Finding the Incompatible Word Pair

The question asks us to identify the word pair that does not fit the pattern or relationship shared by the other three pairs. We need to examine the relationship between the words in each pair.

Let's analyze each given word pair:

• Shoes - Leather: In this pair, Shoes are typically made from Leather. This represents a relationship where an object is made from a material.
• Duster - Chalk: A Duster is used to erase Chalk marks from a blackboard or surface. This pair shows a relationship of a tool and the substance it interacts with or cleans. It's a use-based relationship, not typically a material relationship like "made of".
• Shirt - Fabric: A Shirt is made from Fabric. This is another example of an object being made from a material.
• Glass - Glass: This pair can be interpreted as an object made of Glass (e.g., a drinking glass) is referred to as "Glass". This also represents an object-material relationship where the object is identified by its primary material.

Comparing the relationships:

• Shoes - Leather: Object made of Material
• Duster - Chalk: Tool used with Substance
• Shirt - Fabric: Object made of Material
• Glass - Glass: Object made of Material (named after material)

Three of the pairs (Shoes - Leather, Shirt - Fabric, Glass - Glass) show a relationship where the first word is an object primarily made from or associated with the material mentioned in the second word. The pair Duster - Chalk shows a different type of relationship, where one item (duster) is used to interact with or remove the other (chalk).

Therefore, the incompatible word pair is Duster - Chalk because its relationship (tool-substance interaction) is different from the material-object relationship seen in the other three pairs.
