Sample questions with answers

The first 5 questions of this free test.

1. Q1. A public park, a road and a government hospital are used freely by all the people of an area. According to ownership, such resources are classified as:

   • A. Community (public) resources
   • B. Individual resources
   • C. Potential resources
   • D. International resources
   Solution

   Resources owned by the society or government and open for use by the whole community are called community/public resources, unlike individual (private) resources.

2. Q2. Trees are usually called a renewable resource, yet a large forest can disappear forever if it is cut too fast. The best reason for this is:

   • A. Trees actually belong to the non-renewable category
   • B. Trees stop being a resource once they are grown
   • C. The rate of use becomes greater than the rate at which trees can grow back
   • D. Forests can never be renewed under any condition
   Solution

   Renewable resources renew only if we use them slower than they can regrow; cutting trees faster than they grow back destroys the forest.

3. Q3. Resources like air and sunlight are found almost everywhere, while a resource like copper ore is found only in certain places. The correct pairing of terms for these two kinds is:

   • A. Both are ubiquitous resources
   • B. Air — localised; Copper ore — ubiquitous
   • C. Air — ubiquitous; Copper ore — localised
   • D. Both are localised resources
   Solution

   Resources available everywhere are ubiquitous, and those found only in some places are localised.

4. Q4. Using resources in such a way that present needs are met without harming the ability of future generations to meet their own needs is called:

   • A. Overexploitation
   • B. Resource exhaustion
   • C. Sustainable development
   • D. Rapid industrialisation
   Solution

   This careful, balanced use of resources that protects the needs of coming generations is known as sustainable development.

5. Q5. Assertion (A): We should conserve natural resources and use them carefully. Reason (R): Many useful resources are limited and cannot be replaced once they are finished. Choose the correct option.

   • A. A is true but R is false
   • B. A is false but R is true
   • C. Both A and R are true, but R is not the correct explanation of A
   • D. Both A and R are true, and R is the correct explanation of A
   Solution

   Both A and R are true, and the reason correctly explains why conservation is needed — because several resources are limited and non-renewable.
