Question

To conserve materials (resources), it is necessary to use them in ________.

• A. limited amount
• B. Both A and B
• C. unlimited amount
• D. None of these

Answer 1

Answer: (A)

To conserve materials, it is necessary to use them in a limited amount.

We need to use them judiciously for a sustainable environment.

The burning of these resources is a major cause of air pollution. Their use is also linked to global warming. It is, therefore, necessary that we use these fuels only when absolutely necessary. This will result in a better environment, a smaller risk of global warming, and their availability for a longer period of time.
