Understanding the Question: Correctly Matched Pairs

The question asks us to identify the pair from the given options where the item is correctly matched with its description or property.

Let's examine each option carefully to determine which pairing is accurate.

Analyzing Option 1: Coconut fiber – Waste material

Coconut fiber, also known as coir, is a natural fiber extracted from the husk of coconuts. While it might be considered a byproduct of coconut processing, it is not simply a waste material. It is a valuable resource used to make various products like doormats, brushes, ropes, netting, and even as a growing medium for plants. Therefore, matching coconut fiber solely with "waste material" is not entirely correct.

Analyzing Option 2: Knife – Easily available from nature

A knife is a tool, typically made from metal (like steel) and often with a handle made of wood, plastic, or other materials. While some components like wood might come from nature, a complete knife is a manufactured product. It is not something that is "easily available from nature" in its finished form. Early humans might have used sharp stones, but a modern knife is not a natural object.

Analyzing Option 3: Empty matchbox – Low cost material

An empty matchbox is usually made of cardboard, which is a paper-based material. Cardboard is generally considered a low-cost material, especially when used for simple items like matchboxes. However, the description "low cost material" might apply to many different things, and it's a relative term. Let's keep this in consideration as we look at the next option.

Analyzing Option 4: Soil – Easily available from nature

Soil is the loose surface layer of the Earth where plants grow. It is a natural resource that covers much of the planet's land surface. Soil is found almost everywhere outdoors and is readily accessible. Therefore, describing soil as something that is "easily available from nature" is accurate and fits well.

Conclusion: Identifying the Correct Match

Based on the analysis of each option:

• Coconut fiber is not just waste; it's a useful fiber.
• A knife is manufactured, not easily available from nature.
• An empty matchbox is made of low-cost material, but this might be true for many things.
• Soil is indeed easily available from nature.

Comparing the accuracy of the descriptions, the pairing of Soil – Easily available from nature is the most accurate and correctly matched statement among the given options.
