Classification (tool–result): Three pairs show a tool and the result it produces on a material; one pair does not match this relationship. Identify the odd pair.

Introduction / Context:Verbal classification frequently uses semantic relationships. Here, we compare pairs for a shared relation: a tool producing a characteristic result on a material. Three options fit; one breaks the pattern.

Given Data / Assumptions:

• Needle → Prick (effect on skin/fabric).
• Auger → Bore (effect: drill/make a hole in wood etc.).
• Chisel → Carve (effect: shape/cut a solid material like wood/stone).
• Gun → Fire (word “fire” here denotes an action, not a result produced on a material).

Concept / Approach:The shared relation is “tool produces a result on an external object/material.” We identify the pair deviating from this noun-result mapping.

Step-by-Step Solution:

Verification / Alternative check:Reword each as “Tool is used to …”: needle is used to prick; auger to bore; chisel to carve; gun to shoot, not to “fire” as a product/result noun.

Why Other Options Are Wrong:

Common Pitfalls:Equating “fire” with a persistent result rather than an action; the consistent form should be an effect noun like “hole” or “carving.”

Final Answer:Gun-Fire
