Hammer : Nail (Hammer is used with a nail).
• Tool and Medium: e.g., Pen : Ink, Brush : Paint (Tool uses this substance).
• Part and Whole: e.g., Finger : Hand (Finger is a part of a hand).
• Cause and Effect: e.g., Fire : Ash (Fire causes ash).
• Worker and Tool: e.g., Carpenter : Saw (Carpenter uses a saw).

Identifying the exact relationship in the first pair is crucial to correctly solving the analogy for the second pair. In this case, understanding the 'tool uses medium' relationship for Pen and Ink directly leads to finding the correct pair for Brush.
