Classification – Tools and utilities: select the odd one out by primary function. Three items are tools with pointed working ends or tips; one is primarily a light source. Which option is different? Options: Needle, Pencil, Spade, Candle.

Introduction / Context:
Tool classification can rely on the nature of the working end and intended function. A needle, pencil, and spade have functional tips/edges for piercing, marking, or digging. A candle is not a tool for manipulating materials; it provides illumination.

Given Data / Assumptions:

• Needle: pointed tool for sewing.
• Pencil: pointed writing instrument.
• Spade: tool with a sharp edge for digging/cutting soil.
• Candle: light source; no pointed working end for material modification.

Concept / Approach:
Group by “implements with functional points/edges used on materials” vs “illumination object.”

Step-by-Step Solution:
Step 1: Note functional working ends of needle/pencil/spade.Step 2: Recognize candle has a wick and offers light, not a working tip for manipulation.Step 3: Therefore, Candle is the odd one out.

Verification / Alternative check:
Usage context confirms the split: three are tools; one is lighting/utility.

Why Other Options Are Wrong:
Needle/Pencil/Spade: All act on materials via a tip or edge.

Common Pitfalls:
Avoid superficial shape comparisons; prioritize function.

Final Answer:
Candle
