  4. D.I and III
  5. E.I, II, III and IV

Answer: C. I and II

Explanation written with AI and checked against the answer key

Analyze the question: We are asked which of the listed natural resources are renewable, meaning resources that can be replaced or regenerated naturally within a reasonable (human) time span.

Concept:

  • Renewable resources can reproduce or regenerate themselves. Examples are wildlife, forests, water, and solar energy.
  • Non-renewable resources are formed over millions of years and cannot be replaced within human timescales once used up. Examples are fossil fuels (coal, petroleum, natural gas) and minerals (iron ore, tin, limestone).

Step-by-step solution:

| Resource | Type | Reason | |---|---|---| | I. Wildlife | Renewable | Animals reproduce and replenish their populations (if properly conserved) | | II. Forest | Renewable | Trees can regrow or be replanted (e.g. afforestation) | | III. Fossil fuel | Non-renewable | Takes millions of years to form | | IV. Minerals | Non-renewable | Fixed quantity in the earth's crust and not replaced in human time |

So the renewable resources are I (Wildlife) and II (Forest).

Checking the options:

  • A (I and IV): minerals are not renewable ✗
  • B (II and III): fossil fuel is not renewable ✗
  • C (I and II): both renewable ✓
  • D (I and III): fossil fuel is not renewable ✗
  • E (all four): includes non-renewable resources ✗

Tip: Ask yourself, "Can it reproduce or regrow?" Living things (plants and animals) are generally renewable. Things dug out of the ground (coal, oil, minerals) are non-renewable. Remember: "Living = Renewable, Dug up = Depleted."
